Fuel filler tube connection

[tthoms]

I had my tank cleaned, and in the process of putting it back the tube that connects the filler tube to the tank refused to fit. It looks like the PO overtorqed the clamp ring and deformed it.
I found a replacement on Aircooled.net, but the description throws me.
http://vwparts.aircooled.net/Fuel-Filler-Neck-Hose-Inner-Seal-113-201-215-p/113-201-215.htm

Its labeled as an inner seal, while the tube that I removed went around the fill tube and the fuel tank opening (it reminds me of radiator hose). Have I identified the wrong part, or did someone put the wrong part on before me? Any ideas on a fix?

Thanks in advance!

Pictures???

That part goes on the steel gas tube, right behind the barb. Then the filler hose slides over that ring to further seal vapor release.

Check out this page.

It has a diagram for the parts. Part 33 is the inner seal you have a link to., in your post.

Here's a picture of the tube that I removed:

It doesn't look like the set up you referred to from Wolfsberg.

Bummer.

[VW_Jimbo]

That is the number 34 part.

The part you referencd before was 33, which goes in each end on that hose.

I did buy new ones for mine and they were too short. So, I over tighten the clamps and guess what, they stretched out. Made that inner rubber band make sense. No leaks for over a year now. Time will tell if I got it figured out.

seems like as good a time as any to ask this, but is there a reason you can't use one long hose to go from the fuel fill door to the tank? I never really understood the need to use 2 pieces of rubber, 4 seals and a metal pipe when you could possibly just use one big rubber hose. Would eliminate a few points of failure in terms of vapor leaks.

Maybe use some fuel fill tubing from kartek or something.

[busman78]

Gates 23930 or Dayco 80305, 1-7/8" fuel hose (48mm), runs about $45 for a three foot stick.

You can also get rid of the plastic adapter that has the vacuum hose attachment if you no longer use it by using a single length of 19/32" PCV hose.

So, to recap, the replacement hoses from Wolfsberg are the ones to get, or are they too small? I've placed my order already....

My 73 has two tubes and in the middle a metal elbow. The filler hole fits on to one tube and the end of that tube fits to the elbow. The elbow then fits onto the other tube and the end of that tube fits onto the tank.

The old tubes has this tiny extra piece of rubber that fit inside the tube and helped seal it up. I didn't use it on the new ones. The tubes should be hard to put on otherwise you might not have the right size. Clamp them up and you are good to go. Fill the tank all the way (top it off) and you will know if it leaks. Carry a fire extinguisher just in case.

So I recieved the inner bands and the replacement tube from Wolfsberg West. Comparing the new tube with the old one, I noticed a problem.

I double checked the part number, and according to the website, the new part is the "correct" one. I didn't feel like cutting into it, so with the new bands, I made the old one work.

I also added a rubber fitting to the filler tube opening. It doesn't fit quite right, but that could be personal ineptitude on my part.

I've put a gallon in, and I'll see what happens tomorrow after the battery charges.

Put the new tube in a vise and take a hacksaw and cut very slowly. The slow race wins here. Even a wood saw will work. These are not banded with metal.

The issue with your old tube is, if you take it off and look, the ends will be cracked. I can see the age from the cloth band around it. You either replace it now or soon. It's really up to you. Probably with the new bands you were able to tighten it down a bit more. You really won't see any issues until the gas is sloshing around in the tank and some of it sits next to the entry so it times to work it's ways through the cracks.

Hello, I recently bought two of the hoses and cut each to juuussst over half to make both sided of the metal elbow. I used a exacto knife to make a clean, easy cut. No leaks.

When I first replaced those hoses on my 69, they came from WW as 2 separate ribbed hoses. They lasted about 10 years before I started smelling fuel and changed them again. This time WW sent that single hose that you have to cut in half. Works fine and no more fuel smell.

Sounds like I have an appointment with a hacksaw. The old tube is holding for now. I'm going to have to disassemble the whole gas tank assembly to repaint the inside of the bonnet in about 6 months. I'll make the change then.

[VW_Jimbo]

Yes, you need to cut that hose in half. Easy with a utility knife with a NEW blade. Wrap a piece of masking tape around the outside as a reference line to cut to.

Change that old hose. The hose fails from the inside out. After you have replaced it, cut it in half lenght wise and bend it against its inside curve. You will see the fissures that are present and soon will leak, with our highly aggressive fuels out in the marketplace.
