fuel line

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

If this is a stock 40 Ford gas tank the only pipe threads on this tank are the drain plug threads.
The filler pipe is not a pipe thread. The fuel line is not a pipe thread. It is sealed with a compression ferrule.
So the only place to use sealer is on the drain plug.

D'ya suppose the MESS above could have been avoided by simply asking " should I use some type of sealant on the drain plug threads on my 40 Ford gas tank " ? Most folks would not refer to the drain plug as a "fitting that goes to into the gas tank" . The one clear bit of info from the poster of this thread simply states "40 ford" & it was correctly pointed out that a 40 ford only has a plug - NOT a "fitting" or a "shutoff valve" . The thread was-is not about 32 trucks . If you wanna be the top bananna start your own thread . Also snipping at Bruce Lancaster falls into the bad idea category with me as he is probably one of the most knowledgeable contributers here . HEY RYAN !!!!! I would cast a vote to get rid of this mess of a thread .
 
Drain plug and not the fuel line?? THAT was a touch unclear! He's in luck, though, as 99% of the things won't come out without using nuclear weapons...he's miles ahead if he needs info on putting it back in!
 
Last time for me. Pipe dope on pipe threads (optional). No dope on any other fuel line fittings, no matter what kind of vehicle. Compression or even flare seal at the compression or the flare, not the threads. How did this get so far?
 
Damn right! I wish someone had put pipe dope on all of my Ford drainplugs 80 years ago.
The progress towards the actual question reminds me of the threads that start something like "I have a flathead. How do I fix the carburetor?" AAAAAAH!
How many electrons have died in vain!

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.

Right on Sonny .I'm a licensed Master Plumber and a licensed Master Mechanical Gas Fitter and still working .:cool:

Bruce, Not only are you one of the most knowledgeable fellows out there and seemingly always willing to help, you have a refreshing sense of humor!
 
Well I just read through this for the first time today because I couldn't see how such a simple question could go on for three pages. I thought maybe the subject had changed to the meaning of life. LOL
Now I'm adding to it.
 
Maybe for all of us it is a lesson in how to ask a question clearly, without leaving out essential details or over embellishing the facts.
In my background (automotive engineering - development) you have to know how to clearly phrase a question.

Im sorry my question was so difficult, and that i'm not an engineer just an OLD MAN trying his best to put this old Ford back together, but for those that asked ; it does say at the subject matter that it is for a" fuel line" i'll admit i did forget to say it was for a 1940 Ford.
 
While i'm being "Lambasted" i might as well ask another dumb question. Does anyone know what the purpose of the spring on the installation of the fuel tank, ""ON A 1940 FORD""
 
Sorry, Hope, I was not criticising you. You did exactly the right thing. You asked a question and got the answer.

Hope the rest of the re-build goes well.

Ok here's my take on the spring. It is to allow some frame flex (lots of un-paved roads back in the day) without transmitting that flex through to the tank. Radiators are mounted with a spring for the same reason.

Don't be sorry Hope ,you just asked a simple question and got a few different answers .Happens quite often .Take it with a grain of salt .Sorry I don't know the answer to your last question about the spring:confused: .I'm sure someone knows it and will answer it for you .Hang loose
 
isn't funny how a simple question can be turned around so much, to make it sound stupid by some a....
