Default Venting the gas tank 1940 P.U.

I'm installing a "Tanks" gas tank on my 1940 pickup. At first I thought I would simply attach a vent line to a vent fitting/opening that is available on top of the new tank. But since it is a pickup, I find nowhere to run the vent hose that is high enough to keep from leaking out splashed gas. In a car you can run it up inside the trunk wall. Any ideas for a pickup?

If I stick with the original gas filler tube as a vent, does the cap still use a gasket? Thanks Barners.

If you are running rear enders, I've run a brake-vent line up and around in the wheel well opening, using the attaching fender-to-bed bolts as attach points. I've done this in my 40 coupe and it works better than without it at fillup time.

If you are using the plastic 40 tank the vent location should be up inside the left rear fender.The vent needs to be higher than the tank. I make a bracket to attach to a fender bolt and then mount the vent/rollover valve to the bracket. When you mentioned people venting the tank up inside the trunk wall I hope you didn't mean venting the tank inside the trunk. That's just plain unsafe.
