While this is true, I'm not running CP injectors... just the early (91) TBI model. The specs on the pumps are just enough to cover the pressure required and so any wear or age on them brings it below spec. I understand the return system as well, hence the 18 psi spring. For my application, the 7.3 TBI injectors are too big and would require less pressure (there's a site that specs psi and gpm's), optimally, the 9C1 cop car injectors would be the best and even if I could find them here, I might as well buy the ebay ones... and at about $200+ a set... just not in the budget.

Cheers,
Ted.
