On vehicles with dual tanks, the front tank is the main and the rear tank is the auxiliary. The main fuel balance pump supplies fuel to the fuel injection unit. The low pressure, about 32 kPa (7 psi) fuel balance pump is used only to transfer fuel from the auxiliary tank to the main tank in order to balance the fuel levels in both tanks. As the main tank level drops to about 25 percent below the level in the auxiliary tank, the fuel sender and balance module energizes the fuel pump relay. This pumps the fuel from the auxiliary tank to the main tank. When the level in the main tank reaches a level slightly higher than the level in the auxiliary tank, or the auxiliary tank is empty, the module de-energizes the balance pump relay and fuel pump. Any malfunction in either of the fuel gauge circuits will disable the system and the fuel will not be transferred from the auxiliary fuel tank to the main fuel tank.

I need the wiring diagram on a 1986 Chevy silver ado dual fuel tanks
i don't think GM offered dual tanks on their late model trucks, but you could order a larger (34gal) than stock tank (22gal) with a longbed.
dual tanks 15gal each
Yes, 1 pump per tank.
I owned a 91 Chevy pick up dual. Got it used and the glove box sticker stated that the dual tank option was a dealer installed item.
It has whatever size tanks it was ordered with. It could have dual 60 gallon tanks, dual 100 gallon tanks, dual 120 gallon tanks, dual 150 gallon tanks, etc.
They go as far as they're required to..... if u are talking about range between fill ups it varies. average over the road trucks get 5 to 7 mpg and usually have dual 100 gallon fuel tanks, although some trucks have dual 120 gal. or 150 gal. tanks. Trucks can only use about 90% of the fuel in the tanks before sloshing lets the pickup get air so on average 180 gal. at 6mpg would get a truck 1080 miles between fill ups
None. Semi trucks use diesel, not gasoline. Most have dual tanks, and are fueled from both sides.
Twenty gallons per tank.
in the tanks
any one that was ordered. The campers special was made in the 70's. Also Dually's can have them. The Kodiak is a semi style that has them also.
