Chevrolet Repair: fuel system, ash tray, gas tanks

Question
i have an 87 chevy 4x4 i was wondering if their was more than one switch to the gas tanks ?

Answer
Hi Mike,
If you are talking about the rocker switch by the ash tray, there are a couple different ones.
One, you just push one way or the other, and it is there.
The other, when switching tanks, you must flip it, but then hold the end down for a second.
