Fuel pump set up
 

I upgraded my power over the winter. Now running blown 750's w/carbs. I'd like to know what kind of pump and regulator set up you guys use in this application. I'm thinking I need to step up to electric pumps with a bypass regulator. Aeromotive A1000's ?

yup, and make sure you have a really good fuel preasure gauge x2 as well. not just the one's mounted off of the carbs but one you can glance at on your dash every 30 seconds=) good luck.

Go with the Aeromotive.
Im just running a mild 509. But no problems for 3 seasons with the pump and bypass regulator.

I called Aeromotive today and they said the same thing. A1000 marine pump with a bypass reg. AN-10 line from the tank to the filter to the pump to the water seperator to the regulator. AN -6 from the reg to the carbs. 1800.00 plus plumbing....ouch

Thanks all for the responce:ernaehrung004:

I never had any probs with the holly blacks 140gph on a similar setup. Much cheaper than aeromotive.

I use the holley blacks also, but the aeromotives look cool. $$$$$$$$$

Yes its expensive with all the fittings. Don't forget a check valve after the pump if you mount it up higher, I put mine about 2 to 3 feet higher then the tank. I mounted the pump on a rubber pad to lower the vibration down a little.
I think its -8 for the return if I remember correctly to. You can save a fitting or two by screwing the filter right into the pump then the check valve on the out side of the pump if needed.

If you need any mounting ideas. I just put my regulator on a carb plate. Heres a blurry pic.

What's the check valve for? To keep the line full of fuel?

Are you feeding 800's with the black pump? Do they maintain fuel pressure under boost?

yes, to keep fuel up to the pump.

Yes, Chief 800s, the electrics feed in parallel with the Mechanicals to the Carbs. At idle or WFO the Fuel Pressure is 8lbs. 340 hours on the Chiefs now. No Problems.
