Hi,

I am trying to find what the stock 1997-up GTP fuel pump specs are. I have done a search every where and haven't been able to find anything.

I want to know what they flow, etc.

If anyone knows I would greatly appreciate it.

Thanks.

Its funny that no service manual or tech document publishes the actual flow rate specs. I'm of the understanding a GM Delphi hi-performance electric fuel pump flows approximately 72 gph with a 6 - 9 psi outlet pressure.

It appears accurate because the aftermarkets produce flow rates of 100 gph and up.



Thrasher CAI, DHP v1.0 PCM, SLP Headers,
3.25 SC pulley, CAIT GMAF, 2.5 DP/Hi-Flow CAT,
u-bend delete, 160 TS, ZZP Stage 1 72mm TB,
TB spacer, MSD 8.5mm wires, Autolite 103,
Goodyear Gatorback Serp. & SC Belt,
Nitto NT555R Drag Radials
1/4 ET: 13.210 sec. @ 104.490 mph
