New motor huh? They come factory wired for 220 volt. If your electrical at the pump is 110 that will definitely cause the motor to surge and ebb, giving you those pressure readings as it tries to kick into high gear, but can't. If you are normally running 110 there( test it to make sure) and didn't switch the wiring over inside the motor, turn off the power, remove the back motor cover and compare the wiring with the diagram on the top label of the motor. It's all colour coded, with the exception being the black tracer, it's white and black. It's usually a simple matter of either moving a wire or two or in the case of a hayward, moving a white terminal block from 220 to 110. It's clearly marked. As this is a new motor, I'll bet this is the issue.
The only other things that would cause the symptoms you're describing, is cavitation in the suction line somewhere. Either an object caught in a line (unhook your cleaner if you have one) or it's possible that the pump impellor is jammed up with small debris that made it past the pump basket. Also, it's possible, but unlikely, that during pump reassembly the diffuser plate was incorrectly installed. They usually only fit in one way and it would be difficult to get it in there improperly without some sort of leak happening, so this is a long shot.
I see a lot of people in here claiming it's the filter. Nope. I can garantee that the filter has nothing to do with the symptoms you're describing. In fact, it will have nothing to do with ANY equipment or plumbing line, past the filter pump.

question is, how old is the whole pump?
it soundslike you wanted to save money so you got a new pump and gaskets for it.
filters only last about 3-4 years now and when they go its just best to buy a whole new filter.
we had one that just got replaced...the new gaskets would not seal or anything and the sun started getting to the plastic along with all the chems. from the pool.
we went from the earth filter to a sand one as its easier to backwash

Low water level coming into skimmers --- air leak in pipes --blockage -- trap full/sucking air around seal. Try to "backflush" the filter and start with it clean.

The filter may have a problem causing the fluctuation in pressure. I have filter cartridges and I know when they need to be cleaned, that happens.

donno what this so called "expert" commented on, saying the motor comes wired for 220 volts....well in my part of the country this is MOST certainly NOT true! Motors for this use are always wired for 110 volts, unless you order specifically, and then would need to spend even more in electrical to run it.....as far as the disconnects and all...GFCI< etc... my guess is skimmer water intake fluctuating? or does this happen when pool is calm?

Add a pressure regulator to the water supply.
