Changing out the Fuel/Water Separator Filter on MF7

I first posted this in the MaxxForce engine forum with no luck. I hoping that by increasing the audience size I might have better luck.

Trying to finish up a full service on my MF 7. This is the first time I've attempted this. I've got everything done, including an oil change, with the exception of the FWSF. I opened the drain cock on the bottom of the Filter unit and it seemed like one heck of a lot of fuel coming out. Not what I was expecting, so I closed it up and thought I would check out here before I went further. I was expecting some fuel but it really seemed like I was draining the fuel tank. Maybe I stopped to soon, but it really did seem to want to continue with no let up in flow. How much should I expect?
I have the secondary filter changed already.

Thanks,
Stewart

Stewart mine will flow like that also because it is siphoning fuel out of the tank. Since it is easy to open up the compartment where my tank is I disconnect the fuel line from the top of the tank. It has a easy disconnect and that breaks the siphon.

Thanks Mike, that's what I thought was happening. I hadn't thought of disconnecting the fuel line. But how do you stop the fuel from draining out of the tank? or am I missing something? I have no idea, at this point, where my fuel exits the tank.

What a horrible design, you would think there would be a shut off prior to the canister.

My fuel line attaches to a fitting on top of the fuel tank which is probably what yours does. It is a quick disconnect and all I do is squeeze two plastic tabs, one on either side and it pulls right off.

Thanks Mike. I'll try that another day.
