I bought a new gas tank several months ago for my 56 Nomad but havent been able to install it because of ....well stuff. I had removed the old original tank several times and patched it and sealed it but it finally needed to go. I didn't have any issues dropping it as before but putting the new one in ............oh my goodness. After a few modifications with a 2x4 and hammer, it was in.(no mods were done anywhere close to the tank inlet only at the top of the tank..and it doesn't even show ha ha) Now it looks like my gas tank filler tube shrunk a bit. I can't for the life of me get the filler tube all the way inside the tank inlet. At the 8-10 o'clock position, the O ring on the filler neck is partly exposed. Any body else had this issue? I am pretty sure I can grind some of filler tube mounting bracket off that is close to and mounts on the frame but I'm not sure that is going to be enough to get the filler neck inside the tank. How far in does the filler neck need to be inside the tank inlet?

Thanks

You need to grease the o-ring before you install it, I use Vaseline or white lithium grease. If not greased the o-ring tends to pop off the filler tube while you're trying to install it. It doesn't fit very far in, the o-ring should seat inside the tank opening.

Craig,

Thanks for the reply. I did the lube up before the install and the O ring is still on the filler tube and hasn't rolled up. It just seems as though the inlet on the tank or the filler tube isn't long enough.

I've dropped and reinstalled this Nomad tank twice before and had no issues. I've also dropped and reinstalled (2) other 57 Chevy wagon tanks and didn't have this issue. The only difference is this is a brand spanking new tank.

Check and see if its installed too far to the passenger side. Loosen the straps and wedge the tank over to the drivers side as much as possible. Has your filler tube a rubber hose on it ? Maybe be pipe went too far into the hose. Do you have the correct "o" ring. Just a few things to throw at you since I don't know the history.

Thanks. I did loosen the tank up from the straps and sending unit to have plenty of play. I have the filler tube loose as a goose and have checked the O ring still not going in enough.

Thanks

Grease the inside of the inlet on the tank itself, I put more grease there than I do on the o-ring.

If you get grease under the o-ring on the filler tube neck it will slide up when you're trying to install it.

My take; My new tank filler opening seems to not have the correct intercept angle to make the fill pipe and "O" ring happy. I have had seeps. Tried grease to help seat the "O" ring but a aircraft product called "Fuel Lube" seems to be far better as it's impervious to gasoline and still very slippery. Just my two cents!

My tank came from classic Ind. and it went in just fine. No problems at all.
