I have a FiTech also. I have the Fuel Command Center under hood, and I guess those can be a bit problematic (the pump) exposed to heat. I went through two. It seems to be fine now though. I've protected it a bit with some heat wrap also. Mine is on my '89 Diplomat AHB and finding another gas tank that I could use a pump in wasn't working so that's why I have FCC. I'd prefer the sumped fuel pump instead to eliminate heat issues with FCC.
