hope this helps.. good luck

If you are using fuel injection with an in tank pump, the GM11C for short bed or the GM1C for a long bed is a preferred tank as it has a baffle around the pump to help keep fuel at the pump when the level is low.

Otherwise for a regular carb set up, the GM1B tank is the one for the long bed.
