Is there such a product out there that one can use to line a 3/4 drain line. My new to me boat had a leak coming from the front live well. I've removed the live well and replaced all the plumbing that I can access, but there is one 10' section of tubing that runs under the fuel tank that I'm unable to access. I've confirmed that the 3/4 line is leaking. I'm guessing this section of tubing is glued in with the spray foam or pinched by the fuel tank. Removing the fuel tank would be a bear of a job being I would have to remove my rear livewell and a couple of bulkheads. I've tried pulling a new drain line next to the existing hose but there is not enough room. So that said is there anything common out there for a repair to this like a hose liner?
