try this one on for size it is a 22 gallon tank from a 1988 chevy
g10 van size is 12 3/8 deep or tall 22 in front to back and 31 in
long or side to side. the sender is in the top and the filler is in the
drivers side toward the rear portion of the tank. the diamater of
the hose is 1.5 in. The stock sender unit for the chevy also has
the 3/4 inch vent to the filler neck. I recently bought one from a
local radiator shop, was a new tank.Radiator Overflow Tank
Thank you very much for this info. Just what I was figuring out just recently. Will add this into my notes. Thanks again.

Watch out on that sending unit; Dodge was one way, GM the other.

In Ford and Chrysler applications, the sending unit increases resistance as the fuel level drops and decreases resistance as the fuel level goes up. When the fuel tank is empty, for example, resistance is high (around 73 ohms). High resistance reduces the current that flows through the fuel gauge, producing little or no movement in the needle. When the fuel tank is full, the sending unit has low resistance (around 8 ohms) so more current flows through the fuel gauge. This heats up the bimetal strip causing maximum needle deflection. Now the needle moves all the way to the full mark.
A shorted sending unit or a short in the wiring between the sending unit and gauge would reduce circuit resistance causing the fuel gauge to read full. And with nothing to slow the amps, the circuit would probably overload and blow a fuse. An open in the sending unit or wiring, on the other hand, would prevent the needle from moving at all and the gauge would read empty.
With General Motors analog resistance fuel gauges, the basic operating principle is the same but electrically opposite. Resistance in the sending unit decreases as the fuel level drops, and increases and the level goes up. When the tank is empty, the sending unit reads about zero ohms, and when the tank is full it reads about 90 ohms. Gauge operation is also the same with maximum needle deflection corresponding to minimum resistance in the sending unit. In this case, maximum deflection is required to move the needle all the way over to the empty mark.
A short in the sending unit or wiring on a GM system would cause the fuel gauge to read empty, therefore, while an open in the sending unit circuit would make the gauge read full.
