Due to troubleshooting my fuel system issue I may have damaged the stock fuel pump anyways (activated bap for a couple full pulls to troubleshoot bap vs. Pump) so I feel the stock pump needs to be replaced anyways. Would a single walbro 450 intank generate alot of heat and an external secondary (ecs stg 1)?

Do you feel that me basically over spinning the stock fuel pump for 5mins +/- straight would have damaged it? I dont necessarily want to drop tanks....but all the drivetrain will be out of the car for clutch install.....so now would be the best time

I would doubt it, but really don't know for sure. I was always under the impression that a BAP wont hurt them, so I don't see why 5 minutes would.

Fuse blew as a result of forcing the the bap to stay activated......when i was driving it that way,car kept going lean under boost. Pulled over to unhook jumper wire on hobbs switch and car died. Towed it home,found blown fuse,replaced and car started

Great info in here and I know I'm now reviving this thread... again. i have an 08 car and have concerns about the factory fuel pump putting up with E85. Seeing how I might go in and replace the factory pump with something that might be more E85 friendly, should I just ahead and do in tank pumps, or is it still not worth the hassle and I should just swap the internal pump with a nice single that won't overly heat for typical driving and do external pump(s)? I currently have the single A&A external with my factory in tank pump at 800whp on 93 and some meth. Goal is 2200R on build bottom end 427 and flex fuel (E85 as often as I can) with meth for IATs. Seeing some conflicting info if 1300X injectors are enough for #85 and up to 1100whp...

As for the 1300X, that's what I went with and I designed mine around 1250hp max. I'd talk to Justin at Fore to see what he recommends in your specific situation but should be good.
