The fuel filter is mounted behind the transfer case. The fuel pump is infront of the transfer case, not visible in that picture. The hose out of the filter runs the frame rail toward the front, where the fuel pump is. The plumbing was rather simple. The hardest thing to track down was the fittings that go into the Dahl. It's a #10 o-ring boss--I think it's a #10. I called Bob at DieselSite (where I got the filter) and he was able to send me the fittings I needed. It goes down to a 1/4" female NPT. From there it was just a matter of a couple of elbows, a Tee, a 1/4" to 1/8" bushing for the guage, a couple of NPT male/male fittings, a couple of hose barbs, and fuel hose. The hose is run from the stock steel supply line before the pump, to the filter, and back to the fuel pump, making sure there are no tight bends in the fuel hose. I'll try to get a pic of the hose connections at the fuel pump and put it in my "Extra Filteration" gallery this weekend or early next week.

The Motorguard is much cheaper in the long run AND filters sub-micron. Visit
the filtration section of the BITOG forum. These filters are popular with the military and mariners. Why?

Most of the stuff I take off on mods, I have saved. That's one fitting that I knew was never going back on.

Yep me too. That gets rid of one of the air leaks in the fuel system. I did pretty much same install on my 99, Only I used a Raycor filter and the fuel hose is the stuff that you use for Fuel Injection hoses. It's a little beefier and dosen't rot out like regular fuel hose. LPR
