Well today I made a pass at the track for the first, seemed fine not great times but i was still shaking it down. They go back to start my car and it barley runs and touching the pedal does nothing. So its not drivable and will start but shortly die rigth after. Get it home and have no fuel pressure. My question is this defintly the pump? and what would a good replacement be? Walbro255?

 

anyone?

 

It seems likely to be the pump, but I wouldn't say definitely. Be sure to check the other related items like the fuel filter & pressure regulator. Can you hear the pump prime when you just turn the key on? Have you put a fuel pressure gauge on and then test?

There's a thread (which I can't find at the moment) that has some feedback on which pump replacement was the most popular amongst people here and I believe the majority voted for the Racetronix Walbro 255 kit.

 

i have that kit sitting here. pump isnt cycling-no fuel pressure. it was fine when i first got the car running but i guess it could nit keep up with the 30lb injectors when i ran it at the track. Just not sure how i want to replace it, access panel or drop the tank what do you guys think. thanks
