    Optic sensor filter

    Paveltolz, Nice shot of that filter. It hides on the back side of the injection pump. You need to crawl up on top of your raidiator and look around the back side of the pump. I like pictures also.

    Optic sensor filter

    Just my thoughts on what I plan on doing with my 95 6.5 is I plan on leaving my filter in place and if I have problems I am just going to take it out and see if the problems leaves with the filter. That's just me though. Others have their own opinions on the filter and that is good.

    Optic sensor filter

    Buddy, that is how I understand it also. If you don't have one that is fine. If you are experiencing fishbite then one might want to put one on. Or if you have one installed and experience fishbiting you might want to take it off to see if the fish bite goes away. For the most part they are...

    Optic sensor filter

    Yea, I am not sure if it is needed. I have just been doing alot of reading and I think I did read that. I think I read that if you are having fishbite that it could be caused by a bad filter. I also think I read that it is a Radio Noise Eliminator?

    Buddy, it runs good without the o/s plugged in. Other than you have to spin the motor over acouple of times to get it to start. The codes are there though when it isn't plugged in and service engine light is on. It did always run alot better once the service engine light came on. I have a...

    Hey Guys, Just got in from testing the burb again. I did put the clear hose on the return. I drove it around until it started acting up again. I then checked the hose for bubbles at idle and in drive as I was pushing on the throttle making the engine run rough. There was no bubbles in the...

    Buddy, I searched around for location A and D on the connector. I can't seem to find what pins are what. Can you send me in the right dirction so I know what pins to check for power on the OS? Thanks. I should probably take out that OS filter harness and try running it with that removed...

    Truck Runs Real Rough, Please Help

    Buddy, I have been reading about code 18 and yes it looks like the optic sensor. I can't just replace that? It looks like it is the black cap item on the top of the pump? Or is it more internal? I have been putting in 16 ounces of diesel clean in each 42 gallon tank. Also I have been...

    Well, Here's what I did now. I took it for a test drive and thought I would stop every once in a while, even though it was running okay, and check for codes. I got no codes for a while. Then it started running bad and I stopped and checked for codes. I got Code 18 (Pump Cam Reference Pulse...

    Truck Runs Real Rough, Please Help

    Yes, it does seem like a heat soak issue. Like earlier, after it sat for acouple of days, it ran great for about 20 minutes. Then I shut it off and let it set for 1/2 hour or so and it started running rough as soon as I started it up. An injection pump would act like that?

    Truck Runs Real Rough, Please Help

    Okay, I tracked down a guy that has a 95 pickup and he had his pmd mounted on the fender wall. He came over and we drove my burb around until it got warm and it started running rough again. We then took his pmd off and put it on my burb. Still ran rough. So we eliminated the pmd. I...
