Took the kids to an amusement park and they had a fire engine on display on the inside door jamb they had the capacities listed pretty interesting.

What does it say on top of that knob/ cap?
It appears to say "Guess" with the last "s" covered by the remnants of a sticker, so not exactly a reassuring thing to place on a cap, or a switch which it also might be lol.

I’ll try to get back to double check still at the park…
 
Guest for air ride seat? Long shot.
We also had a few trucks where, if that is entering the front seat, the master electrical switch was about there.

For those wondering the pump primer oil lubricates a rotary vane pump that pulls vacuum on the fire pump to prime it. This is used when sucking water from a portable dump tank, pond or stream. Most fire pumps are not self priming hence the need for a separate primer pump.
 
Most of our new trucks are 11 gallons for oil or more . Some take 15 or more gallons of coolant also.
