Carter P4600HP Questions
« on: December 10, 2025, 04:39:52 PM »
My manual fuel pump, with less than 5 hours, decided to crap out on my 445. I used one of the Carter P4600HP pumps on a GM 383 build I recently did. While I have not put that motor through its paces, the pump seems to be ok at steady speed or quick zips. It is a little loud but not once the motor fires you can't hear it. Overall, I have had no complaints on that one.

My question, assuming 3/8 lines, should this be enough to feed a solid 500Hp/550Tq FE? Running a single 750 Vacuum secondary.  This FE is a bit more healthy than the 383.
Anyone run one, good, bad, ugly? Based on the specs I think I am fine. I deadheaded the GM, and likely will do the same on this one for now.

We run that same pump in our 79 Foxbody Mustang race car with a 445 FE. Were running a 1050 dominator, shifting at 6300. We never have had a fuel starvation problem. Were going on 6 years of racing with the same pump. I have a thread in the dragging racing section of this site with all the specs of the engine.

We used on a "daily driver" 79 F150 for the better part of 6years with NO issues in a "dead head" set-up. That particular pump was a "USA" made version. I believe the current pumps are built "offshore" so I dont know how long they would last.

Thanks for the responses. Oddly I got one off Ebay, it was too cheap to be true, and it is a bad China copy. I knew better but thought since it was in Jersey, and not Cali, maybe it was someone clearing stock. The studs for the electrical were not even threaded. New one is now on order direct from Carter.  The knock off stuff has been bad, but seems to be at all new levels recently.
