i want to upgrade my fuel lines to AN lines.

the fuel tank is very confusing to me. im use to the fuel coming out of the top of where the pump is mounted not the bottom of the tank.

I know there are 3 lines coming out of the bottom of the tank. i assume one is feed and one is vent. not sure what the other one was. was it indeed a return?

whats the proper way to plumb this? does anyone know the size of the lines coming off the bottom of the tank? i want to use compression fittings on those instead of hose clamps.

HP goal is 600HP max. so i hoping one pump -8an feed -6an return

 

I think the stock hardline are metric, 8mm. However, I used a 5/16 compression fitting and converted the stock hardline to -6an. No leaks.
