where are you going to mount it?

I mounted mine in the bed at the back on top of 4 pistons so I didnt have to cut the floor up,just poped 2 holes with the hole saw for the fuel lines

it gravity feeds down to my filter and pump hanging on the frame rail in the back

I run -8 from cell to filter/pump to the regulator up on the firewall,then -6 line to carb and for a return to tank

if you mount it higher than the pump and lower than the carb you should be good and have no problem with it

I have seen those long spun alum takes mounted to the bulkhead of the bed up by the cab and gravity feed the mech pump,looks good this way also,stays out of the way of hauling stuff in the bed too

I dodnt trust a BB fuel pump since I had one rupture and dump gas right into the oil pan and wipe a good running 440 out with gas in the oil...but thats me and why I went to a elect fuel pump
