I used an electric pump/regulator kit from MrGasket.

I feed it from the fuel cell with a -8 (1/2" line) in/out of my filter/pump up to the reg. then fitting in the reg for gauges both sides

I used a -6 from reg/gauge to carb on 1 port

I used a -6 from reg/gauge back to cell with a restrictor (#2 Philips hex bit) in the 90* fitting at the gauge. I got 5 psi on carb line with 3 psi on the return line.

by circulating the fuel I am able to keep it cool running thru a cool can,the pump does not deadhead against a regulator, and does not run at freeflow with some restriction in the line.

you could use 1 or 2 gauges at the reg. with mech pump or a fitting as close to carb as you can get.
