Subject: Re: Newbie with a fuel pump question. by SpectatorRacing on 2011/1/10 15:25:01 Racetronix uses Walbro pumps. At least they used to, it's been a couple of years since I talked with them. You can easily verify if it's your pump or your fuel pressure regulator. Attach a fuel pressure gauge to the fuel rail (sounds like you already planned this). You should have around 43 psi. If you don't, it could be the pump or the regulator. Clamp off the fuel return line for a second. If the pressure spikes, then the pump is fine. If it is low, it's probably the pump. And you don't need a 255 lph pump. Everyone on the other forum loves to tell you it's a performance upgrade, but there's no advantage on a stock car. I personally use a fuel pump from a 90's Chevy pickup truck. Cheaper and higher flow... |
