Use a rear mount electric pump.

Install a Wix (or equivalent) fuel filter with a build in return, and run a return to the tank. There are several ways to do this, one would be to modify the sender, or I believe you can buy repop senders with the return fitting in the sender flange. I silver brazed a return fitting into the front wall of the tank, after draining, and then flooding the tank with CO2 from my MIG

Wix 33040, 5/16, 33041, 3/8, or 33054, 5/16 with 90 output. All have a 1/4" return, which must be at the top of the can:
