Had the 440 out last week.Fuel pressure started to drop.Went to probally 3 to 4 psi.I figured maybe the Holley mech pump was going.Put my Carter hipo pump on.Started it and had 6 psi.Took it out last night and pressure was 3 to 4 and goiing to 1 at 50 mph.Today I hooked up my test gauge and had 4 to 5 psi idling.Id think the rod.Only thing I cant figure is why it had 6 to 7 when I first hooked up the Carter.I have great flow from the tank witj 3/8 line.Thought maybe my Auto meter gauge was bad but I doubt my test gauge is also.Just seems at 1 to 2 psi my Dominator would run out of fuel.So do you think the push rod might be bad?Whats the OE length?Rocky
