I've got a question about my auxiliary fuel tank. I thought I had my leak fixed, but I apparently didn't. I put fuel in it for the first time Sunday, and after driving home, I realized that I was pouring fuel onto the driveway. Apparently the 1.5" barbed pipe in the filler hose with the barbed 90 for the aux tank fill line, either has a hole worn in it, or the hose itself has a hole worn in it. The aluminum barbed fitting in the filler hose is sitting directly on top of the frame.
In order to replace the hose/fitting, I'll have to drop the fuel tank. From there, I have a few options. Given the aluminum "T" is the problem, I can do away with it and just replace the filler hose from the neck to the tank. If I do that, can I plumb my aux tank into the vent hose that comes up the the top of the filler neck? Or would it be better to cut my new filler hose outside of the frame, so it can be gotten to easier if trouble ever arises again.
The vent hose on the truck doesn't vent to the atmosphere, it's still inside the closed system.
Thanks
