DS4 Teardown?

[Mainous]

Anyone ever tear one of these down? I have a spare. I had it tested and it is not putting fuel out of the #6 line. Given the fact that this is a rotary pump, it has to have some sort of blockage.
Looking for any advice or instructions on tearing one apart.

I have $50 in the pump so if I trash it I'll chalk it up as a training exercise!

This may help....It's a worthwhile read if nothing else. http://www.geocities.com/MotorCity/Show/3753/6_5_litre.htm

Thanks for the feedback. The link was helpful. I ended up tackling it without documentation and found the problem in about a half hour. There are check valves with a needle and seat in each discharge nozzle. Some one had flipped one of the needle and seats upside down. I'm going back to have this thing tested again but I believe that I now have another good spare pump.
