1989 Ford Ranger fuel pump location

Engine Mechanical problem
1989 Ford Ranger 4 cyl Two Wheel Drive Manual 84.000 miles

i been told to look on the right inside fender to find the pump relay, but in some manuals it shows the map sensor and the fuel pump mounted on the wall, but on my truck there is power bus mounted on the wall there is no relays there, where else possible could this pump relay be. Thank you for your time. Help
