I need some major help. I have burned up four pumps replaced the sending unit twice and put a new set of fuel lines. The parts replacer at the stealership cant figure out what is going on. The first three pumps were ford pumps and the last one was an airtex. I had the regulator shimmed till the second pump went out then I put it back to stock. I have stage 2 stick from Casserly. I thought maybe the sticks wanted to much fuel so I had a Fass 150/150 put on and the pump still burned up. PLEASE HELP!!!!!!!!!!!!!!!

have they checked for restrictions on the lines?
do u run ur tank low often?
i know on some trucks that the computer changes the output of the fuel pump based on demand ? but im not sure if that is true on the fords

Supposedly they have check for restrictions and voltage jumps but I dont know for sure. I usually fill up around 1/4 tank.

the fass did they wire it straight to batt with a relay kicker off the stock pump wireing.Also if your suction is restricted you'll tear em up.Low voltage and high pressure
