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.

Thanks for the info, bnaylor3400.

At 72gph, it eguals out to be about 275lph.
