New fuel lines

I just installed new fuel lines on my cj5 :v6: and I want to get some ideas from you guys.

From the tank to the fuel pump. I used some unbent brake lines from the auto parts store.. the factory sizes were 5/16" from the tank, then a 1/4" return line. Well, I used a coupler to hook 2 pieces to make one long line.. I was wondering how should I finalize this install.. should I use any sealant on the fittings/coupler or just tighten it up ? Some locktight, thread sealant ?

I also cut off the ends to hook rubber lines at the fuel pump.. I dont have any tool to make some kind of bubble at the end for the rubber hose to slip over and for the clamp to hold it on well. So, I plan on using 2 hose clamps to secure the rubber line on the hard line.. is this decent or should I do something else.

I've used these type of lines before.. they have a galvanized coating on the tubing.. and then a zinc finish on the fittings. I have seen the zinc fittings rust up pretty quick. What should I do to keep it from doing that.. some paint, primer or ?

 

For the ends I used a brass fitting and double flared the steel line. The brass should seal it tight. On the other end at the pump I just flared the end a little bit to keep the rubber hose and clamp from sliding over the steel line.
If you're concerned about rust, try liquid plastic dip or use some left over undercoating. I have used tar before, anything that is not water permeable.

 

Sliding the hose over the tubing end, with good clamps, has worked well for me. No leaks. NB this is for gasoline, which only has a few psi pressure at most.

 

Treat yourself to a trip to the tool store.A flaring tool should be required eqiupment for DIY tool box . what part of oregon ?

Thanks for the tips.. I borrowed a flaring kit today.. I'm going to use the double flare adapter to push the tubing down and it budges out.. looks like it'll work pretty good.

Mike - I live in Aumsvile.. used to live in Salem, and I work in Salem. I found pics of your CJ on here, it sure is looking pretty good ! I wish I had more time/room/money to work on my Jeep. Mines been sitting for quite a while.. and I work on it every now and then.

Any other ideas about rust on the line/fittings ? I dont like the undercoating idea very much.
