HI Guys...

Shopping for a fuel pump for my 5.9l Magnum
a pump mounted on the side rail of my 67 Barracuda. I have choices for 185 lph and 250 lph and 1/4 inlet and 5/16 (Prof Product from summit).....wich one to choose ?

Stock engine and computer

Thanks for the advice

Daniel

No idea on the volume needed ?

I used the MSD fuel pump from summit. Was like 95 bucks. Probably the same as the summit pump. 3/8ths inlet, 5/16's outlet.

Was fine for the 98 and up that needs the 50 psi, but don't know for the 97 and down what psi rating you need.

thanks for the info..

Andrew...did you install a return line or just a single feed ? I nned 45 psi....the pump pushes to 85 psi...

Dan

I used an aeromotive regulator with a return line.

I put efi rated rubber hose from the pump at the back of the car all the way up to the engine where I put the regulator.

Cut the old fuel line at the fender and used it as the return to the tank.

Got a new sending unit 3/8ths and then had feets weld a 5/16 return line into it.

With the regulator wide open, I still have 20 psi at the regulator, but I honestly think that is as low as it regulates.

It will hold 50 psi for about 2 weeks after I shut off the pump.

I could not find anyway to do it without a return line except the intank self regulated fuel pump. But since I couldn't figure out how to get it in the tank, I went this route. Overall the same cost I am sure, but this way I have less expensive parts to replace.

Andrew,

What would you think if I'd use a pump rated at 45psi non return line ? Aeroquip AEI 11109 ?

Daniel

I could be wrong, but I don't find that pump. I found an aeromotive one with that number.

I don't think that rating means what you think it does. You have to have a regulator to get 45 psi. That rating is just what it will pump at 45 psi back pressure.

I do not know of an efi regulator that does not have a return line.
