Hi Glenn, This is what you do. Permatex makes a high temp sealant # 59235. Use this it works. Let it dry for at least a day or two before you run it with gas. Bob

They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I ran into that issue last year when I was putting my T/A together. My lines were leaking like crazy at the carbs, and nothing seemed to help, until my engine builder told me to put some grease on the threads before installing the lines. I never thought that would work, but was running out of ideas. Greased the threads up with red grease, installed and tightened them, fired up the engine, and dry as a bone!

The seal takes place between the inverted tubing flare and the corresponding "male" flare in the fitting. If you have done the "loosen / tighten" routine more than 3 or more times, 1. Either the flare on the tube is bad, 2. The nut is bad, 3. The "seat" in the fitting is bad, 4. Or there is debris preventing the seal. Disassemble, inspect the flare on the tube and seat in the fitting. Your problem should become apparent.

I never thought that would work, but was running out of ideas. Greased the threads up with red grease, installed and tightened them, fired up the engine, and dry as a bone! Grease or oil is best and should always be used on flare fittings to allow you to get them tight. IMO never use teflon tape anywhere on a fuel system, never. Because it is near impossible to get all the little pieces out when you take it apart. Plus it looks like sh!t and tells everyone you don't understand flare fittings.

Since theres inverted flares on these , the threads dont Really hold any pressure Listen to Mr Bill 62 maxwagon This is the proper way - if you cant titen them properly
Generally the use of copper is avoided with gasoline use, as the gasoline with slowly dissolution the copper and actually "plate" the fuel system/carbs/etc with copper thru an electroless process

I will provide my solution to the "leaking lines" on a 6-pack. I resorted to using a small black O-ring that was just small enough to fit inside the Carburetor nut (it the same diameter as the flared fuel line) that the fuel line bolts to. Because the O-ring is actually sealing against the fuel line "flare" and the Carb nut, you can't tighten it real tight like you normally would or it will destroy the O-ring. I tightened it "extra snug". I did this as a "last resort" when I couldn't get my new lines to seal. It has been 2 years since this fix and I haven't had to touch them and they are not leaking.
