I know this has been covered before, but I've added pictures to help.

- Gather all parts that you need. Fuel pump, fuel filter (highly recommended to replace), fuel hose and EFI clamps.

- Remove all boot trims and whatever else you have in your boot.

DSC03537.jpg

- Disconnect the negative cable on your battery.

DSC03539.jpg

- To the right of the battery there is the cover to access your fuel pump.

DSC03540.jpg

- Remove the four 10mm bolts that hold the cover to reveal the top of the fuel pump housing.

- Use some pliers to remove the hose clamp and disconnect the hose on the left. Use your fingers and pinch the fittings to disconnect the other two hoses on the right (They are a little tight).

- Using a screwdriver and hammer, carefully tap the collar anti-clockwise to remove.

DSC03543.jpg

- Lift the upper section of the fuel pump housing and then remove the remaining cradle off the bracket.

DSC03544.jpg

- Your about half way there!

DSC03545.jpg

- Disconnect the wiring off the fuel pump using an 8mm socket and a Phillips head screwdriver.

DSC03547.jpg

- Loosen the hose clamps and remove fuel pump and rubber from cradle.

DSC03548.jpg

- Install a new section of hose about 5-7cm long with a new hose clamp on the cradle to the pump.

DSC03559.jpg

- Install a new section of hose about 50cm long with new hose clamps on the top cover to cradle.

DSC03556.jpg

- Using a hack saw, cut off the end of the cradle and file until you have a smooth finish on the metal.

DSC03560.jpg

- Install new Bosch fuel pump and take note of the position where it needs to be.

DSC03561.jpg

- Your almost there! Cut off old terminals on wiring and use about 7cm of new wiring to solder on new terminals.

DSC03562.jpg

- Install wiring and there you have it. At this stage, it would be a good idea to use some parts cleaner to clean the top cover.

DSC03563.jpg

- Start by inserting the fuel pump and cradle section back into the tank.

DSC03564-1.jpg

- Using a torch and some skill, install the cradle back onto the bracket. (Double check that it is installed correctly).

DSC03565-1.jpg

- Reinstall your hoses.

DSC03566-1.jpg

- Reinstall the collar. Use rubber grease on the collar and also rub some of the fuel pump O-Ring.

DSC03567-1.jpg

- Plug it all in, reinstall the cover with 4 10mm bolts, reinstall all boot trims and reconnect the battery.

DSC03568-1.jpg

- Replace your fuel filter (No pictures it is straight forward).

- Start your car and everything should be perfect :angry:

Anybody doing this themselves be advised I would NEVER recommend using what appears to be standard garden hose in the pics. Go to an auto parts shop and discover just how cheap a metre of correctly sized fuel hose can be.

LOL @ garden hose... i don't think anyone would but its a good call.

The green FUEL hoses i used as pictured are actually quite expensive - Speedflow @ $30 per metre.

i refitted my bosch 040 in my 33 after the guy owned it before me sta it in the factory position so i could use a full tank of fuel and get rid of fuel surging round corners, was a good write and showed me where to position the pump correctly to get the most out of it without the noisy pump issue

just becarefull as i had mine suck up a pump full of sedement and had to pull the tank out to clean it, this is not a fun job on a R33 at all.

As Jet 20 mentioned, the 044 is an external pump, therefore it requires surge tank etc but intank is still possible.

You can still modify the cradle to fit a Bosch 044 pump. I bought an 044 (NOT an 040) pump off dangerman. He had it all set-up to go intank. Even my tuner was impressed as he'd never seen it done before.

Hi, I've got a 044 in-tank and its very noisy, it that normal? Also "nathan76", how did you remove the fuel tank? Is it simple or do you have to dismantle a few things to get to it?

thanks

I'm definitely green when it comes to fuel systems... so i'm just curious does everyone who chucks in a 040 NOT have some sort of filter on the end of it? like the oem or walbro? sounds like a very easy way to get shit stuck in your fuel lines... sure the fuel filter in the engine bay may stop it... but still there is alot of piping in between.

Cheers

There is a filter/mesh on the bottom of the 040 pump

Just wanting to know how to attached the wires to the top of the pump?

I see you put "O" terminals on the wires, but what size nut (if you used a nut) did you use to attach them to the pump itself?

great write up, will be upgrading to this pump due to this write up haha! looks nice n easy!!! Cutting the bracket where the stock pump sits then hose clamping the pump to the cradle that remains perfectly fine? I cant see why it wouldnt be, anyone had any issues? So the aftermarket pump does have the same 'sock' the standard pump has?

No, the Bosch 040 is internally filtered, it is the mesh on the end of the pump. Also to answer my question about the Nut's, you need to use a 5mm and a 6mm nut. The positive and negative poles are 2 different sizes, also for the new wiring you can use normal hook up wire - i spoke to an auto electrician, i would suggest maybe a 15amp rated wire.

I shall be installing mine soon enough.

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
