NEED PARTS

I have a Jandy SHPM 1.5 Ser: R09FE0523.  I would like to replace the inard seals, as I’m having any issue building pressure.  When I shut down my pump and open it up to clean everything, I’m having an issue when I restart the pump.  It doesn’t suck enough to get the pump working properly.  If I pull the lid back off and put the hose in to fill it up, it primes it enough; however, I need to replace the seals so I get a better suction.
