I have a Mag 4.0 5 cylinder engine that I'm going to put in an acrobatic plane. This engine will burn a lot of fuel so I want it at the balance point, i.e. under the wing tube, but this is almost 2 feet behind the carb. I thought I would put a small feeder tank near the carb, my question is how to pump the fuel to the feeder tank? The engine being a radial makes it so I can't use a Perry pump, either the crankcase pressure powered one or the vibration powered one, so how would you do it simply and lightly? What would the plumbing of the two tanks be?

An electric pump and regulator?

Exhaust pressure through a check valve and a regulator?

If two tanks, you hook them in series so the first tank sucks (or is fed by) from the second tank.

Where would you get a regulator for fuel, does anyone make one?

There is the Perry and the Iron Bay

They are "On Demand" pressure regulators. There has to be a 1" W.C. negative pressure on the outlet or they will not open. You mount them close to the carburetor.

Thanks, that's exactly what I need.
