fuel filler pipe seals

[tommylg]

The "rubber band" seals are installed on the pipe prior to fitting the hose.
Question:where exactly do they go on the pipe.


I ask because I have read multiple posts and did not get a definitive answer.
I am considering using 3M Upholstery trim to glue them in place and warm up the hose for ease in application. Sound good?

Happy Tuesday,
Tommy

As I recall there is a flair on the pipe and the bands you speak of would sit against the flair. When I installed the smell kit from WW they were to be installed dry. Since gas is a solvent, I'd think twice before using any type of adhesive to attach those bands. I wouldn't want any kind of goop wicking it way into the fuel tank and fuel lines.

Yes, heat up the hose, but you'll still have to muscle it on. I spent a week one afternoon putting that smell kit on. It's a chore, but worth it ... haven't had a whiff of gas since.

I replaced the two factory big filler hoses on my 1970 back in 2018, did not use any rubber band type seals, and get no smell. This job was tougher than it should be !!!!

Those "fat rubber bands" are the actual sealing membranes. In a late Type 3, they are submerged when the tank is full.

I often had them roll under when I slip the hose over the pipe. I now lube it on the outside with "spa lube" a heat (and gas?) tolerant type of vaseline, and then it doesn't catch and foul the sleeve. Lube the inside of the hard thick hose, too, so it slides on smoothly without friction.

I agree that the "bands" should go on dry, just past the barb.

I found that these giant "radiator hose picks" are the way to get the thick filler hose onto the tank filler.

Use plenty of lubrication and walk the hose on using the pick and lots of muscle.

I heated the bands and the pipe to body seal for about 2 hours on simmer.
I did not use adhesive and misted the pipe w/PB Silicone spray.
All 3 went on pretty easily w/the help of a dull knife.
I placed the bands over the "nubs" and I think I will get a great seal.
The pipe hose is next w/the same process.
Please do not hesitate w/thought or guidance.
Good Wednesday,
Tommy
