Question on loosing fuel pressure going down track.

Is this a stock fuel tank? Not a fuel Cel?
To eliminate a weak (low volume) pump, I would add 5 gallons of fuel. If that stops the pressure drop, it will usually indicate the pump pick up being uncovered due to placement in the tank.

It is a fuel cell with about 10 gallons in it mostly to make weight. Has rear sump and exit with pump directly behind it. Im pretty sure I 45 degree or straight fitted everything. I did install a -8 inline fuel filter when I built car 35 passes ago.

It's the G force causing the problem.

What side of the pump is the filter. I have never ran a filter in my fuel system

If you are using a fuel filter, check the Microns.

I have the filter mounted near the passenger door. Pump is directly behind cell

Jeff did you get a chance to check the volume in a fuel jug for 60 seconds at the front of the car and what volume did you get?
