Fuel Pump One-way Valve

[CATKICKER]

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!!

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.

Yeah, I don't think it has a check valve... has anyone here done it before?

I got the same issue - my dodgy install I guess - But I still need an anti-drain valve!

Can It be fitted near the fuel filter in the engine bay at all ?

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
