i have a problem if somecan help me. I just bought a 92 F150 ext cab with dual tanks. 1. what are the sizes of each tank and how much do they hold Gas. 2. I just filled the rear end tank but in the gauge it only shows that is half full why. HEELLLLLPPPPPP?

 

I wonder if you have to hat common problem with the tanks leaking into each other because the switching valve goes bad.

I believe there is a kit to switch away from that, but keep both tanks.

Maybe someone will chime in about that.
