Mechanical gas tank selector

[csutter]

Being paranoid about running of gas since my dual gas tanks don't have fuel sending units, I decided to get the right hand tank filled up and see if it worked since I hadn't used it since getting the truck on the road.

To switch tanks I have a mechanical valve in the drivers floorboard. As soon as I moved the valve to the 2nd tank, the valve started leaking gas into my floorboard. Valve probably hasn't been moved in 15 years. I have looked all over online and only see electric switches, can I go to hardware store or similar and just buy a valve of some kind?

Also, I looked under the truck and it has what looks like connections for 3 tanks. 2 are connected to my tanks, but the 3rd has a short piece of pipe that is connected to the valve but loose on the other end. The other end also has what looks like an electrical braid for grounding hanging off of it. Not sure why this is there or what it is supposed to do, I plan on removing it as long as there is no safety or other issue for this to be there.

Thanks for any info!
