Hi guys,

There are some terific guides to installing bosch pumps in this section which are also a great reference if installing any type of fuel pump.

Ive gone for a Tomei direct replacement fuel pump kit for a couple of reasons.

- Its perormance capabilities will suit my power goal

- Value for money

- Runs quietly

- Extremely Easy DIY installation as the unit is a direct replacement for the entire pump assembly :O

Heres what I did :

1 - Access fuel cell.

This is located on the right hand side of the battery.

(I had to remove my amps to get to mine)

It is covered by a plate secured by 4 bolts.

Remove the bolts to reveal the plastic 'lid' of the fuel cell.

This is white with a black threaded plastic ring with ridges on the side of it.

2 - Remove lid.

Unplug the 2 wires on the lid. there is a soft part which you squeeze to remove the plugs.

Remove the three hoses attached to the lid.

Keep a rag handy to absorb any spilt fuel. (Only leeks a little bit.)

Using a block of wood and rubber mallet tap the lid anti clockwise.

(This part is tedious)

When the lid is loosened, lift it up to reveal a black "O" ring and more wires and a hose.

Unplug the wires and hose from underneath the lid.

These dont fall into the tank so you can let them go.

Remove lid and black rubber 'O' ring.

(The Tomei kit comes with a replacement "O" ring)

3 - Remove stock pump assembly

Reach into the tank and gently pull and twist the top of the pump assembly (aka - cradle or bracket).

This comes out easily and in one peice.

4 - Install Tomei pump assembly.

These units come pre assembled with cradle, insulated pump, hose, clamps, wiring and pickup filter.

Look into the fuel tank and find the mounting point where the assembly is mounted.

Lower the assembly into the fuel tank and secure it to the mounting point (can be tricky).

5 - replace lid.

Reconnect the new "o" ring, hose and wiring to the base of the fuel cell lid.

Fit and replace the lid by tapping it clockwise untill secure.

Reconnect the 3 hoses and 2 plugs to the lid and also the plate covering the lid.

6 - Prime pump and fuel line

Disconnect fuse for the fuel pump (this is located in the little black fuse box near the battery)

Turn ignition over a few times to move fuel through the lines.

7 - Fit pressure valve.

The Tomei kit also comes with a relief valve.

I have a NISMO adjustable pressure reg waiting to go on so I didnt install the relief valve.

I was also told that the stock one is ok but I am not 100% sure on that.

Fact is I dont know how to install either the relief valve or pressure reg? And do i require a tune?

If any one knows how please post up the info.

:(

Certainly is nice and easy. $400 from Nengun aint too bad either.

Any idea if the included pressure regulator is the same as standard, or will it run a higher pressure?

I think it runs a higher pressure but not 100% sure? It is different to the stock regulator.

Any one know? :blink:

I got myself a Bosch 040 intank pump - anyone know if these are just as easy to install?

I've had a look at it and it doesn't come with any O-ring, hose clamps, mounting bracket or the pick up filter sock looking thing..

I have never installed an 040 but was going to at one stage.

Did some research and learnt that the 040 wasnt as good a fuel pump as it could be. So I went for the Tomei.

The 040 dont have a pick-up filter which leaves a decent sized gap from the pump to the bottom of the tank, thus causing surging on cornering and when your tank is low.

The 040 can be mounted with hose clamps to your stock cradle.(as low as possible).

Not too hard just a bit of stuffing around.

Have a browse in the DIY section, its been covered quite well a few times already.

Howdy ppls,

I would just like to give thanks as this guide was really handy. I just installed a walbro fuel pump. It took about 1 hr. I wouldn't have done it unless someone had posted this so thanks again.

I bought it off BT-Revolution and it came complete with all the fittings and even a rubber base to fit the cradle that it sits in.

The price was cheap and I chose it as the tuner advised it for pretty good quality and it is easy to fit as it's the same size as the std nissan.

I had a look and it seems to be good, made in USA, and it was a real one. It's funny how alot of people on this forum don't like them. There are a few chinese copies of this pump out there and I think people may have been stung from buying one and found the performance to be no where near what it's supposed to be. Anyway - just a theory.

Anyway - I've attached a picture of the pump installed into the cradle for anyone who want's to have a go at it. All the instructions above are well documented and spot on.

I don't mean to sound negative....but put a fuel pressure gauge on the walbro.  I and a couple of others have had dangerously low pressure at high revs from them.....

Hey Man, It's all good - that's what these forums are for.

I had my car tuned today after fitting a walbo, and the graph showed that the afr's went from 12.5 to 11 before tuning. So it's definatly better than my stocko. I'll post the graph when I get home.

I have heard people on the forum getting afr's of 10 after fitting a borsh though.

What pressure reading did you get? I was getting 40psi at 11lbs boost on the stock pump.

you may find the walbro's vary differently because they are rated at 15volts. in an r33 at least the wiring only gives 12volts so it never runs at full capacity. you need to run a 15v direct feed to it

Yer, I know. I bought a relay and some female spade connectors just incase. Didn't need them though. Enough fuel was being supplied to do the job I'm afer for now. If I go bigger turbo etc, I would relay it to get full use out of the pump. Incidently, the tuner said that he did an R33 with a walbro and got to 345hp before running out of fuel. He also said that some s13's are only getting 10v at the fuel pump, and that can be a problem.

But for now, I'm getting more power, and more importantly, no ping. Pretty happy with that. :)

im geting one of these tomei fuel pumps for my 32 so i want have to change all the wiring and make it direct to the battery like some do because they dont have enough power?? hope not becuase that sounds a bit difficult! these tomei pumps seem to be the goods!

They are definitely the goods! 6 months later and mine is still running perfect :P

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
