i have 1989 gta 350tpi i have been having problems with my afpr i checked it with a gauge and it reads 60 psi i adjusted the screw up and down and no change so i changed the regulator it was a bbk adjustable or still is i should say.my ? is i want to use a aeromotive universal afpr up front whare the return and feed lines are located will this work?

 

Was the vacuum line on or off when you adjusted the pressure? I believe you need a min. of a -6 line to use the Aeromotive regulator. What fuel pump are you using? Did you recently install a KILLER pump. If so, its not the AFPR. Its the stock steel fuel line coming off the oem regulator. The sharp bend in the line is pinching your fuel, thus putting your pressure into the stratosphere. This is what happened to my car after installing the A1000 pump....Tom

 

i have had a tpis 400hp pump in the car for a year and a half and the car has allways ran good.what do you mean a -6 line. i have a EFI aeromotive afpr i want to install it in front whare the rubber lines are and mount it to the inside fender wall.

 

Correct me if Im wrong, but the Aeromotive regulator is machined to accept a large line. The threaded holes in the regulator, are NPT, and you would have to install an AN to pipe adapter in there. Then you will have to fabricate your braided line with AN hose ends. Not hard to do , but not easy either. If you never installed hose ends before, a little tricky, but no big deal. AN, means Army Navy and its the way the hydraulic fittings are rated in size. Example: -6, would be 6/16 or 3/8. -10, would be 10/16 or 5/8. -8 would be 8/16 or 1/2 inch. In this sizing, there is no 7/16, because you cant compute. No -7, all are even #s. Tom

 

your correct but the regulator has 3/8" NPT fittings.i think im gonna send it back and order the holly regulator and try one more time.maybe i installed the old one wrong or something or maybe theirs another problem.
