Fuel Pump
I am wondering what is best electric fuel pump to use for my motor. I have a Shafiroff 540ci, 725hp in a 69 Camaro. It will be mounted in and under rear of car so I need something to get fuel to motor. If it matters,I also plan on using a 100 micron filter before pump. Also another question, I am using a #12 line from tank to pump and #10 from pump to regulator so will my #8 return line be OK or is a #10 needed. Have been told both ways that #8 is Ok and also to small. What about tank line, is #12 OK or can a #10 be good enough. Told I need a #12. Thanks!

I think your right on each. You should step down 2 between each; tank, pump, regulator to carb. Start with 12an; 10an; 8an. The #8 is right on the return also. I would advise a Magna Fuel pump 500, but BG, Aeromotive, Product Engineering are also good. I like the Magna Fuel 4 port regulator. I usually plug two ports on one side making it easier to run fuel lines to the carb. I also run the filter after the pump but before the regulator, but I think the way you have it will be fine also.

One more thing to add, I see the first post racebob, looks like you have a return line to use from the regulator, can you still use a return line from the regulator with the magna pump, it has a bypass at the pump already? and my system runs a return from the regulator also, do you block the return from the pump, on a magna pump?

I have a question concerning a few responses. A few of you said that you
put a filter after pump. I was told and I also called BG and they say a fuel
filer should be put before pump to filter fuel before entering it. BG said a filer can be put between regulator and carb but not between the fuel pump and regulator which a few reponses said. Any feed back is much
appreciated. Thanks!

I agree. Filter before pump (how mine is) & filter after Reg. Also I have 10 from tank to pump, 8 to reg. & 6 to carb BBC 427 (works fine)... in your case I agree using 12 to 10 to 8an for your mtr as it will need it more than mine. If a electric pump such as a Magna flow pro-star 300/500 is used, I do not see why you can not run it on the street! They always advertise "for extended & sustaned use". Properly set up for the street, that is excatly what i would use. Good luck & have fun!
