I'm getting ready to try and decipher the pump. I'm willing to enlist all the help I can get, so I'm putting a diagram of the pump panel up on the site. My hope is that kind-hearted folks can help me determine the following:
1. What sequence of operations will allow me to test the pump?
2. How can I test suction?
Here's the panel:

Here's the labelling:
1 - "Vacuum"
2 - "Oil"
3 - "Temp"
4 - "Pressure"
(not labelled - Tank level and RPM)
5 - "Relief Valve Control"
6 - "Left Rear Discharge" (on top of truck bed 1.5")
7 - "Right Rear Discharge" (on top of truck bed 1.5")
8 - "Throttle"
8A - Unlabeled thing between 8 & 9, no obvious function
9 - "Prime - Hold Down"
10* - Open/Close
11 - "Reel" - Open/Close
12* - Outlet
13 - "Fill Tank" - Open/Close
14 - "Manual Prime"
15 - "Manual Prime"
16* - Big Outlet
16A - (unseen) "Drain"
17* - "Cooling"
18 - "Suction"
19 - "Tank Suction"
20 - "Drain"

* - 10,12,16,17 are replicated on the other side of the truck.
Two outlets are on top of the truck bed (Rear discharge)

Thanks for any help!! Mail me with ideas
