Hey guys, I'm looking for a spot to tie into my fuel filler hoses so I can transfer fuel from my aux. fuel tank to my main fuel tank. I have a Cummins electric fuel pump that I'm going to mount under the bed, I just am unsure if I can use the smaller 'vent' hose at the fuel fill neck. I haven't found any diagrams of the fuel hose routing, so I'm not sure. Any info would be greatly appreciated. thanks!
