I'm in the process of designing an auxillary fuel tank to be mounted on the bed. I've sourced a tank and was curious to see what folks have been using for a transfer pump to feed the main tank. I was going to feed the main tank via a "T" in the vent hose on the filler neck. Also possible is the idea of making it a redundant fuel system to supply the VP44 in an emergency situation. I currently have the stock LP in the stock location until the warrentee expires next month. I have a Vulcan relocation kit ready to go after that. Anyone else have a set up like this?
