I didn’t find any thread on search so has anyone installed an in tank fuel pump using the factory sending unit?? If so what do you need to modify? Looks like the pick up tube lays sideways on the bottom of the tank and I am not sure if the pump will work properly. And the unit loads in on the side of the tank. I am also considering putting a module in the top and then use the sending unit line for the return. My sending unit is only working intermittently and needs replacing which means pulling the tank plus the tank has some leakage issues. I am leaning towards using a 72-73 tank either way and the there should be a little space above the tank because it won’t have the hump in the tank. Those so-called universal modules are expensive just to get a fancy mounting piece that won’t be seen anyway. Any experience with this is greatly appreciated.
