Fuel filler hose- what to use??

Why do you need it, Eric? Can't you loosen the clamps and buy a little more length?

Well... I put everything back together and I noticed the filler neck was short of mounting back up to the fuel bezel. Couldn't really figure out what had changed. Tried loosening the clamps, but I couldn't budge them. And OF COURSE all this was discovered AFTER reconnecting all gas/vapor lines and remounting the tank!!! So i figured that I might have to cut the OEM off at the tank, then remove the neck, and reassemble with a new 1/2" longer (roughly) hose. Since then and after rethinking things trying to figure out why things were fine before but different (I thought) now I remembered the BL and how it streches the hose. So today i streched the hose, threaded the screws, and got it back together like it was.

FWIW though... It does take a special fuel specific hose. Napa carries some, not sure it will work though. Quadratec and 4wd carries direct replacements for about $15-$20 plus shipping.

The normal practice with a 2" or longer BL is to furnish a section of steel tubing that matches the inside diameter of the filler neck hose, plus two hose clamps. This keeps the compatibility with stock parts, while solving the problem. However, for a 1" or 1.25" BL, it should not be necessary to extend the hose. I installed my JKS 1.25" BL without a second thought years ago - took one look, and decided it was fine, and have had no trouble in 5 years of use.

Yea mine is a JKS 1.25 BL also. When I installed it I never messed with the fuel filler or anything, left it connected like usual. I just easily and carefully jacked the body up just enough to fit the pucks in there. It never gave me any issues (still doesn't). But only until now, when I disconnected it, did I realize how streched it is/was. Not a ton, maybe a 1/2'-5/8" is all that was needed to get it to mount up. I just wasnt expecting it I guess and wasnt sure if the plastic bezel would handle that amount of pull on it. Finally after confirming that nothing is out of whack or installed incorrectly did I remember the BL and that it does that to the fuel filler.
