you dont need a pressure for them to opperate, they just wont flow as much fuel. At 40 PSI they will be 53.5#. The formula for this is: New rating= old rating x square rt. of new pressure/old pressure. Hope this makes sense.

All of the FAST injs are rated at 45PSI. [Per their tech desk].The 65's are made by DELPHI.. They rate theirs @ 3 bars, [43.5PSI], as do most injector mfgrs, that are used in hipo applications.
Given they are rated at 65PPH @ 45psi, at 59PSI, they should flow 75.05#/hr.
I test alot of the DELPHI's and find they are very irratic at operating PSI over about 65PSI delta.
BTW, they are a low impedence inj....
