on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Jun 2006 Posts: 74 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2006 Posts: 74 | I have a 56 TF that I moved the tank to under the bed. Stainless steel gas lines run along the frame to the engine compartment. I have two brass in-line connectors that are leaking fuel. I've tighten both up, but still have less of a leak. So progress, but not the total solution.
Do these connectors require Teflon? Is there something I might be missing here? Gas eating through an o-ring...???
The garage is a bit randy with the smell of gas. Momma's tolerating it... for now.
Suggestions welcome. | | | | | Joined: Aug 2010 Posts: 255 'Bolter | | 'Bolter Joined: Aug 2010 Posts: 255 | Check out Permatex - they have a sealant for fuel lines. | | | | | Joined: Oct 2010 Posts: 171 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2010 Posts: 171 | I have two brass in-line connectors that are leaking fuel. are they compression or flare fittings?

Is there a way to tell without unscrewing the fittings? It would be a mess! | | | | | Joined: Jun 2009 Posts: 2,201 Shop Shark | | Shop Shark Joined: Jun 2009 Posts: 2,201 | If it's still leaking, you gotta take it apart anyway.  Are you from Colorado? Or is the truck from Colorado?

Most brass fiting are compression fitting, not all, If it is compression try giving it a 1/4 turn and see if that does it, if not then another 1/4 turn. if that dont do it get an empty gas can and a new full length of tube, drain the tank and pitch the fitting.

54barnfind - That photo is the brake line. I'll give the fittings another turn to see if that makes a difference. Thanks!!
