1967 390 hp stainless steel pump to carb fuel line and master cylinder distribution

[Dave K.]

The SS (stainless steel) pump to carb line leaks at the fuel pump and the SS master cylinder distribution lines also leak at the distribution block. I can NOT get these lines to stop leaking. Would going to a steel line be better and get a better seal?

Dave,
Many have experienced the same issues as you are having with stainless steel lines. They are extremely hard and the flares on the ends of the lines don't want to cooperate very well. The standard steel lines are much more forgiving. To your question, though, try loosening the fitting and tightening down again, and again, and again using flare wrenches ONLY. With enough patience and some luck you may be able to conform the fittings where they will seal for you. Best of luck.

As I've mentioned many times previously, I'm a guy that LOVES stainless steel ANYTHING. I would rather wear a stainless steel watch than a gold watch. However, I do not recommend stainless steel for fuel lines or brake lines for the exact reason you have discovered. Besides, fuel lines suffer from very little corrosion damage and the TBW lines are quite durable.

And, new TBW fuel or brake lines are going to last longer than ANY of us are ever going to need them to last.

They do make copper flare savers to help with sealing lines.

I agree. Here is a link to have them delivered in one day. If you have a Grainger's nearby, they should have them, as well.
