I've been having problems with my truck as I have posted in a couple of other posts. I think I found my problem today. I took off the FPR and disassembled it and this is what I found.

This is the reglator disassembled


This is the port where you would typically do the FPR mod. Notice the black pieces of what seems to be some kind of plastic material.


This is looking down into the strainer that is in the bowl on the bottom of the regulator.


It was hard to photo all the debris in the last photo so I held the strainer up to the light and here is that photo. Notice that the part furtherest away from my hand you can't see any light through it. That is how full of crap it is.


This photo is looking up into the bottom where the strainer goes on and the bowl screws on over the strainer.


This truck only has 156000 miles on it and the fuel filter looked like crap. I guess the person that I bought it from just wasn't as honest about the maintenance as I thought.

I will have this all cleaned up and back on the truck later today and I will report back on how things are going.

Thanks for all the help and support that I have gotten from everyone here on my issues.

 

nice find! hope it helps the truck run better!

accually from looking at that old rubber fuel line. you may just want to go the extra mile and take out the fuel bowl and replace all of those rubber fuel lines. when i did that to mine it helped the truck run a little better it seemed.
just my .02 cents.

Nice post gave ya some rep points for that one. Found a couple black chunks in mine when i did the FPR shim. Probably should clean mine. Cheap fix. About all I can afford now anyway. Bored to death with this winter crap.

 

good stuff. hope all goes well for you. dont forget to check the condition of the fuel heater while the fuel filter is out.

 

UPDATE.....Truck prrrrsssss like a kitten now. Idles smooth, accels smooth, and no surging, no dieing when coming back down to idle as in slowing to make a turn etc. The plunger in the port where you do the FPR mod was stuck in there pretty good, so I guess the fuel wasn't really getting regulated. I've had this thing for a couple of months now and I thought it ran well when I got it, now I really think it runs well. It's dang smooth on the throttle now. Thanks for all the help.

 

guys with '96 and '97 trucks. notice where that long black piece is on his FPR??? that unscrews and then theres that little screen filter in there. if you pull your FPR off in that same spot as his last picture its got a snap ring and you pull that "plug?" outta there and there is a little filter in there too. it looks like steel wool just stuft down there. don't know how often they get dirty though. took the one on my dad's '97 apart with 147k miles and that piece wasn't dirty, but the FPR screen was filthy!!!

 

Nice work. Great pics of that early FPR. I was wondering one looked like on the inside. Probably one of the most ignored parts of the fuel system on these rigs. Reps sent!

 

mines coming off this weekend then any special o rings or anything to put it all back together?

 

New o rings would be a good idea. Diesel o rings or NAS has kits.

 

I checked with ford and they didn't carry anything at all. You can purchase the whole regulator or just the oring that goes between the regulator and the filter housing, the screen that goes in the same place. No aftermarket store like advance, autozone, or oreilys have anything at all. I was able to re-use all as they were in good shape, but looking at the debris inside it has to be from the insides of fuel lines comeing apart like was stated by 79f-250 above.

But, the truck is running sweeter than it has since I got it.

 

does the round black strainer cover screw out or is it pryed out. i pulled my fuel filter
housing/regulator assembly to look for cracks. i want to clean everything before
installing. thanx for any help 96 f250 ps steve in north carolina
