dead s3r fuel pump replaced with walbro 255

[pharmsrt]

My stage 3r fuel pump was slowly dying. Car was running like crap at WOT. Finally figured out that the pump was going out. I replace the pump with a walbro 255 pump and the car runs like a raped ape again. However, I now have a hard start issue. It takes about 5-7 seconds for the car to start and then once I start driving the car will usually act like it isn't getting enough fuel after about 100 ft of driving. Then I can blip the throttle and the car runs fine. Does anyone have any idea of why I'm still having the hard start issue and the initial loss of gas after driving?

you're losing fuel pressure somewhere....when you installed the 255, did you replace all the relevant gaskets/o-rings, etc? Did you align the canister properly?

You have to have the tube that has the metal part pointing downwards to catch the gas that facing down . Then also be sure to turn the tightening ring to tighten the pump onto the tank. are you sure it isnt leaking whil eyour driving?

I know the cainister is aligned correctly. I may have installed 2 of the very tiny orings that go under the pressure regulator. As far as I know I'm not leaking gas, but I'm not sure about when I'm driving.
