Upgraded Fuel Pump for 1990 SCSB 5.7

[Dropped88]

I put the same pump in a 92 454 and made a world of difference. But the stock pumps where barely up to the task when they was new

Yeah, that's were the idea came from - Had heard long ago the 454 needed the newer pump to run properly, just haven't gotten around to it.
It just recently dawned on me that my hard starting issues with the 5.7 tbi might also be the crappy stock pump.
The 91 454 that will be getting an EP381 as soon as I have the time.

Yeah I swapped the pump that come in the Delphi HP10001 into my blazer a few months back. The sending unit didn't fit but the pump worked perfect. Went from dropping down as low as 8psi during WoT to holding a steady 13 no matter what. My fuel tank was shockingly clean for having 260k miles on it.
