woodsplitter hydraulics problem

I have just welded up a wood splitter. fired her up, and the pump doesn't seem to be pumping hydraulic fluid. I called the pump manufacturer, and they blamed mis - matching manufacturer parts. He gave me no help on my problem. I have an 8hp Tecumseh motor (3600 rpm), an 11gpm pump(3700 rpm max) and a 2500 psi logsplitter detent valve. I have a 5 gallon fluid tank, and a 24" long stroke, 4" diameter hydraulic cylinder. Do I have to prime the pump, valve, and cylinder. Does the valve have to be mounted flat, or does it make any difference? (mine is mounted vertically) Help!

I just realized that I mounted the pump with a pulley running below the pump. This would mean that the pump would be driven backwards (counter clockwise) . I will cut the bracket I fabricated and remount the pump. Will let you know if this works

After re - mounting the pump, I still don't have pressure, although fluid seems to be getting to the valve, as I had a small leak. Could I have ruined the pump running it backwards for a bit? The cylinder ram was extended from its inward position, and is now in this position. Should it have been shoved back in, or shouldn't this make a difference, given the detent valve?
