here is a pic of my installed filter, anything jump out?
My DFuser looks about the same. I ran it over the AC line though but that doesn't change anything.I was going to link in pics of my hose routing but it is easier to show Sinister's picture. Did mine the same, has been in since last fall.
Installed pic is further down the page on the right. Coolant Filter System for 6.0L Ford Powerstroke - Sinister Diesel
Ok sorry it took a while to get back, i finally had time to re-route my line going from the filter to the heatercore line. The line still lays right acrossy the tac tube where it comes out of the filter. The fitting with the ball valve is not overly tight but comfortably tight, and the valve is on bottom and there is a little twist in that line. I was actually more comfortable with it ont he other side. I can tweak on it and get the twist out i am sure but non the less....i drove it this morning and still puked......GRRRRRRR
Unless the bypass is bypassing a blockage that would otherwise be containing an overpressure situation after the water pump.I still think there's something simple that was done wrong in installation. It's a bypass, the hose could be tied in a knot and still not cause any problems. There's nothing about a bypass that can add pressure to the system.
