View Full Version : Fuel Filter Question....

10-04-2010, 05:52 PM
Just bought 2 new Mann fuel filters part no. WK 820/1 for our 2008 3500 chassied V6 Winnebago rv. These filters have no water sensor connection or O-rings in the box.
There are 2 Mann part no.s shown for this application. 1 with sensor and 1 without. Our unit has the water sensor capability, but I thought the filters were cartridge style. This is a sealed cannister with 2 hose connections. Part no. checked out for this unit.
What did I get here?

Your fuel filter should look like this. Pretty sure what you have is a no go.

That's what I thought. It's the same except it doesn't have the water sensor connection in the center.
So I guess I'll send them back!

Thanks for the quick reply!!
