Hey every one. Is there a good budget solution for adding a pree filter some where on the OBS trucks before the factory fuel filter. Other then the filter being kind of small I question its ability to filter properly after seeing all the junk in the fuel pressure regulator screen. I was kind of thinking about adding a large fleet guard filter under the truck some where and using it as the primary filter. I would love to add a air dog system but this is a budget truck for now.

 

There is no reason to add another filter on a stock system. Drain the fuel bowl from time to time, replace the filter at proper intervals and you'll be fine. As far as the air dog system, it's expensive and hard to come by on the road. Better off going with a Napa/Wix setup (if you go e fuel) or a Baldwin filter setup. Your budget will thank you.

 

I'm pretty sure the FPR screen is on the "raw" side of the filter. Raw fuel outside the filter, clean fuel inside. So gunk on the FPR screen is not indicative of filter performance.

 

I got a filter head and electric pump off a 1660 IH combine years ago and installed in on the frame rail just after the tank selector valve. The spin on water trap filters for it are $16 and I thought the micron rating was 10 or 12.

after I installed that I never had to change the factory filter I just changed the cheaper easier spin on filter.

I'll find a pic and post it in a lil while.

I installed this set-up on my '97 way back in 2007, in early 2012 I ran it on my crew cab for a few months then in April 2012 I put it on the Reg Cab when I did my WVO conversion, which is when I took the pics. The pusher pump is the same pump that was on it when I pulled the unit off in the Junk Yard. The combine was a mid-late 80's model and its entirely possible that is the orignal pump.

All I did was pull the rubber line coming off the front of the selector valve and run it over the frame to the suction side of the pump, then I ran the red hose from the output side of the filter to the steel line on the fram rail. it took my longer to run the wires and find a keyed power source then it did to drill the holes in the frame and hook up the hoses. The factory fuel bowl and 2-stage pump are still in the valley, fully operational. The pusher pump shown only puts out 5-7 PSI. As long as the small hole on the inside of the fuel bowl is open this pusher pump wont hurt anything on the factory system.
