2003 Dodge - rough idle and water in fuel light on

[cdslguy]

I recently ordered an Extreme Power Puck from Xtreme Diesel and after installing it on my 2003 Dodge 2500 the truck ran rough at idle and was noticeable louder (loud knocking). As well as the water in fuel light came on and would not go off. I unplugged the puck and the light went off and ran like normal. Hope i can get some help with this!

Did you double check that you hooked it up right and did not invert any of the connectors?
You will get some serious rattle if you do not hook it up properly, I would double check that and if all that checks out it might be the wrong part number and or a compromised unit.
