Fuel Tank Modification

So, naturally, you're probably wondering how you actually change the tank in order for the jeep to start using diesel. Well, good news. It's really easy. All the original fuel lines, tank, and gauges are keepers. First thing is first, we had to drop the tank out. You don't have to unbolt the straps, just the skid plate.  4 Bolts in the rear and 2 up front.  Disconnect the various hoses.Once we got the tank out we siphoned out the majority of the gasoline. I let it sit outside overnight to evaporate the remainder of the gas. The next day I took a few clean rags and cleaned out the dirt and loose shit that had made its way into the gas tank over the last 13 years.Next,  I shifted my attention to the fuel sending unit. Here are the steps you need to take to modify this unit to work with the new 4BT.

1. Remove the aluminum canister from the sending unit.
2. Disconnect the old fuel pump and remove the wiring also.
3. Attach a piece of tube, I used diesel rated fuel hose.  This should be able to reach the bottom of the canister.
4. Re-assemble.
5. You're done.

After the I re-installed the sending unit into the tank and connected my feed hose and return hose. I chose to fit a bung into the top of the sending unit for a new return hose. Not necessary since the tank has two bungs on the top for fuel return. I didn't want the "T" in my line.Finally, I just reinstalled the tank and connected the lines to the existing hard-lines on the jeep. Larger line is the feed, smaller line is the return. Be sure to try and clear the hard lines of gas. Blow them out and let them sit open long enough to evaporate any old gasoline.  That's about it. I'll be using regular hose clamps on the connections to the motor, and installing a inline fuel filter as well.Lessons Learned
