One of the check balls are not sealing on the down stroke. Check bottom ball on the pump and make sure it is free and no debris in that bottom housing.

Yes they should work, although, the Graco cylinder seals are larger and you really have to stuff them in the ipm’s. Using TSL helps get them put in if you need to.

@@shieldliners thanks for the quick reply yeah I can tell they were a little bit larger than the factory ones but what really caught me off guard is the top spring was visually you could see it wasn’t as wide and it was falling down in It was wanting to fall out that’s why I stopped and I put the original one back in.
