hi i am new here i have a 87 chevy c10 2wheel drive with dual tanks i cant get it to switch tanks only the passenger side tank works but it leaks fuel how can i eliminate the passenger side tank and run it only on the drivers side

 

You have to bypass the tank switcher under the truck I can't remember what they call it and just hook it up like a normal tank. I would not take it out I would figure out why it doesn't switch my guess would be the thing I mentioned earlier. My 83 has dual tanks and I love them.
