Unde the gas tank on my 74 cars, are 10mm fittings on the tank with a 10mm fuel line through the center tunnel. I think I should use 9mm fuel line but cannot find any source. What should I use and where to get it?

I couldn't find it. I used a US spec size...

How much you want? I have a meter or so, and can get more. I'm sure HPH stocks it, as well. The Cap'n

I need a meter, enough for 2 cars under the tank. Can you send it to me and how would you like payment?

Thanks John!

I used 3/8".......let the flames begin. Works good and I can find it at any FLAPS.

I did use 7mm for the smaller line if that counts
