Assuming no foam in the tank, start working it back. Take the filter element out and recheck it at the carb. If no change, check it before the regulator. If that's still the same, check it right out of the pump. Make sure the fuel cell vent is open. Let us know what you find. -Al

How old are your fuel lines?

Re: Question on loosing fuel pressure going down track.
Like other have said a gallon in 60 seconds is not enough volume. At your ET you would be getting less than 1 Qt. of fuel to the carb during your runs. a gallon in 30 seconds is right on the edge for my car.

Re: Question on loosing fuel pressure going down track.
No foam in cell. I'm going to bypass filter and retest filling time in bucket. I did notice once after shutting off car the cell acted like it was under a vacuum when I tried taking cap off. I will look at vented line to see if it collapsing or kinked. All lines,fittings,filter,pump,cell were all brand new.

Re: Question on loosing fuel pressure going down track.
Did you do the volume test with the engine running? It'll pump more, of course, when the voltage regulator is holding it at 14.7v or whatever it maxes out at.
As mentioned, are your grounds, connections and wire diameter up to snuff? |

Re: Question on loosing fuel pressure going down track.
Going to verify ground as car was a back east car and frame had some rust. Maybe move ground to rear battery.

Re: Question on loosing fuel pressure going down track.
Everyone is focusing on a fuel pump delivery problem , yet the engine goes rich in high gear . That seems to be the real problem .
