Putting in a 255 lph fuel pump

If it's an in-tank pump, it's probably made by Walbro and will output the same pressure as the stock pump, also made by Walbro. I installed the Walbro 255 lph ILO the stock 95 lph in ym 95 GT vert and it was no issue for the stock FPR. You will be running the return line at about its limit when you're idling, though. Best bet: put in a gauge and watch the pressure as the engine idles. If it creeps up, replace the the FPR with an Aeromotive or equivalent.
