Here's the setup I have on my Bronco.I used the stock tank but I had a sump welded in it. The pump is an Aeromotive,it's the Street strip pump(part# AEI-11203),not the H/O pump.This pump has to have an external regulator because it will flow 18psi pf fuel.The fuel system is all Aeroquip,I have a -10 (5/8") line going from the tank to the pump with a 100 micron filter before the pump. I have a -8 (1/2") line going from the pump to the rugulator, with a 10 micron filter after the pump. At the regulator I'm running a -8 return line back to the tank, and a -6 (3/8") line going to the carb. I could of used a pump that was already internally regulated but I wanted a return style instead.The system I have will support 700 horse no problem,it's a bit over kill but when I add nitrous the fuel system is already set up for it.
