Belt drive pump on carb engine.

<< < (2/2)

retroboy:
Thanks for your thoughts. I have an Enderle 80A-1 here but can't help think it's just too big at it's rated 7.1 GPM even thought it would be simple enough to set up with a poppet and a pill in the return line. I like Glenn's pic with what looks like a simple 140 GPH pump and regulator but how do I know if it's delivering enough? If I went that way I think I would put the regulator after the carb in a return line to the tank or am I over complicating  things.  I work with centrifugal wine transfer pumps everyday and know they hate a small suction hose because of cavitation.  Most of the style of pumps Glenn has shown have 3/8" fittings - so do they flow enough for methanol?  I like the simple electric set up. How do I work out the amount of fuel required? I'm starting to ramble
Cheers

If you have the room, bolts to the stock pump mount.

FF @ 450gph & 50 psi   must use their reg to tone it down
designed for carbs, compatible for gas - alky - E85 (with the correct plumbing) about $300 US,
