55, 56, 57 chevy gas tank filler o ring

Showing how to engineer your own o-ring seal for the gas tank of my 57 Chevy car gas tank filler neck. Using the very same Gates 2 inch ID rubber hose that will connect both of my gas filler tubes together, I realized I forgot to order a o-ring seal. So I cut about 1/4 inch slice off of the round hose and using a little lubricant and dressing The Edge down it will slide into the existing Groove for the O-ring. It cost NOTHING and I can get it done NOW... the original o-ring design is not leak proof to begin with. I found the square edge of the tubing to be a little bit too thick and robust and needed a dressing down with either a belt sander or a bench grinder, being very careful to not grind off too much and careful to get it consistent all the way around. Applying some oil or lubricant makes it very much easier to slide in. This seemed to work for me.

[@billygreer]

is the gas cap behind the tail light on a factory 55 ? My friend said that only the 56 n 57s was like that, so where is the gas cap on a factory 55 bel-air ???????

[@hotrodswoodshed7405]

Your friend is correct. 55 gas cap is divers side with its own door in the rear fender (not hidden)

The hose you have isn't fuel resistant. There is fuel filler hose that is thought.

[@hotrodswoodshed7405]

At this point... 1.5 yrs & 15k miles later, with no leaks.. not even a drop.. im not concerned with fuel resistant hose. Its sealed
