CUCV Bumm'n Me Out Pt 3

Hi All

Still fighting the M1009, and she's still winning....DOH! I was reading
a post from the "Diesel Place" that Mike Maynard had sent me (thanks),
and it went on and on about air in the system, which I think is my
problem. I forgot to mention something unusual (to me anyway) that
happened Saturday when I swapped injection pump top covers.

When I took the cover off the pump, there was diesel in the bowl
underneath the cover. I went and got the cover off my other engines
pump, and when I came back to the truck the bowl was empty! Where in the
world did the diesel go? I saw no wet spot, and I had the return line
that connects to the top cover turned toward the side, away from the
bowl, so it couldn't have siphoned out. So what's going on here?
 
It was a month ago, so I'm not 100% sure, but when I took the HUMMV
cover off of the pump to replace it with the CUCV one, I'm pretty sure
it still had diesel in the bowl, after being shipped cross country.
Before I waste my time trying to re-bleed this thing again,I just wanted
to know if this is important, and what am I missing?

I have no visible signs of diesel leakage anywhere, I realize this
doesn't guarantee that I'm not sucking air somewhere. I may, as Stu
suggested, install an electric fuel pump back near the fuel tank to
start pumping as soon as you activate the ignition, and thus pressurize
the system before you even crank her, but to me that's a band aid, since
the truck was originally designed without a auxiliary pump, but if it
fixes my problem, at his point I'd be happy. Besides, the electric pumps
extra pressure might push diesel through, where ever the air is getting
sucked in, then I'd find and cure my air leak.....that is if I have a
air leak.
