if it is, it will be on the fuel rail(s) and have a vacuum hose attached to it;
- find out your fuel pressure:
vacuum-referenced: pull the vac hose and measure it,
non-referenced: measure it;
do you have any [electric/electronic] device that alters pressure...?
- find out injector rated flowrate:
if not stock, what is their rated flowrate and rated pressure...?
2001 corvette z06, racetronix pump w/ hot wire harness, 30# red top's... everything else stock as far as fuel...Quote:

Does it vary with RPM or load...?
Are the 30# red tops rated at 30 lb/hr @ 43.5 psi, is this correct...?

yes as far as I know thats what they are rated for..
Anyone who knows what pressure this runs at, please chime in...Quote:

Set it at 58 PSI.
I ran a stock C5 fuel pump fuel pump with mechanical gauge off the end of the fuel rail. Taped the gauge to the windshield and Seemed to be rock steady @58# thru 89% IJC> SVO 42s. The same with my fancy intank after market pump.
So consensus for Racetronix is 58 psi, same as stock...
And steady across the range of IDC.
Ok, thanks. :cheers:
