Got a new Truck (new to me)

You can take the TBI pump out of the modular assembly that drops into the tank and plumb a piece of fuel line in its place to drop into the bottom of the well of unit. Add a sock filter to the bottom. Helped do this before on several of the TBI trucks.

Sounds like a good idea, use the Original Gas Tank and Keep the Original Gas Gauge when switching over to manual fuel pump setup.
