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.

    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
    • OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
