Default Fuel cutting 100% out uppon acceleration....???

i have a cell in my vega 16gal w/foam and everytime i get on it hard itll cut out completely and buck hard. not just die down from not having enough fuel, but almost completely shut off, i have a walboro 255lph inline pump and a corvette fuel filter with built in return i beleive its a fuel pressure regulator thats built in. i havnt checked the codes on it but i will soon.

does anyone seem to know what the problem might be with this? is there some kind of sensor for in the tank to read the pressure or anything? the ecu is stock. with a painless wiring harness.

Do you have a fuel pressure gauge? I had the same problem and it ended up being a crimped fuel line from when I put the walbro in.

is it only at WOT?

I have replaced a bunch of fuel filters lately for the car being a dog a WOT but run fine if you goto 3/4 throttle
