Default JetCat fuel line priming

I am having a problem figuring out how to prime my fuel lines. It is a P-60 with a version 6.0 ECU, I have run the turbine in the plane it is in now, but not for a while. No fuel in the lines now after the fuel valves.
The manual directs me to go to the test-function menu but I can't figure how to access it. I am using the old style GSU that is rectangular and that menu is not available anywhere I can find.

Hold select menu button. Use + (right arrow key) to scroll through menus to Test Functions.
Let go of buttons. First option should be Fuel, press and hold Change Value button and push + again to pump fuel.
If it’s all connected correctly the fuel valve automatically opens and fuel will flow.

Thank you Dave,
I would never have found the menu without your instructions. Missing from my earlier instructions to forward arrow the menu's while holding the select button. Turns out that is quite important to the process.
A further problem has now cropped up in that the plus button only increases the value displayed and does not operate the pump. When I try the start cycle I can hear the pump working, just no fuel past the solenoid valves.
As a plumber I would think I had stuck solenoid valves, but it bothers me I can't get the pump to run in the test cycle. I know it works or at least runs. I have disconnected the electrical connections and reconnected them as I was having troubles with the GSU not reading anything. That seemed to be corrected by some jiggling of the wires.

It’s in every manual I have ever seen back to 1998!?
Sometimes the pump needs jumping with direct 6v power

I blame it on my inability to comprehend and follow simple instructions. I did not read the instructions properly. It seems, I hope, to be a result of an intermittent electrical connection.
I now have the fuel lines primed.
Thank you,
John
