"hose hooked to the riser?" What does that mean? You shouldn't be connecting a hose directly, but rather using a bucket of water for the pump inlet. The vane pumps can pick up only a few feet of head and should self prime.
What pump? You could have a Sherwood or an Oberdorfer. If it's the latter, check the faceplate - it needs to be smooth. The inside of the faceplates gets gouged over time and either need to be replaced or serviced to flat.
