Don"t know what book you are reading but the hydraulic pressure has never been over 3000 psi. Normally on an FMD it should be 2000-2100 psi at 1200 rpm with a new pump.

Have you tried shimming the unload valve?

The pumps are no longer available, you have to fit a Super Major pump with a right angle elbow adaptor, a pump will cost 600 and an adaptor is like hens teeth, very rare.

Thanks, I miss read the manual it was talking about a pressure gauge for testing. the manual does say (pargh 231 system relief pressure adjustments) if using heavier implements it is permissible to increase the pressure relief setting to 2500-2700 PSI. yes I tried shimming the unload valve and got 100PSI more, then when I added more shims it started going back down. Has any one ever rebuilt one of these pumps. I am a retired aerospace engineer and I also restore old cars and have made parts before.
