2nd Gen RX7

Is it 5/8 for main and return and 3/8 for vent?

I can't seem to locate this information anywhere and I get to replumb my lines. (And I have no old lines)

Thanks in Advance

I believe they are 5/16" fuel injection lines.

I'll be redoing my lines also on my vert.

Remember to make sure they are for fuel injection only, there is a difference.

Wow that is TINY. I bought some aluminum hard line from Summit. They claimed it was good for 120 PSI or something like that.

I need to replumb my car because my factory lines run down the inside frame rail near the exhaust (plus they are a little smaller than I'd like). (It's in a Sidekick not a Rx7)

Both are 5/16". I replaced my fuel hoses yesterday. The one that go to the canister from tank vent is more little. I think is less that 1/4", but I'm not sure.

Excellent Thank You!

I'll have my motor together this weekend... Damn Torque wrench broke... so I have to wait until tomorrow to finish it.
