This is the GenRight Crawler™ EXT (Extreme) Gas Tank to fit a Jeep YJ (1987-1995). It is specifically designed to allow for more clearance between the rear axle and the gas tank so you can lengthen your Jeeps wheelbase AND keep nearly the same capacity as stock!
Wanna go to 40's? You are going to need bigger axles. This heavy duty tank is trail proven and made to accommodate such upgrades. Besides this production built gas tank is re-shaped to make more room under the Jeep for a stretch AND bigger axles! That way you can keep your back seat to bring the family on your 4 wheeling adventures. The assembly mounts in the factory location and is it designed to work with all your factory emissions equipment so you won't get and check engine lights or have computer issues.

The tank is beautiful. The tig welds are awesome. It's a shame to hide it all up under the jeep. The YJ pump/sender assembly matched right up. I didn't even need to adjust mine for length. The rollover valves come pre-installed, along with the vent tube and a 't' that the factory vent line plugs into. The tank arrived already mounted and strapped to the skid plate.
This thing is *heavy*. Good thing is was packed well because the box was hammered by the time FedEx got done with it. The tank was all good though. Wrestling it in by myself was a chore but doable for one person with a floor jack and patience.
The install was not completely without issue. I had to clearance both body mounts to allow the front mounting ears to come up high enough to level the top of the tank and allow the rear mounting tabs to sit flat on the frame. It only took a half-inch or so but it wasn't mentioned in the instructs. That meant having to get the tank in position twice before the final install. Once to mark the body mounts for clearance and a second time to mark the front mounting holes. If you're working alone, be very careful going up and down with the jack. It's a very precarious balancing act. Speaking of the instructs, they have you drilling the inside hole for the frame anti-crush sleeves to 5/8" but the provided sleeves are 3/4". While that was disappointing, it would have been *very* frustrating had I not had a 3/4" drill and needed to find one on a Sunday. All four provided hose clamps for the filler neck were the same size. Two of them were just barely big enough for the smaller vent line. The other two were never going to fit the filler hose. Luckily I had a couple clamps in my stash.
Getting the filler neck tubes installed and lined up with the body was a test of my patience. I am certain there is a better method than the one I chose.
All-in-all the product is a solid design and very high quality. The instructions could just use a little tweak.
There is now gobs of room behind the diff - Mission accomplished! Thanks GenRight Bill M in Reno on Feb 4th 2019
I am now adding this to my LJ PERFECT fit and allowed the stretch and room to rout the exhaust out the back. I have the same tank in my TJ. LOVE EM BOTH. Gary S on May 18th 2016
