I have an older, 1982 Pace Arrow I need to know which fuel tank is the MAIN tank; the front or the rear tank? John, (Placerville, CA)
John, the main fuel container on that vintage Fleetwood motorhome is usually the one located between the main frame rails. Typically Pace Arrow had one tank between the rails and one tank located outboard of the main frame on one side or the other. The floor plan dictates the tank locations, however, and if yours has both tanks between the frame rails, look for the tank with the rounded edges, probably the one mounted closest to the rear of the motorhome. The AUX tank usually always had square corners while the main container will have rounded corners and edges. The other way is to locate the electric switchover solenoid valve (usually located inside the front right frame rail), and follow the fuel lines back towards the tanks. The inlet port on that switchover valve that is “in line” with the outlet port is the one fed from the main tank. That said, all the above should help you unless someone has modified the original installation.
