Hey guys, merry Christmas.
Man some snow would be cool. You know for the jmonster.
Any way have any of you guys had to replace your fuel filler lines on your J trucks. I went to by one and no body has one of the preformed variety, so I thought I would get a universal one. Man is this stuff high dollar! I got the wrong size of course, just eyeballed it. It seems that the neck on the cap is smaller than the neck on the fuel tank. Does any one have a fix for this that might stop the trial and error method. Its very cold out and I would like to get it right the first time. ( or second time as the case may be)
If you are happy stay that way...if not get that is to short not to.

Merry Christmas to you and your family!

I just did this last week. Nothing out there, and couldnt find any NOS. However, i did buy a couple feet each of 1 1/4" and 1" fuel line and it worked. The metal filler neck has two nipples, and the tank also has two, but the factory in their infinite wisdom, designed the tank connections to be wider than the filler neck. Never mind, by using a good quality hose clamp, you can get the hose to tighten on the nipples satisfactorily. While at the hose store, pick up a foot of spring wrap to keep the big hose from kinking as it makes its bend up to the filler neck from the tank.

I spose you could bend up some appropriate pipe or tube and just use rubber "couplings" at each end to keep from kinking.

I'm gonna have to do something similiar real soon. mine leak out the gas all over the pavement if you fill the tank up to hose filler height.

The filler neck on older J-trucks is one of those parts made out of "un-obtanium". One way to get around it is to take your old filler neck to a custom exhaust shop and have them bend you a new neck out of metal. Then, you just need 2 short sections of appropriate-diameter fuel hose at either end to secure the tube. I've been able to find this large-diameter fuel hose at some speed shops.

The large diameter fuel hose is available from Napa (online) I think it's part #1055 2-1/4" fuel filler. It ran $16.89 or something like that I bought some last week. You'll get a 3' length.
