Polaris 3900 Sport Feeder Hose Connector / Vacuum Tube Feed Pipe Connection

Pesh · Apr 8, 2025

I love my 3900 Sport but recently the feed hose has been disconnecting from the vacuum tube / feed pipe assembly. I have replaced the feeder hose connector but still having this issue. The feed pipe looks like in good shape with no visible cracks / chips / defects and the factory o-ring is still in place.

Whenever, I connect the feed hose to the Polaris 3900 Sport, it no longer “clicks” and does not make a good connection.

What could be the issue? How can I remedy this?

If all the ball bearings that actually grab the feedpipe are there, it is most likely that the feedpipe is worn out, the ledged the bearings grab is worn out and not large enough to allow the connector to stay in place. Have only seen it once, but it does happen. The part is about $30.00.

If the machine is older, look into getting a complete rebuild kit on Amazon for about $165.00. That is OEM, not aftermarket. Entire bottom half of the machine minus the tires and the two wheels on one side.

I didnt know there were ball bearings in the feed hose connector. Regardless, it is brand new. I have ordered a new feed pipe and i can test fit the connector to the pipe before installing it to see if that solves the problem.
