Fuel/vacuum diagrams

[jenerek]

Was wondering if anyone had a diagram for duel fuel tank set up. Hoses and electrical. My rig currently has bolts in every vacuum hose that I can see. Nothing attached to carbon filter canister and all the fuel lines are gone.
Its a 1985 scottsdale 2wd stepside dual tank with a 305
