Racor- you the man!
<< 6) You state that a 10-mic pre-filter may be beneficial. I am using a Stanadyne 2-mic pre-filter that is clogging as soon as 2300 miles. It has a water bowl but has never had any water with the exception of a BB size droplet. The fuel in the bowl is very clean. There is a 5 and 10-mic element available for this head and bowl and I speculate it would probably go 10-12k miles which is my intended oem change interval with a 10-mic. Is this what you are suggesting as a possible benefit?
It sounds like you are plugging a little too soon, even for 2 micron. Find another diesel fuel station! A 10 micron will add some system life and let the OEM filter do some work. I'd rather you put a Racor on there of course. Our new 10 micron Aquabloc II is great stuff; very long life and 98% at 10 micron. >>
I don't understand why the bowl is so clean. I think the problem may have something to do with the media being so small. If you look in my pictures you can see that it is probably less than half the surface area of the oem.
Thank you for the reply.
PS- what series is the Aquabloc II filter in?

OK, here's my take on a couple key issues:
Gunk
The "gunk" in the injectors is NOT fuel related. I've tried to emphasize this, as has Dmax-man. It appears when the lines are removed and the crap from between the line and nut is dislodged.
OEM hose:
It is soft and spongy, and OBVIOUSLY not rated for a whole lot of vacuum.
Cold weather fuel:
In cold climates, we run winterized #2 diesel. To winterize, vendors will cut with #1 diesel, and/or run additives. Either way, do NOT fill your truck up with #1. A 70/30 blend with a good additive will suffice in most any climate. If you are paranoid, and seeing double digits below 0

I must say that this thread is most informative. Many thanks to Kennedy, Trace, George, and Racor for your insite and expecially taking the time for posting!

I copied and pasted what "Racor" said in here into a e-mail and sent it to the Engineer at Stanadyne that I have been dealing with. He totally agrees with everything "Racor" says.
