I have a 2006 Sprinter van with a 2.7 turbo diesel. I'm interested in installing a Frantz by pass filter. Not sure were to pick up and return the oil. Any one on this forum install a by pass on a Sprinter?
The bypass I put in my car years ago takes oil from the oil pressure sender (i put a "T" in there) and returns it to the pan via a purchased adapter that replaces the drain plug.
Knowing what I know now, i wouldn't bother with a gas engine; your vehicle may justify it;
Waste of time and money. Follow a logical maintenance plan and the engine will not quit. A texting teenage girl will total your van before you ever see a return.
Teeing off the pressure sender port is good, but make sure your kit contains a restrictor in the line leading to the Frantz. This limits the bypass flow to prevent oil starvation in the engine.
I prefer to route the return through the oil fill cap because it makes taking oil samples so easy. If you're installing a bypass filter then you also want to consider oil sampling.
