Rear fuel tank for 1988 Grand Wagoneer

Postby 88amcsuv » Sun Apr 29, 2018 6:09 pm

I would like to know what fuel tanks people are using to move it to the rear center or spare tire area. I would like to move the tank and also have a larger tank. I'm still running a carb so being fuel injected compatible isn't necessary. I've seen different ones but have lost the information I had. Been sick for a number of years so I'm out of the loop you might say. Would love to know what year make and model of vehicle to use so I can order one. I would have to order one because all used places around me knock holes in them for EPA. Thanks in advance for anyone that can contribute to this thread.

I installed a tank from a zj in my 89. A little grinding on the inner frame rails as the tank just barely rubbed. Once the frame rails where ground down a bit the tank fit right in. Used two angle irons front and rear to attach the straps from the zj to hold the tank up. Used stock zj pump and sender and a bypass fuel regulator to reduce pressure to keep carb happy, old vapor return line works great as fuel return from regulator. I also took the skid plate from the zj, cut down the sides to fit under the tank since it sits higher in the frame then it did in the unibody zj. As far as the fuel gauge I found a module from Tanks Inc. that can be programmed to match sender to factory gauge. Top it all off the zj tank is 23 gallons so a bit more from stock. Been running this set up for about 6 months now and works great. The fuel gauge module is a bit tricky to get accurate but I just fill up at 1/4 tank to be safe.

How much does it hang below the frame?

How about some pichers?

I'm looking for a aux tank to put back there that doesn't hang too much below the frame. Something less than the stock trailer hitch.
