I have a little bit problem... I put to my car new fuel pump... After the fuel filter I have on this pump about 3,5 pessure I can;t switch on the engine becouse spark-plug is wet in fuel I bought the fuel pressure regulator and don;t know what pressure should I put

 

What pump do you have? What spec is your car?

 

Walbro 255 and injectors from audi S2. I put old injectors from efi and is the same situations... I bought fuel pressure regulator and tomorow I will make pressure on the injector slat Now is about 4 On my old pump engine was up and running ( and the pressure on the injector slat when I starting engine was about 2-2,5) When I put new fuel pump becouse the old one was died I only have wet spark-plug and the engine wan't star I know that when I made chip evrything will be good but now I want to run-in the engine on the serial boost seting


My spec... Head stage 3 with bigger valve, efi managment, Piston 1,8 and much much more

 

Ok I put 2 bar on starting and now is better

 

Sorry im late on this one but somewhere around 2 bar should be fine initially.

We normally run around 35-45psi

 

What kind of regulator did you buy, and from where? I've been looking all over the internet to buy one that I can mount on my EFi fuelrail. I've seen burtonpower has got one that fits, but it does'nt have a gauge. So Im basically looking for a adapter to fit where the original fuel pressure regulator is on the fuel rail, so I can use the regulator of my choise, but I cant find an adapter like that ANYWHERE! Maybe you know?

Thanks!
