[quote="terrylamar"]Well, the first sign it was out of fuel, was that the engine shut down. Out of fuel as in the engine wasn't getting fuel.

"out of fuel" generally indicates that the level is too low

There was fuel in the tanks. Whether it was being sent to the engine is another question.

here's some important info that was left out of the original post

Once both filters were replaced, and they were dirty.

cotton swab test??? how did you determine that the fuel filters were dirty... appearance alone?

fuel inlet restriction is the test that will tell you the serviceability of your fuel filters

Priming them was as simple as filling the filter with diesel before it was installed and filling the water seperator with fuel through the small cap at the top. The engine ran fine after they were changed. Far beyond the fuel that primed them. Perhaps there wasn't enough fuel in the tanks and it began to suck air and the engine stopped.

perhaps

I don't know, why would it then run afterward just fine?

becuase it is no longer sucking air... did you add fuel to the tanks? did it die as the fuel was sloshing around under vehicle movement?

I'm not a mechanic and I don't play one on TV.[/quote

that's probably why you're asking ;0)

 

fuel filters on hd diesels don't often cause enough restriction to stall the engine due to the fact that they are changed on a regular schedule... if you notice power recovery and fuel mileage benefits each time you do your annual fuel filter change, it's possible that they should be changed more frequently

 

I just replace my filters and cleaned the strainer. I only had this truck since March, and all the filters looked somewhat new. I had been running on flat land mostly. But when I started going on trips that had long grades and was loaded I started notice a loss of power. The first was a loss of turbo boost for a given engine RPM. It was like having a govener and it was cutting the fuel. It got so bad I was wondering if I was going to make my delivery. After I dropped the load and was I the way home I had no real problem empy. Sure enough I replace the filter and cleand the striner. And no more problems.

 

ANNUAL? Damn!

 

I am a Company Driver. I don't have much say when and what is done, although on my last PM I mentioned that the air filters were dirty and they replaced them. Recently, I had a hose that rotted out. I guess that should have been replaced during the PM and wasn't. I am figuring out perhaps I should take a more proactive approach. What I need is a list of things that should be done during PM. So I can make sure they are being done.

I am still having problems with my fuel mileage. It is still going down. I made a concerted effort at improving it with progressive shifting and watching my speed. It was improving, but the last couple of weeks it has been going down again. I haven't noticed any change in my driving style and I haven't been running that many hills and mountains or carrying particularly heavy loads. I'm wondering what may be causing the decrease in fuel mileage?
