Hi Guys, just quickly...

I replaced my stock fuel pump a while ago with a bosch 040 in my R32 GTS-t.

Since then, I have had trouble starting it (have to wait for it to fully prime the lines and pump the gas)

I believe this is due to the factory pump having a valve in it to stop fuel draining back in the tank. Hence my problem!

Can someone give me a couple of pointers? Firstly, where do I purchase a suitable valve and how much should I expect? Also, where is the best place to fit it? Is there enough space just after the pump at the top of the cradle in the fuel line ?(it's pretty tight there from memory, I am guessing as close to the tank the better).

Anyway, thankyou in advance for you help!!

Todd

i have a Walbro GSS 342 and it came inbuilt with an anti drain valve,a nd semas to work ok.

I have noticed however, that if the car is really hot, it take a bit longer to get started since the new pump, an adjustable fuel reg will fix that a little. It's like it fired 3 cylinders and then the rest come to life very shortly after that.

a mate of mine just fitted one, to a bosh pump, go to a place next to Autocraft called, on collin steet, not sure about name, very new place, they sell all BOSCH pumps and geat a great bunch of guys, look out for the yellow bosch boxes, they'll sought you out.

the antidrain valve is usualy fitted in the fuel tank, so you always have fuel in the line.

Try Auto Service Solutions in Collin street on 62313499 they have boch and walbro pumps and valves to suit.

Thats where i got my GSS342

    • Are you suggesting that the kit did a cheap and nasty job of just jamming the wheel in between other things and caused the misalignment? I mean, we normally do this with an integrated crank trigger wheel, not something bodged on. It's not 1995 any more.
    • I mean, given the number of BMWs you own their tolerance for improper torque is rather low. The number of torque + angle spec bolts and non-reusable bolts in one is nuts.
    • Atmospheric vent requires something that doesn't use a MAF for load. You would need a standalone ECU for that.
    • Hey all,   I’ve got an RB25 with a trigger kit that includes a crank wheel, and I’ve hit a wall trying to sort a timing belt tracking issue. The belt either rides right on the edge of the cam/crank pulleys or walks slightly forward once the engine starts. It tracks okay-ish for a moment, then creeps right to the edge—and honestly, it’s stressing me out.   I’ve spent hours removing and reinstalling the belt, double-checking everything:   Tensioner setup is good, checked multiple times Idler pulley and washers are all in the correct places Followed the RB25 timing procedure step-by-step     The only thing I changed was the rear crank washer—I swapped the OEM one for a Neato version, and it made things worse. The belt now sits even more forward than before. I’m beginning to think the crank trigger wheel itself (from the trigger kit) is the issue—poor design or slightly off dimensions.   What’s strange is that with the previous belt setup, it actually ran fine for a couple of years—around 4,000 to 5,000 miles, even with hard driving and high RPMs. But even then, the belt was always riding right on the edge, and I know that’s not ideal or safe long term.   At this point, I’m debating whether to:   Machine a few mm off the crank trigger wheel to bring it back in line, or Replace it entirely with a better-designed unit     Only thing is, I already have the Cherry Hall sensors, bracket, etc.—I just want to replace the wheel only, not the entire kit. Anyone know a brand or supplier that sells just the crank trigger wheel on its own?   Would really appreciate any feedback—especially from anyone who’s run into this exact issue and found a reliable fix.   Thanks in advance.
    • Hi...a little refresh. Is Nistune gonna be enough to run BoV? Or do i need some proper ECU?
