Ya there goes the nieghborhood, it's that place btween Oklahoma and Louisiana.
Might mention to Gunner that there is a lot of information in the tech folder along with pictures and illusrations to fill in the blanks although this thread has covered most of it.

Ok guys here's one I just thought of spur of the moment. One thing I know about. EVERY diesel, not matter what make brand or model, HATES being run out of fuel, and will make you pay dearly (some in elbow grease, some in cold, hard cash) for the folly of running out of fuel.
NOW, here is my line of thinking. IF you had water in your fuel, it would settle to the bottom of your fuel tank. If you were draining the contaminated fuel/water from your HCFM, I'm ASSUMEING it would be better to do it with a close to empty tank rather than a full one, as you'd be draining all the crud out of the bottom of the tank. I would think, however, the downside of that would be you'd drain your fuel to a dangerously low lever, and what little you had left in the tank would, in fact be pretty rotten.
Is is better to drain the tank FULL, or empty? If it was FULL, you wouldn't run the risk of running your truck dry, I'd think. If you drained it EMPTY, you'd get more crud out of your fuel tank. Any thoughts on this, guys?

As stated in the prior post there is all kinds of info on this in the tech folder. You do want your tank to be at the lower levels and by inspecting what you drain from filter you should know if futher steps should be taken. Hopefully you will be using a high volume outlet and not get all that debri in your tank. So far I haven't had much in mineand hardly no water, now have 29k on my 04.

I changed my fuel filter about a week ago( i got the instructions on "how to" from the tech folder) and it said that it was better to change the filter when the tank was low. My fuel level was between a 1/4 and empty.
If you look under the driver side door, against the frame, you will see the HCFM.
It is pretty close to level with the fuel tank. When I changed mine about 4 to 5 cups of diesel came out (from the removing the plug). The filter was filthy but the fuel was very clean.
I went about 18000 miles before I changed the Fuel filters (should have done it sooner) but is was very easy. The only problem was getting the cap off the filter housing (the HCFM filter). The drive shaft is about 2" away from the filter housing and there is not much room to work.
From what I experienced I think you will be safe changing your fuel filters when you have a low fuel tank level. You do not lose that much diesel and in the tech folder it suggested to turn the key on but not start the motor. It said to do this 3 times. I am not sure why 3 is the magic # but I did it and had no problems starting on the 4th time.
It said that turning the key and not starting it gets the fuel moving through the system.

What do you guys think about that one? Thanks for letting me pick your brains.

As far as the level, I don't let mine drop below 1/2 tank for day-to-day use (never know when the pager is going to go off and land me at a structure fire for an untold number of hours). When I'm on the road, 1/4 is it.

part # as it relates to the HCFM
Seeing how we're talking about draining the HCFM, I saw somewhere on here, that you can get a kurled **** to replace the hex head, makes draining the HCFM much quicker, easier and cleaner. What is that part number?? I looked in on the tech folder, but it doesn't list it, and I can't seem to find any posts by using the search feature. Thanks for the help

Ok one more noob question, and I'll leave everybody alone, I promise.
IF I were to run this beast out of fuel (no I promise you I haven't done it, REALLY I haven't
) do I have to reprime the injectors by hand, or is there a manual pump on the block, or will the fuel system recharge automatically by itself?
If you all want to throw stuff at me by now, it's ok.......I have my helmet and flak jacket left over from when I was in the Marines
