Was riding the trusty ol' John Deere this evening and make a lap around the Ram and what's this??? I see a puddle underneath and smell the fuel. I've been having some trouble w/my aux. fuel tank wanting to fill my main tank lately and just thought that some crud from the aux tank had plugged the filter. A quick jiggle of the valve has worked the last couple of times. I did this on the way home tonite and when I worked the valve a couple of times, it immediately filled the main tank back up to full. On to the problem.
I look around under the truck and it's not leaking anywhere around my plumbing or fill neck splice and it's coming from a small open vent like nozzle on the top of the tank near the back. I've read that these tanks have un-capped vents but what would be causing my fuel to fill it up that much to run out there? I popped the gas cap on the main tank thinking it would have to be full up to there to cause it to leak out of the vent but I can't even see fuel in the filler neck.
Am I doomed to not being able to gravity feed my main tank all the time and just when it's empty? Not a big hassle but the first tank full (51gal. ) worked like a charm and I never touched it. Or can I just cap that vent? There is an anti-flow ball valve where my aux. line tees into the filler line that I thought was supposed to close when the main tank filled up to that point. Could some trash be causing it to stick open?
Any help or suggestions greatly appreciated.
