I have the same valve, from the same e-bay seller. No problem with the valve. I have mine hooked up to the ignition switch so when I turn it on oil starts to flow to pre-lube, no dry starts. Bob what's with the 40 lbs. I think the instructions say about 12-15lbs., can't remember right now. I know it will hold 65lbs. for at least 2 months. As you said,a accumilator is the only way to go. Saved my engine last year when the pressure relief valve suck and lost pressure.
