Fuel Tank Mounting
It's been a while since I've checked in. Glad to be back. And I have a question.
I have an 89 YJ, 258. I installed a Warn gas tank skid plate 3 or 4 years ago. While on a trip on Utah's Hole In The Rock trail I discovered that the tank was floating loose inside the skid plate. There was nothing I could do for a proper repair so I used a cinch strap to stabilize the tank. I did not remove the skid plate. I have been using this way on several short trips. Since I had some time now, I thought I would fix it. I had to remove the tank and the skid plate and the rear after market bumper which kept the skid plate from dropping down.
I discovered that the T fitting on the front of the tank mounting strap had snapped off the strap. There was nothing to hold the tank in place except the skid plate. There was one strap in the middle. Looking at the factory service manual for my year and model, it shows two straps both off to the side and none in the middle. The Warn skid plate instructions show two straps but notes that some early YJ's had a single strap. Since I just installed the strap in its original location when I installed the skid plate, what I have now is the way the Jeep came form the factory-a single strap.
Researching the straps, what I found was a three strap set for my year and model. The Warn skid plate has slots for three straps. The Jeep dealership parts manual also shows a three strap set. The problem is I don't know if a three strap set will work for my tank. So, other than the note from Warn, I have no other information about a single strap set up.
How do you think I should proceed? Should I try to install three straps or stick with one assuming that the center strap in the three strap set will work? I can't buy a single strap.
Also, have any of you had problems with broken straps? The one I was using was after market from Crown.
One more. Is it true that converting to a 20 gal tank by shortening the fill vent tube only applies to 91 and later models? Does that mean that my 89 would actually need a new 20 gal tank? IOW, the 89's actually had two different tank capacities, 15 gal and 20 gal?
Thanks a bunch, Sparky
