Fuel line

Line from fuel bowl to carburetor is 1/4 inch. Looking at replacement parts they don’t mention size. Is 1/4 correct or should it be 3/8
 
Here is a trick that I have used to avoid leaks. I use 1/4" steel brake line with brass compression ferrules , but before installing, I position the ferrules on the tube and carefully sweat solder the ferrules to the tube. This helps seal the joint without having to use excessive force on the fitting to compress the ferrules tight to the steel tube.

Replacement lines are readily available from any of the suppliers. They are made from the proper grade of steel, come with the right fittings, and fit perfectly. When working with gas it is always best to do the job right.
 
And don't swallow the pill for the brass screw fitting that has the compression ring attached. I think a lot of gas lines are sold with this fitting as part of the "package."

These are supposed to work by "shearing off" the compression portion and then acting like any other compression fitting. Clue for the clueless - they don't.

In fact, as trouble free and reliable the old fashioned two piece screw nut/compression ring is in real life, for you if you're like me, the combined screw nut probably won't seal - and you'll have a gas leak. And you'l have a gas line from which you can't get the ring OR screw nut off of. As in either cut and shorten the line - or throw it away.

THIS is the fitting you want.

I agree. The fuel line you get from the vendors come with the "shearing off" type that don't work. Snyder's sells the "correct" fittings separately...

The fuel line I got from Mac's had the preferred fittings. Worked great.

Agreed; Just replaced this line with the Mac's line and other than a slight "adjustment to the shape" it was perfect!


I came across a suggestion to put Teflon tape on the ferrules (not the fitting threads) before installing. Anyone do this?

Not necessary, brass is soft and will form to the fitting. If its been removed and overtightened too many times, just replace rather than try to fix it up with a bandaid.

X2 - Teflon is used on pipe thread but never on compression fittings.
 
7 years ago I had to fix a Model A that wouldn't go faster than 30 MPH.
His gas line at the carb was blocked off with Teflon tape.
