Are you wanting instruction for removing the whole fuel filter assembly to look for the lost part? Or just instructions for installing the regulator kit?

I'm trying to figure out what's going on, but this post and the one in 99-03 have very different information.

 

The selector valve on the 94-97 is a six port design. It has seperate feed and returns for each tank.

 

That's what I was thinking, thanks for the confirm.

 

Does it smoke when it starts running poorly? Any abnormally loud noises? Check engine light?

I don't understand how it could contine load up the filter to the point that it won't run after you switched to the clean tank. Have you check the oil level in the high pressure reservoir, or had a look at the wiring harness connectors at the valvecovers.

Did you find all the parts to the regulator?

I hope my merging your threads into this single thread isn't viewed as a lack of compassion, that was not my intent. It's simply that the fuel pump and fuel control unit on the OBS trucks are suffuiciently different from the 99+ that I think this thread has to be in this forum to get an accurate diagnosis.

 

ok this is my second time typing this same info here goes.

its possible the selector body is clogged. meaning you may flick the switch but if it's gummed up and not moving inside fuel will still be coming from dirty tank. if thats how they work...not to sure.
a few things i would do.

1.buy the fpr kit from ford tommorrow. you may have 60psi at idle but without the ball under load who knows.
2.after your done installing that. empty fuel bowl. fill with diesel kleen.
3. put a serious amount of diesel kleen in "known good tank". 1+ bottles will be fine. never can have enough of this stuff.
4. put selector switch to known good tank. even though it selected doesnt mean fuel is coming from there if piston inside selctor cant move.
5.if still running rough after all this. drive to a parts store who has a quality code reader. see what you got.
6. you may wanna clear pcm now for the heck of it. disconnect both batt's for 10 min with headlight switch on. pcm will reset.
7.if all else fails go to ford i guess.
8. i dont know north dakota very well but here are a few guys from tds that are on the help network. if unfamiliar with that.. basically they got tools, knowledge, psd's, and are willing to help. i have no idea if they are close to you or not but here goes.
9. if i wasn't in florida and there i would love to help ya. good luck sorry your vacation is ending up like this.

Thanks for all the answers. I'll try to respond to what's going on. Cookie, no I didn't find that 'little ball'. It doesn't blow smoke at all, even when the check engine light comes on. That's the funny thing, its not loading up the filter but if I put a jug under, open the value, start it, it will fill the jug and have junk in the bottom. Today I took it all apart again and like BBjack said, sprayed wd40 in the pump. Put a pop bottle in the valley while my wife cranked the engine and it filled the 16 ounce bottle half full in about 12 turns of the motor. The fuel was clean this time. Kwik, I cleaned the tank switch over value, don't think its that. What I'm starting to think is that the pump is weak and needs to be changed. I have a inline pump for that auz tank, I'm thinking about expermenting by putting that pump in the supply line ahead of the tank switcher to help the one on the motor. Probably a bad idea but when your stuck, any thing is worth a try. Cookie, I understand the forum switch, I was just trying to get some of the orginal OBS owners to chime in who have a newer truck now. Like I said, when your stranded, you'll try any thing. BBJack, I'm thinking now that you have hit the nail on the head about that little ball. Sounds like it has to be in there for the pressure. My guage shows a steady 60psi though. Again, confused!!!!1

 

i doubt you have a fuel pump problem...
reason being you are seeing 60 psi at idle no ball.and you are pumping plenty of fuel out of it it sounds llike.buy the ball. i think that is the issue now. once you put a load on her you need the ball to maintain pressure. try checking it while wife revs truck up. although while parked its hardly a load but worth a try.

 

I'm digging through the manual trying to figure what in the fuel system can turn on the CEL....but I'm not having much luck.

I really beginning to wonder if it's a short in the injector wiring harness.

 

So am I cookie, my wife's sisters son said the same thing. He said he would bet money on it being the value cover wiring harness. That ball sounds like a real problem also. 1997F-350, thanks so much for that information. If I can't figure it out soon I'll call them. We have a little trail bike on the back of the 5er, I'll get to town to Ford's for the ball and value cover gaskets. Or, do auto parts stores sell them? I wish now I had a set off of ebay. Does anybody know how to tell what side it is before I pull them off? I suppose when its running rough and pulling the plugs the motor should die.

 

it just splits the return at the selector. sends return back to the tank its taking from.

the fuel pump isnt something i would take off and clean and put back in. its not the most fun project and the pump is about $80 gotta have a 10mm and a 1 1/4 wrench and a blade screwdriver. with that kinda fuel pressure it makes me think the pump is still working. is is smoking alot when its runnign crappy? dosnt have any top end power?

yeah i meant just buy the regulator kit with just the little parts in it not the entire regualtor.

filter housing removal.
unplug the ipr. unplug the plug on the passanger side of the fuel bowl. remove 2 lines that feed heads. remove return line. remove 2 bolts holding the bowl down. remove hose clamp on line thats going out of the fuel pump. and out she comes.

 

i was gone today...didnt hit the refresh for i posted....


so running bad what exactly is it doing?

 

Parts places will not have the gasket. You can pull the connectors at the valve covers prior to removal and check the connectors for burnt pins, might tell you which side is bad (if that's the problem). Unhook the batteries....the injectors are high voltage.

 

Thanks again everybody. Tommorrow will be a new day. Also, if I just bought one value cover gasket, can it go on either side or is there a right and a left?

 

valve cover gasket will work for either side. not too sure how much time you got where you are at but if you got a burnt plug external that plugs into vc gasket you gotta go to ih for plug repair kit or pay ford 400+ for complete harness. pull the plugs externally first. see what you got there. if it is the outer most pin on either side of the plug no biggy they just go to the glow plugs. you can still get home with those burnt. now if it is any of the middle 3 you need to worry. in my link in signature i have pics of all the parts you would need including prices and places to get them. since on you are on vacation i would use ford and ih for parts sourcing only. ok anyways if you see nothing burnt externally pull the vc's and see what you got. if burnt under there new parts are in order. like uvc harnesses and gaskets.



can you please tell us how your truck is running. if it will start. can you drive it. what is exactly going on. only running on one bank. what?????? i have used uvc harnesses, gaskets and parts for external plug repair. you got an address i can overnight too???? please keep one thing in mind tomorrow is a holiday(monday) dont know what will be open.

if you need anything

 

1997F-350, that's quit generous. The truck starts, runs fine for a minute then it craps out for a minute or so. It feels like its only running on one bank unless its still a fuel problem. I can drive it a little bit, like today I drove it for a block to get some water for the 5er. Sure glad we have the camper with us. Tommorrow I'll check the three inter pins on all four plugs. What is uvc, something value cover? So what your saying, if I have some burnt pins the wiring harness might be screwed up? Well, I'll let you know, Thanks so much.
