Anybody Running A Fass 95 If So What Kind Of Oressure At Idle And At WotI Installed Mine Yesterday And It Idles At 15.5-16.5 And Wot Drops To 7 Or 8 At Wot With Box On 2x5 I Thought It Should Do Better Than That My Ddrp Done That Good KERRY

Are you sure its not a gauge issue first?.One would think that a 95gph FASS should keep up and not show such a significant drop in pressure.Where do you have the fuel pressure gauge mounted in the line at and are you also running a pressure gauge on the FASS unit itself to see what its showing at the pump?....Andy

There is either a pump problem or a line restriction. Typically hammer is right and there should be very little drop of pressure. Like myself I know I've got a AD150 but I've only got a 1-2 PSI drop from idle to WOT.Dropping more than 3-4 PSI there is a problem... 8|

i'm checking pressure with a mechanical gauge through a tapped banjo bolt on the vp44 inletkerry

Kerry,What's the update on your situation?Dave

still the same
