Onan Maquis 7000 in 93 Holiday Rambler Fuel Pump Issue

Hello,

I have a problem locating the F2 Fuel Pump fuse on my Onan Marquis 7000 Model # 7NHMFA26106C in my 93 Holiday Rambler
I have replaced the bad pump with new pump, no power on + wire to pump which I suspect is a blown F2 Fuel Pump Fuse.
Unit will start if cranked and spraying fuel down carb throat but no start with pump directly powered.
The Fuel, Ignition and Choke are all on this circuit so I need to locate Fuse to eliminate it as a potential reason.
From Net research it should be in line outside on right of control panel but it isn't.

Any help would be appreciated.

Mike

    Kpackpackkelley,

    Thank you, this helps in a lot of ways funny thing is in this manual it shows the F2 fuse located in the cover of the control panel but on mine cover has nothing other than F1 Fuse and Start Switch.
    Must be a year change thing or something along them lines.

    I we assume it is a Spec D version then Fuse more likely is on back of Air Cleaner adaptor. Guess I am going back out there and see if I can locate it.

    Checked it nothing attached to back of Air Cleaner, guess I will have to trace all the wiring out until I find the fuse, doesn't make sense it would be inaccessible, maybe someone may know where it is located.

    In looking at Schematic Fuse F2 protects the Fuel Pump, K4 Relay and Choke
