The vendor catalogues sell felt to go inside the fuel line nut that is drawn down on the carb. and tank sediment bulb.
Is the felt enough or should I put that little beveled compression fitting on it instead?
Thank you in advance. Bob
Will work better.
Use the felt. It's all you need. Just make sure the inside of the nut is clean.
That neoprene piece will be kinder to the metal fuel line than the compression fitting would be.
The felt works great with ordinary hand SOAP. Just work some soap into it. (the scum from the bottom of the soap dish works well). Ordinary bar soap can also be used to temporarily seal a gas tank and anything else where gasoline is involved.
The soaped up felt is the kindest think (and is factory correct) for the fuel line!!
I never thought of using soap on the felt, but I'm sure it wouldn't hurt. I've (almost) always used the plain felt, and it has worked fine. I say almost always because I tried some rubber grommets a couple of times but went back to the felts. "If it ain't broke, don't fix it."
I used felt on mine and after about 8 years it's still fine. As suggested above, be sure everything is clean first. I didn't think of using a little soap, but is sounds like a good idea.
