Blocked suction filter ?

 

Sometimes there's a filter inside the tank at the outlet.

 

Low oil level would also give your symptoms

See I emptied the oil out of the tank for transporting and it was very slow to come out. Never checked to see if there was a filter.

Incorrect grade of oil or blocked breather ?

you need to strip the pump and check for scoring and wear on the end plates, this will cause cavitation and pulsing , depending on how bad, you might be able to hone it out, if not the pumps probably past it, again as has been said before, check rotation, although the arrow says one thing, its very easy to reverse the rotation of these pumps, and quite often isnt marked on the casings as having been changed, oil, either iso 30 or iso 46 should do, as will any 10w single grade oil, intake pipe work, rew new it as a matter of course, its a cheep fix to many other "problems"
