The previous owner of the DJ jeep mentioned that water kept getting into the fuel tank. This will be fun to get working. A flat blade screwdriver and a hammer tapping on the fuel sender locking ring and we can get a look inside.
This fuel sender looks like it was on the Titanic.
That is a lot of rust inside the tank :(
The tank dropped out with the removable of 6 bolts and tons of dirt and rust.
I took the fuel tank straps off and pulled the tank off the skid… The skid has traces of old gas and varnish on it… Not a good sign for the integrity of the tank.
Filling the tank with water confirms my fears. The tank leaks.
I could try repairing the tank by removing all the rust and applying a liner but I think I am going to change to a CJ-5 Jeep Tank. Some searching online shows this won’t be a direct swap but it I should be able to make it work.
I ordered the following:
- MTS Company 0051 Fuel Tank
- Fits the 1978-1986 CJ Jeeps
- This is a plastic tank that fits CJ-5 and CJ-7 Jeeps
- Omix-Ada 17724.09 Fuel Pickup and Sender
- OE Reference: 5357373K
- Crown Automotive J5357023 Fuel Tank Skid
- My original skid does not fit the CJ-5/7 plastic tanks
- Spectra Premium ST60 Fuel Tank Straps
Tank assembled with the new sending unit, tank straps, and skid. I added some 1/16″ thick rubber between where the metal contacted the plastic tank.
The skid needed some trimming and holes drilled to make it fit the DJ frame and cross members. The tank and straps did not need to be modified.
One of the problems with this tank is that it moves the sending unit. Not a problem for the wiring and fuel hoses but the access panel for the sender doesn’t line up anymore. Not a problem for a angle grinder though.
I cut the access panel large enough to access the new location of the sending unit and then riveted in some aluminum strips so I could screw down an aluminum plate to cover the hole.
Still need to see why the fuel gauge doesn’t work but the sender works and the tank hooks up to the stock filler hoses for this 1979 DJ.
