Tripower fuel lines leaking
Looking for advise on getting tripower fuel connections to not leak. Have tried several times and still leaking.
Carbs loose on studs Light oil on tube ends reduce friction with tube nut Tweak tube bends until tubes fit all the way into carb fitting and tube nut will hand thread snug. Then tighten with wrench just a bit more. Tried brass cone washers. Take apart and try again. Tried again with new tubes and fittings. |

Never had one leak, but always use new lines and new fittings.

First loosen some then tighten some back and forth a couple of times to seat the tube at cone and then tighten some more the last time.
Never fails. |

It''s not real common, but I have seen the flares crack. The crack is so fine you had to remove the lines and inspect them very carefully to see the crack.
I'm not saying this is it, but if all else fails you could have a cracked flare. The more common problem is as has already been said. You need to tighten and loosen the fittings to seat them, especially new lines. Stainless lines, it's almost a given that you're going to have to repeat the ritual. The harder the material of course the less malleable it is and getting the seats to mate takes more time and effort. |

Once the lines have been overtightened, with the flares flattened, the copper washers that Tom S mentioned do the trick. You said yours are new, however. The double flares have quite good ability to seal, even with misalignment. You didn't mention if you're using stainless steel lines. The ones from Inline Tube are not bent correctly to fit. They are next to impossible to stop leaks. The factory used only aluminum and a small percentage used steel lines.
