Thanks all. I tried some of the electrical wire pull liquid yesterday but it didn't work all that good. I don't have a source close by for the Power Tune. Tried Dawn dishwashing soap full strength and managed to get the fuel fill line to go through but still with a lot of effort. Once in, there is just not enough room to run the vent tube and ground wire in the 3 inch drain pipe I used for the fuel fill. So, I put in a 2 inch drain pipe to run the vent tube and ground wire. I didn't want to run electrical wires in the same pipe as fuel or the vent line so I also ran a third 2 inch drain pipe for the 1/2 inch water line from the fresh water tank (on the port side) to the galley (starboard side), pump wires, a 12 volt circuit to the port side, 12 volt lighting circuit for the port side cabin lights, and sending unit wires from the gas tank. Getting to be a plumbing project.
