If you go through my build up post , you'll see I did a lot of custom stuff.My whole fuel system is custom , not one thing stock on it <img src="/forums/images/graemlins/smile.gif" alt="" /> The stock pump should be fine as thats what a lot of people are running.I just ended up getting a pump that wasn't made for EFI , and it couldn't deal with all the issues.The proper pump works great , not one stall , and runs better than with the other pump.I left theother pump there , as I can swap pumps out in a matter of about 2 minutes if I get in a jam , just unsrew the hoses and screw them to the other pump and change the wire harness plug <img src="/forums/images/graemlins/kewl.gif" alt="" />
