I cant get the rear gas tank to work. when i put it on the rear tank it stalls like it is not getting gas. how do i figure out what the problem is?

Sounds like the fuel tank switch is bad where it mounts on the frame. Between the tanks there is a switch that physically transfers fuel feed from one tank to another. These often become corroded and inoperative. However, someone may have disconnected the second tank for some reason, like a leaking tank or other problem.

You cane have bad transfer switch .

PS the inline transfer switch or if there's is a separate pump it may b bad .

i think its your in tank fuel pump. i had a similar issue with my 96

Raymond, I got a 96 5.0 and the rest doesn’t work either... when I switch to the back tank, even when it’s fueled up... it just stutters and dies like it’s not getting fuel... fuel tank pump???

How do I fix
