1988 2WD MJ 4.0L w/5spd.
The fuel pump hasn't quit (yet) but is noisy and when starting both hot or cold has a drawn out cranking time before starting. Years ago with my 88XJ it was the fuel pump check valve allowing fuel to drop back into the tank & pressure to drop.
I crawled under the MJ and saw the sender unit is mounted into the tank side not the top and wondered how low does the fuel in the tank need to be before removing the sender unit?
1/4 tank? 1/8?
