Re: dual fuel tanks

My dad had thought about doing a second tank on my '74 K20 years before I got it from him. His plan was to use an electric fuel pump but he never go past the scheming stage.

Re: dual fuel tanks

Run it like the factory, just get the tank and sending unit and wire in the switching valve, The pump will pull it out just like the other side.
