Fuel Line Leaking

Post by TrashMan » Sat Oct 24, 2020 5:38 pm

What’s the secret to using the felt washers? I replaced the old copper fuel line with a steel line. I ordered new pack nuts and felt washers. Got it all together turn the fuel on and both nuts was leaking gas. It’s my first time using the washers. I put the nut on the line then a washer, used a small screw driver to pack it in the nut enough to start the threads then tightened it down. Is that the right way? Do I have to take it off and start over with a new washer?

Felt comes in all sots of densities. Perhaps the new ones are less dense than required. Some add sealant of some sort to help with making a fuel tight joint. I go a different route, cutting a 3/8" long piece of modern fuel hose, removing the outer layer down to the woven reinforcing, and sliding the inner piece over the fuel pipe. That makes a perfect seal when the packnut is wound up.

Hope this helps.

I use a short piece of neoprene hose in place of the felt and have had no problems. It can be used over without replacement. It doesn't show so no one except those of you who read this will know!

I add a few drops of oil to the felt before placement. Seems to work. I do not have any leaks. Others have used soap from a soap dish. Rumor is that that will work as well.

What Norm said. Ditch the felt and use little bits of hose.

Make sure the fuel line is fitted fully into the fitting, then snug up the nut. I have had very few problems using the felts and I cut mine down some before using them, so maybe I am getting a better crush. ;)
I know the voices aren't real but damn they have some good ideas! :shock:

What Steve and Norm said, ditch the felts. A no brainer as far as I'm concerned, the rubber fuel line replacement "gaskets" are available and the the cut off ones that Steve describes are great too. Why mess with the felts. JMHO Dave

I never used the felt packing until recently. I don't know what took me so long! When I was younger I used to find NOS fuel line nuts with the felt packing installed. Haven't had a problem.

No problem with felt here. Keep cinching 'em down til the dripping stops. If you run out of thread, use more felt. Many old timers got by with string. If you use pieces of hose, be sure it's fuel grade.
