Inline fuel pump vs tank fuel pump
Electric pump like to push NOT pull fuel. your to far away from the tank!
all i know is this pump is the quiet electric fuel pump i have ever owned, and the most powerful one.
Would by it again if i need to.
I have the stock fuel tank and pick up with a hole and fitting to sent the return fuel back to the tank.
I have had as little as a 1/16 of a tank(by my stock gauge) and never ran out of fuel(straight line launch)
If its leaking out of the sending unit for the fuel tank you need to replace the gasket or find out why it don't have a smooth mating surface to seal on.
