I have a 1979 TE51 SR5 and am trying to convert to electric fuel pump. I have tried mounting under hood, and it starts cavitating after a few minutes, I moved it to just forward of the fuel tank, mounted low, and it still cavitates after a bit. Has anyone else has any experience with this problem, or has converted theirs to electric pump? I am mainly doing it, because its hard to get to the OEM Mechanical pump, and its hard to get a NEW and not NOS mechanical pump anymore for this vehicle. I have installed countless electric pumps in other vehicles, and never had this problem. Thanks in advance for any help.

Hi dude, first thing that comes to mind is a bad pump. elec. pumps do like it closer to the tank, as they push better them sucking the other thing i thought of is a rust pin hole in the pick up tube in the tank. i have seen it before, but not very often. try adding some fuel to get above the hole. elec. pumps have a short pump stroke, and mech. pump has a long through and might draw it past a small hole. but, i really dont know. let me know what you find out please ken

Thanks for the reply. I did fill the tank full to see if that might be the problem, but did not help. The original mech. fuel pump has 3 lines, inlet, outlet, and return. Any idea what to do with return, and could it be my issue? Thanks

the return line could cause it, not sure. try capping or run it back to the tank. maybe try run a temp line back to tank to see if hole is midway i have elec. in mine. maybe try Rock auto for a mech pump. they are cheap, mostly name brands and i was amazed at what parts they had for our cars. i got about $600 in parts for a tiny $260
