Intermittant fuel leak

[Mikie12]

I have my 100 gal AUX fuel tank in the bed set up for gravity feed. I ran a 1/2 inch hose from a ball valve through the oval hole in the front of the bed down to the vent hose located between the filler neck and the tank. Spliced in a brass "T" and hose clapped it.

I usually leave the valve in the open position, and fill when I need to from the AUX tank. I notice sometimes I'll have a drip or two on the drive way, but not all the time. Maybe a few drips per month. I looked on top of the tank, and noticed that it was damp where the hoses and wires enter the tank through a round opening.

Is this anything to worry about? Is it normal? Is something wrong with the seal at the top of the tank? Am I going to come out one morning and find a hundred and thirty five gallons of fuel running down the street?

Has anyone had any experience with this?

Thanks, M.

Are you sure it's coming from where the hose and wires come out of the tank? It could be coming from either the front roll over valve or the rear one and running to that spot before dripping. I would say it happens right about the time your bed tank goes empty and the bottom tank is full while your driving the fuel is sloasing around causing the valve to seal and unseal creating a small leak.
