[C320-list] Fuel pump

[Jerry's Iphone]

Another question from a mechanically challenged guy who loves to sail. 
I had a dock mechanic winterize the boat last winter. He told me that there seemed to be too much water in the fuel and suggested fuel polishing. I had a local marine service do it. After starting the boat last week for the first time, it ran for a while then cut off and would not restart. Dock mechanic checked it and said it’s the fuel pump that probably got gunked up from the polishing. He said we’ll need a new one. I’m starting to wonder if he knows what he’s doing, or possibly if his advice is self serving. 

Any and all wisdom you have to share is appreciated.
