I replaced the hard line section that runs along the back of the transmission, against the cockpit step, that runs from the gas tank vent rubber line
on driver side to the short rubber line that connects to the carbon canister on the frame under the passenger seat. I used a 51 inch nicopp preflared
5/16 brake line tube hoping to use the flare to help hold the clamp on, but the flares made the connection too big so I cut two inches off both ends
and just radiator clamped the rubber tubing back on. This replaced an original looking 46 inch steel tube that I discovered clogged shut with rust for
the second time in five years. I had the front wheels off and liners out and the job was much easier. There were three support connections shared with
the passenger front brake line. Two on frame, and one that connected brake to vent line behind transmission. This line is essential for proper tank
venting (filling, temp changes, using the gas). You can check for flow in this line by removing top hose from check valve in driver rear wheel well or
at hard line under driver seat, and the connection at the charcoal canister, gently apply air and have a helper listen for flow. Just putting it out
there as a reminder to check, as well as possible parts solution.
