Hey, I need some help installing a Bosch 044 (in-tank) into a S2 R33 GTSt.

I know roughly what needs to be done, but would like some help from someone who has done a pump install themselves. Obviously, I'm happy to reimburse you for the time taken ($$$ OR :cheers:).

I'm located in S.E of VIC but I'm happy to drive to you (unless you're on the border of NSW and VIC, which in that case I'm going to decline unfortunatley)

Either reply or PM me if you're able to help me out :)

Have a read through all the DIY fuel pump installs, Its a pretty easy job. If you know how to work a spanner give it a go yourself :-)

Hey mate, thanks for the heads up, but I've read through the DIY/Tutorials (before I began researching, I had ZERO idea on fuel pumps and how to do anything regarding it, but after scouring the forums, I know how to do it but need that little bit of confidence that someone experienced can bring lol). Cheers for the suggestion anyway :)

Isn't the 044 an external pump? Or are you planning on mounting it in tank?

Hey mate, yep it's an external one but I'm mounting it in tank. Quite a few people are getting great results using it in tank as it allows you to use a standard sock arrangement (would of chose 040 but I'm not a fan of the metal gauze bottom, which can't use the standard sock arrangment).

So for me, it was either the 044 in tank or the Walbro...... (p.s I've read ALOT of topics about Walbros and in almost all of them, you always appear and mention how it failed on you LOL :P )

Is the 044 physically bigger than the 040? Cause the 040 was a real tight squeeze to fit it in. It's not a difficult job just

time consuming unless you have little arms and x-ray vision :)

My 040 actually sits lower in the tank than the standard arrangment, which gives me a few more miles til empty...so I praise the metal gauze!

I'm not sure to be honest! But I'd presume it would be slightly bigger as the 044 weighs 1030grams whilst the 040 weighs 930grams.

Ahhhh k the, yeah I read one way to get around the 1/4 tank problem is to run the 040 lower, but you run the risk of sucking up all the crap on the bottom of the tank?

never heard of a 1/4 of a tank problem?

and the pump always sucks from the bottom, so there is no "sucking crap up from the bottom" as, it always sucks from the bottom

I've read that some people get problems with running with 1/4 tank or conrnering as the pick up isn't low enough so it starves and cuts out.

The mesh on the sock of standard pump is much finer than the metal gauze of the 040 isnt it?

i've got a Bosch 040 installed, don't seem to have this 1/4 problem - works fine.

Anyway, i was under the impression that the 044 is a much larger pump ment to be mounted externally of the fuel tank ? I had abit of trouble getting the bosch 040 onto the stock fuel pump bracket cos it was too fat from memory... not sure if the 044 is fatter?

1/4 fuel tank problem sounds like a problem someone who didn't mount the pump low enough in the tank would have. You do need to cut the fuel pump bracket and hose clamp the pump to make it fit.

Metal gauze on the 040 is plenty fine. They wouldn't put on a gauze that was going to stuff up the pump with debris...sounds like you've been reading reviews from paranoid androids :)

There's really not that much stuff at the bottom of the tank anyway. If you're worried about it, clean out the tank with a syphon. My 040 sits touching the bottom of the tank and I have no debris related fuelling issues. Didn't clean out the tank, haven't even changed my fuel filter yet (though a new filter is recommended at some point after a pump change). But if you've already bought the 044, well now we have to work out how to mount it in tank :miner:

Oh ok then, fairrr enough. Yeah, the 044 is slightly larger and it's meant for external mounting but the only reason I've gone for it was because I get to use the sock attachment lol

Hmmm..... that's kinda annoying for me then, cos after reading other people's experiences with them, they were complaing about it so I opted for the 044 LOL DAMN IT!! Hahahaha

I've got the 044 on order but it hasn't been dispatched yet, so do you think I should get them to change it over for the 040 instead, provided it's possible by them? Or should I just stick with the 044 and get it to fit by working at the bracket?

I highly doubt I'd find the limits of the 040, let alone the 044 (aiming for only 200rwkw until the turbo gives way and a high flow is needed). Like I said, only reason I went the 044 over the 040 (and Walbro) was because I could use the sock attachment lol

doesnt walboro use a sock? you should of got a walboro pump if you wanted the sock

Yeah, the Walbro does use a sock but I've read more negatives than positives from other people's experiances. Otherwise, I woulda went the the Walbro hehe

Anywayy, I called up Bosch and they don't recommend that the 044 be used in-tank as it can't be submerged in fuel and to go the 040, yet there's quite a few people who have done so with no problems.

All these dilemmas on me wanting just an upgraded fuel pump. FML.

Oh, and the 040 is the same diameter as the 044 (60mm). Only difference in size is that the 044 is 196mm versus the 040 at 169mm.

I got no experience installing an 044 in-tank, so can't really comment on whether you should cancel your 044 for a 040, but if you want to play it safe I would...because we at least know the 040 will drop straight in with a few adjustments (a hacksaw, a fuel hose and a solder of the terminals), which you would probably have to do anyway to get the 044 to fit in-tank.

Plenty of people running 300rwkw+ on the 040, you'll be fine with one of these.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

      What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
