Ive got a leak in the fuel line on my '62 TR4 on the tank end section. Where can I pick up a section to replace or is this a special order?

If the leak is in the tube you can cut out the section of metal tubing and replace it with 5/16" metal brake line tubing. Connect it to the old tubing using short sections of rubber tubing (like the ones that come w/Fram fuel filters.) If it's the fitting, its harder as they are NLA and some have had trouble using new ends.

the leak section (about 2") is at one of the bends in the line. Do you think it would be ok to cut it out and replace/bridge section with 5/16" rubber fuel hose, clamped on each side?

yup. go for it. TR3 has some rubber at the bends in that area anyway. Just visualize how anything might hit that area or flex and use common sense.

For what it's worth, I had a similar leak many years ago in my GT6+. I discovered it when about to head home from Kmart, where I worked at the time. I ended up actually cutting the line where it was leaking, slipped some rubber hose over both sections, used some small clamps to make sure all was snug...and never thought about it again.

If you have a leak in your steel fuel line in one spot, doesn't it concern you that the whole line is on it's way out. When I restored my TR6 (and on my previous TR6, and, on my previous TR3) I found that the entire line was pretty crudded up. Not necessarily rusted (in some areas it was quite thinned out) but clogged, bigtime. One technique is to use a very long piece of tach cable and rout out the line with the end of the cable attached to a drill. Now, if the line is thinned out too much, this is not a good idea. Why not just go to NAPA and buy all new 5/16" steel fuel line and make up all new fuel delivery lines? Several of the joints are indeed often rubber (make sure that you only use designated as "fuel line", otherwise you will be asking for touble - usually Gates brand is dependable), using the self-tighening clamps, instead of the screw type, which will come undone and cause leaks. Now, if you car is a concours winner and you are worried about the perfect bend, etc., then often fuel lines come from vendors already made up, but you will have to dig deep.

Good luck.
