KatahGii Posted November 14, 2019 Share Posted November 14, 2019 I have a 1986 Jeep Comanche X I don’t know the bed length. I need to replace the gas tank and I ordered the only one autozone had and it’s the 23gal. If mine came with the 18 gal will this 23gal fit? edit: fuel tank size Link to comment Share on other sites More sharing options...

Pete M Posted November 14, 2019 Share Posted November 14, 2019 If I remember right, the 23 goes in, but will have an extra strap involved. but I haven't done it myself, so wait for confirmation from someone else before pulling the trigger.

I already bought the tank when I got it in the mail was when I questioned myself. The tank in the Jeep had 3 straps already Link to comment Share on other sites More sharing options...
fiatslug87 Posted November 14, 2019 Share Posted November 14, 2019 '86 were only long bed, so the 23 gallon will fit, if you have a 16 g tank the sender will be different. Link to comment Share on other sites More sharing options...
Eagle Posted November 14, 2019 Share Posted November 14, 2019 1986 only had the longbed, so the 23-gallon tank is correct. The 18-gallon tank is for the shortbed, which didn't come until the 1987 model year. Link to comment Share on other sites More sharing options...
fiatslug87 Posted November 15, 2019 Share Posted November 15, 2019 Interesting the parts manual also lists a 16 gallon for the '86 MJ. Link to comment Share on other sites More sharing options...
Pete M Posted November 15, 2019 Share Posted November 15, 2019 the 23 and 16 are longbed. 18 is shortbed. Link to comment Share on other sites More sharing options...
krustyballer16 Posted November 15, 2019 Share Posted November 15, 2019 the 23 and 16 are longbed. 18 is shortbed. Correct. My 86 had a 16 for the 2.5. Wasnt the 23 more ccommon in the 2.8?Sent from my SM-G973U using Tapatalk Link to comment Share on other sites More sharing options...
Eagle Posted November 15, 2019 Share Posted November 15, 2019 The 16-gallon tank for the longbeds is the same, 3-strap tank as the 23-gallon tank. It has internal baffles to stop filling at 16-gallons. It was used on the base models with small tires to keep the gross vehicle weight down. AMC did the same thing with the Cherokee.

Notice in the parts diagram above, both the 16- and 23-gallon tank take (2) #9 straps and (1) #11 rear strap. Link to comment Share on other sites More sharing options...

I was just trying to make sure because The old one is crumbling from rust so I was going to rhino line the outside of this new one before putting it in Link to comment Share on other sites More sharing options...

I bought the straps from autozone and I got a 29.5” and a 32.5” strap (idk why autozone only sells sets of 2 but I tried putting them on since I got the tank out and the new one. But I couldn’t get either to fit in the back same size tank but the straps were both too short. Link to comment Share on other sites More sharing options...
