QUOTE (Kazz5 @ Jan 24 2006, 04:04 PM) Walbro HF 255 ... hrrrmmmmm... and how do I check that? Fuel pressure guage. If its running higher than stock base fuel pressure at idle, you are overrunning the stock FPR. I don't know what the stock base fuel pressure is for Evo's. If its like the 2G's, its 43.5 psi with the vacuum hose connected to it. |
