Electric Fuel pums - fuel injection
What make and models of electric fuel pums are guys running for fuel injection? What's good and what to stay away from. I looking to upgrade from the stock fuel cool on a 502. Also any ideas on fuel pressure regulators?

hey smitty, is that photo of your own setup ? if so let me make a suggestion please... a long time ago an engineer from a manufacturer of data equipment told me that if i stopped hard mounting the sending units ( like your fuel pressure in the pic) i would get a lot more accurate output and a LOT longer service life . what he wanted me to do was put the sending unit at the end of a short piece of hose and soft mount the sending unit... in my case that meant a tie wrap w/ a piece of taped foam...
he was right. sending unit failure essentially disappeared and all the hysterisis in the data disappeared.

I just scraped my entire cool fuel system on my modified 502 MPI's and replaced it with a custom set up on my Top Gun. I only have about 550 HP per engine so I didn't need a huge pump. I wanted a pump with low amperage draw. After much homework I went with Weldon's 600A flow thru pumps. Not the cheapest but very good pumps and very low amperage draw. So low in fact that I used my stock wiring and relay. Pretty quiet and enough fuel flow to support way more than my 550 HP.
I replaced my tank pick up with 1/2" units then #8 hose to a RAMCO fuel/water filter then #6 lines to the pump then thru a second 10 micron filter then to the front of the fuel rail then out the rear of the fuel rail to a Weldon regulator then thru a fuel cooler and back to the tank. The system works great.
You will have to do a little welding and modifications to the fuel rails to attach the #6 lines. The stock lines are too restrictive in my opinion. and make sure you check to see if you have one of the fuel rails with the factory restriction feeding the #7 injector. You should open that up(very carefully) if you are uping the HP from stock.

Aeromotive 1000 for a hopped up 454 Procharger M-1, 6 psi. 42# injectors which you should have stock. I kept the cool fuel with the stock regulator taken out, replaced with a procharger base reference for the supercharger the stock fuel pump was replaced with a manifold that replaces the old pump works well and keeps the cooling. Cooling is important for supercharger detonation potential. Re- mapping the ECU was the best money I spent.
