Hi Folks,

I'm new to the Roadster world, but have restored old american cars and bikes before. I just bought 2 1966 roadsters, with the intention of putting one of them back on the road. I had a question about the brake and fuel hardlines. I would like to replace these with stainless (mainly because I live right by the water) but I can't find a source for them, yet.
They look very simple, and I've fabbed these lines before. Can anyone tell me the specs on the lines (diameter) and the fittings (NPT?). If I can get that I can just make some new ones out of straight tubing.

This SAE engine/metric elsewhere thing is throwing me for a loop...

Thanks a ton.

The hard part has already been done! Classic Tube ( http://www.classictube.com/ ) has the tubes in stainless. They are for the later cars, but I believe that you can use all but one of them. Welcome to the fray!!

For your information, make sure you save your old lines first. Classic Tube is going to want you to send them to them, because when I called them about my 66 they could not find the pattern.

So I ended up doing them myself!!

Yeah I went through that with inline tube on my last project.. a 1951 Chevy 3/4 Ton. I don't know why these vendors say they can make em.. they're always missing one pattern. Do you remember the tubing size? I guess I"ll just get out the gauge...

Thanks!

Welcome Matt,

I am pretty sure the brake lines are standard 3/16ths and most if not all of the fittings are 3/8's x 24. I am guessing at the fuel line but it appears to be 1/4" tubing. There are I believe four fuel line fittings on the fuel line for the early cars. One at the tank, two at a splice underneath the passenger side and one at the fuel filter. Let us know the actual size of the fuel lines when you figure it out.

Will do!

This looks like a great resource for these 311's, was glad to stumble across it.

I whipped out the gauge today and measured the lines... the brake and clutch are 3/16ths and the fittings are 3/8-24. Hope that helps somefolks.
