J Pump W Motor VacFush Duckbill Replacement. How to?

[RobJVA]

All, I am stumped on how do replace the duck bills on my JW vacuum generator. Attached are some picks and the below link is the parts schematic. Simply unsure how to loosing the plumbing to the tank. I have to remove the pump itself to replace duck bills, just not sure that if I loosen the pump, will that be able to slide to allow for the plumbing to be loosed? The JW pump should be on most post 2006 systems. Any help would be greatly appreciated.

Looks like you remove the four screws (marked #8) and then loosen the large nut at the hose attachment on the side of the pump body(marked #1). pump should lift out then unscrew 1 1/2 inch fittings to access the duck bills. Also the 2 duckbills below pump. With the large nut off you shouldn't have to slide to far, not as far as if you try to take the hose off the fitting.

Thank you for the detailed response. It is greatly appreciated. I am in a busy marina, and did not want to get stuck in the middle of a dirty job like this one.
