    don't, they should be compression fittings, if they are leaking or something, there is a problem with the fitting and it should be replaced.

    Only use teflon tape on pipe threads. Not on Inverted Flare, AN, or other fittings, those are designed to seal on the flare and not in the threads.
    Leave the first full thread bare of tape. Makes it much harder for a sliver of tape to get into the the system.

    Lately at work I've been using Lock-tite 545 which is a pipe thread sealant. Works great and you don't have to tighten the snot out of the fitting to make it seal. Which a good thing since of those sensors cost more than I make in a month.

    I dont personally like the clear ones. Their filter media is so small.. you'd be changing it often. If you really want a really good non tool removable & replaceable one, try a Racor.

    I don't know if all teflon tape is okay for gas applications, but I did notice the other day some teflon tape at ACE said it was specifically okay for gas.

    I sell it at work myself . Teflon tape for gas lines , is yellow . Its mainly for natural gas , but I assume it would work better in this application as well .

    The first time you have to rip apart a carb or swap out an injector because a small sliver to Teflon tape is clogging it, you'll know why it's a bad idea to use it for fuel lines. Get a filter that doesn't use pipe thread. :rolleyes: Save your Teflon tape for house plumbing. :cool1:
