Where is the fuel pump and reset button on a 1988 dodge b250 van?

The 1988 Dodge B250 doesn't have a fuel pump reset button. Fuel pumps in vehicles of that era are not designed with a resettable component like some modern cars might have for certain fuel delivery errors.

The fuel pump itself is located in the fuel tank, under the vehicle. Accessing it requires dropping the fuel tank, which is a significant job best left to a mechanic unless you have considerable experience working on vehicles. There's no external access point.
