fuel line

[sonny]

What part of understand don't you understand. I don't recall anybody saying to use any kind of sealant on the ferrule.

 

[G.M.]

There was discussion several years ago about the Ford fuel fittings supplied by Royal Brass and copper that had ferrules attached to the nut. These ferrules were hard to compress and could cause a leak if not pulled up real hard. After thinking about it I think they were made of 1/2 hard brass and should have been annealed so they would easly compress. G.M.

I think we are all talking about different types of applications here. Gas shut off valve (pipe thread) screwed into tank, dope optional. Gas line to said shut off valve,ferrule and nut, no dope. Air line for gauge at tank, no dope but ferrule is soldered to line. Capasci?

What type of sealant do i put on the threads to the fitting that goes to into the fuel thank?

Thanks

I was under the impression that the fitting screws into the fuel tank ,this was based on the question being asked .

 

[sonny]

The shut off valve is that fitting.

No shutoff valve on a 40 Ford. The only pipe thread would be the drain plug.

Guys I think he is talking about the PIPE THREADS into the tank. Use Teflon paste. Teflon paste is a lubricant and not a sealant for tightening and releasing. Wipe it clean if you are doing a 100 PT. car. Pipe threads are tapered and should seal themselves. AMEN

x2 on the pipe threads sealing themselves

I always use some type of sealer on pipe threads .Just because the threads are tapered doesn't mean they will seal themselves .Geezs ,I been doing it wrong for 43 years.Try putting water lines or gas lines together without some type of sealer and see what happens .The threads are tapered ,but they need some type of sealer .

 

[sonny]

I agree with Joe Plumber. just for safety sake on pipe threads I always use a little pipe dope. P.S. Did I mention I'm a retired licensed plumber.

 

[Gumpy]

no sealant ....i would recommend not tighting it too tight or cranking it down if your ferrel is brass with i think it is...good luck

WOW i really opened-up a "can-of-worms".

 

[sonny]

Hope, not a problem. Just remember pipe thread is the only fitting that you would use dope on, and that's optional.

 

[Bruce Lancaster]

But there still aren't any pipe threads involving stock fuel line...connections are all compression ferrules with straight-threaded "Ford nuts"...

 

[sonny]

Ho Hum.

 

[Old Henry]

WOW i really opened-up a "can-of-worms".

Or, was that a can of "pipe dopes?"
