I have a 97 12 valve cummins running a fass 220gph pump on it to a p7100 that flows 466ccs, laser cut dvs, 4k gov springs, and a tork tek overflow valve. Truck also has a sump and 1/2" fuel lines. I have a fuel pressure gauge plumbed into the inlet line on the injection pump, it normally would read 60psi of fuel pressure, lately when I accelerate at 2200+Rpms it drops down to 30psi of fuel pressure and stays there until the Rpms go back below 2000 or so I'm not sure what's causing it didn't know if there was anything I should look for. Any advice would be helpful. Thanks.
