If you want killer reliability and active fuel siphoning, you could consider something like a Camaro ZR1 pump. It has the option for remote pickups [that won't suck air] and returns fuel into the basket shown..keeping the pump submerged.


It'll take some fabrication work to get it in the tank, but it would be power to the pump, OEM reliability and one line coming out of the tank.
