I have a 91 ultra classic with a rusty tank. I have used the three part tank liner kit with great success in the past. My concern is the interconnect tubes and how to keep the epoxy from sealing them closed. I was thinking of placing a piece of copper wire in the tube and before it sets up removing the wire. Or at least spinning the wire. The tubes have a 90 degree turn to them so it would be difficult to put anything other then something flexible in there. Any suggesstions would be greatly apperciated. This might sound stupid but are those interconnect tubes necessary or does the fuel make it's way over to the other side during normal riding anyway. When I removed the tank to flush it,the interconnect tubes were clogged with debris anyway. So who knows. Thanx for the help. Bus Driver.
