Bosch 040 Fuel Pump Install

Recommended Posts

G'day guys. I thought i'd save me some cash and install my 040 fuel pump myself. Now i searched in the tutorial section and was going by this tute: http://www.skylinesaustralia.com/forums/in...75&hl=bosch and all seemed to be going ok.

As i started to pull the hoses off (as per the tute) i got the top hose off, which only dribbled a little fuel, then i proceeded to take the bottom hose off (which is circled in red in the attached pic) and it started to absolutely piss out fuel. Is there something i have done wrong? In the tute it says the hoses should only leak a little, but this hose was pouring fuel out and i had to reattach it.

Any help would be appreciated as i dont want to put it all back together only to find out it was something simple. AND i dont want to have to pay someone to do it!

Heres the pic:

Did you take the fuse for the fuel pump off and then turn the engine over a few time to let all the pressure out of the fuel rail? If you didnt then fuel will come out of the hose for a little while.

Well i took the fuse cover off and unfortunately i cannot read Japanese....

I dont suppose anyone would know off the top of their head which fuse is for the fuel pump?

I have a pic if it helps...

I hope that tank is not the same as my series 2 R33 GTR. If it is the pump wont fit. I got a shock when I pulled out the pickup assemly to find that it was nothing like the pictures of the 040 being fitted to a series one GTST. You have a plastic screw on cap like mine, not a screw on plate.

i loosen the cap before i remove any of the lines. when fuel comes out i just let the sucker drain back into the tank. you may cop a face full though so be careful.

also, youve got some ugly looking wiring jobbie in your boot, clean it up before letting fuel all over the place.

mate if i were you i would disconnect the battery after youve depressurised the fuel system,just looking at that wiring you dont want any sparks near that tank.

Agreed, that wiring is horrible! =-o

Disconnect battery.

I saw a few steps of a R32 GTR replacement fuel pump when my mate did his.

From memory, he went under the car and hose-clamped off the fuel line (the high-pressure outlet one. Return shouldn't be too bad) where the line changes to rubber pipe for a bend.

That might save a lot of fuel flying back out in yer eye!

Thanks for the replies guys.

I ended up just taking the fuel pump fuse out and turning the engine over a few times. There was still some fuel spilling out but it wasnt too bad.

It was a bit of a mission getting it in but it ended up fitting.

And i agree with you guys, that wiring IS horrible, thankfully its not from my car, its a pic from the tutorial that i used as an example!

:)

    • So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.
    • Yea - From what I have seen from the video, the car idles like any R34 lol 50PSI of fuel pressure is hardly super abnormal, the regulator is working because the pressure remains static when the throttle gets revved, i.e pressure remains the same when manifold vaccuum changes. Bigger pumps on stock rails always bumped the pressure in the rail without using an aftermarket regulator to change that. Do you know what your IAC is actually doing? Has there been any data showing the stepper motor % etc? There's no way your idle is actually moving around the way the cluster(s) are indicating. You would hear the difference with the engine RPM flying to 3k and 1k in mere seconds. I'd be checking the wiring to the tacho. What the tacho is telling you and what the engine/ecu is telling you are different things. I assume your ECU doesn't display the spike. So whatever is telling the tacho to be at X rpm is doing something weird. When the going gets insane, you're on the wrong path. You've ruled out plenty of things that are working correctly/aren't the issue. Your idle isn't doing what the tacho is indicating. You have two seperate issues, I don't think they are linked, and the idle seems reasonably okay unless it's stalling which.. well, it hasn't. Troubleshoot the stall if it occurs by figuring out what your IAC is doing vs what it is being told to do.
    • So awesome! I love the RB with the exhaust on display.
    • NO HITS PRICE DROP   ENGINE - $8.5k ONO TRANSMISSION - $1.8k ONO  
    • If it has had a code in the recent past, the code should still be there waiting to be read.
