So I suspect that you may be hunting for some lost miles per gallon, or perhaps have noticed sluggish performance from your 7.3 Powerstroke. I am going to walk you through locating and cleaning the FPR Screen.

The FPR is designed to maintain the fuel pressure in the cylinder heads at 40 psi. In addition ensuring that the return restrictor doesn't get clogged with grit. It is my understanding that the oring failing and clogging the screen is a myth and rather is gunk from the tank. O-rings are responsible for clogging your spool valve in your FPR, however.


Step 1:


Step 2:

Between step 2 and 3 it is essential that you have a telescoping magnet handy to catch the screen if it falls into the valley (area below the bowl). Mine fell in during install and removal and I retrieved it both times.

Step 3:

Once you have access to the screen you will find this (most likely)


which is the fpr screen covered in a layer of debris.

I have found write ups that suggest using a qtip to clean it, but based upon how tightly packed the gunk was it would be ineffective. When you have the screen out soak it in some break cleaner for roughly 5 minutes. I then scrapped off what I could and then shot it clean with brake cleaner.

Reinstall is simply reverse of removal. I found it helpful on the reinstall to have a screwdriver in my right hand to pry the fpr away from the bowl, use a pair of needle nose to stick the screen in the housing, and then have a screw driver in my left to push it in a bit more.

For the o ring I found it helpful to again pry the fpr away from the fuel bowl and then stick it over the end of a screw driver. I used my finger to block the oring until I got it on the housing it rests on, and then slid it forward. Pushed the housing back into its location and ensured that the oring doesn't get pinched.

As always I declare no responsibility or liability in you breaking something while following my guide.

Just cleaned mine over the weekend. Immediately noticed a pick up in power on the "seat of the pants" meter. I'm hoping I will see an increase in fuel mileage from my, as of now, dismal 11mpg.

I haven't noted an MPG increase I'm getting 12 and I reckon this tank will be the same or less. But that is partially because prior to this mod I noted it cutting out and after this mod (not a mod I guess but don't know what to call it, service procedure I guess). While I noted this cutting out I was running some damn high boost trying to haul *** and get home. After this mod I was running a few 25+ psi runs to see if its fixed or if I had another issue going on. This mod was done the day after this started occuring and it cured it. I've also been idling a lot so I suspect that also hurts my mileage quite a bit. After this mod I too noticed a more pep in the step of the truck, in that I am guessing less fuel is required to maintain the same psi in the injectors.

None the less this service is a must do.

Well maybe my problem is somewhere else then. The near 4.00 per gallon pricetag is good motivation to find the problem though.

Yeah, I don't know if the winter blend is stronger there or if it just affects PSDs more, but I haven't ever noticed a drop of more than 1 mpg with winter fuel in any of my Dodges. Shouldn't these trucks be getting 14-15 mpg or better? That is just based on what I've read on here. I wouldn't think winter fuel would drop mpg's 3-4 points:dunno:

According to people I've talked to they said it drops easily 3-5 points. It is a combination of things however idle times/startup energy, etc. I was shocked at my first fill up of getting 12mpgs, I hope it returns in summer to about 15-16 or so.

I suspect it affects psds more because of the injector setup but that is just a guess. I don't really hear dodge guys complaining all that much about winter fuel they are getting about 15 or so even with winter fuel. I was tempted to look at the mpg gauge on my bosses 05 cummins just to see what he was getting but I didn't.

Be a prudent idea to replace it I'd reckon. That or your tanks are damn pristine.
Yep, mine was just as bad as his. It isn't the tanks I would worry about but the big tanks at fuel stations. Those things are full of crap and the filters on the pumps don't do that great of a job...

So pulled that apart just now. Pretty simple. glad I didnt drain the bowl.....the screen was pretty well stuck to the fpr and rather then fight it or ef it up i just blasted it with brake cleaner...she was pretty gunked up. Going to take her for a spin down to the barn now and see what it see....god i hope i just squeaked a couple mpg's by doing that....

edit: Just took her out for a spin down to the barn and she pretty much feels like a entirely new rig. The throttle response is much better and im sure i just bought myself a couple MPG's just by the feel of it. Sweet

Nice I've pmed a couple of mods and also used the report feature but thus far I haven't seen it added to any tech article. Its really too bad as I had this thread and several other links/books I wanted added. Oh well I guess just keep this thread going.

F5TZ-9A214-A should be what you need.

Also guys it would help out for some proof if you could post mpg numbers before an after. I went from 12.some to 13.48 ( I also had my hubs unlocked second time, and then aired up my tires.) I idled a hell of a lot more second time though.
