    whats typical cause of dual tanks switching and fuel guage not working ? nice shape 79 K20
    is there anyone who has had any of those problems on their truck and actually found the cause(s) ? probably worn out switching valve assembly,

    one tank is full of gas, fileld recently but it isnt using that tank,

    thanks

    Randy,

    Make sure the switching valve is working and check the fuel tank selector switch. It could be a broken wire in the harness or a bad connection or ground.
