EDIT, I thought I had a AD-100 when in fact I have a Raptor pump unit. Believe its pretty much the same except without the filters. Have changed the thread title to reflect this. ~~~~Installed an Air Dog 100 on my truck last weekend and while its running, its not running right. Am not at all experienced with diesels (am a airplane mechanic) so wanted to post here to see if there is something that I have missed.The pump "seems" to be working fine. I say seems as three times now its "hiccup'ed" on me. Driving normally (not WOT) at about 40 mph or so the fuel pressure dropped from normal levels to 7-8 psi, activating the alarm on my Edge Attitude display. No difference in the way it drove, just lost almost all the fuel pressure. Ok, so I just increased the pressure a bit on the pump (was steady at 14 psi out of the box) to about 20. Well when I did this the damm truck would not start. Have now dropped it back to 16-17 or so and hope that it will start and not do this. I have checked the wiring and its all fine, so do not know what in the world is going on here but am concerned that the pump or motor is going South.A follow up. Adjusted the pressure down to about 17 yesterday trying to get the "hard to start" issue taken care of. Had heard that fuel pressures around 20 or so can make the truck hard to start.Just drove the truck to the store and back. Its getting worse and worse than it ever was. With the stock LP the pressure would stay at 10-12 psi most of the time. At WOT it would sometimes go to 7-8 psi, so I felt that it was time to be replaced to save the VP-44. As well it would ALWAYS start on the first hit of the starter, always.The new AirDog pump on the drive today started off fair, with its taking a bit of cranking to start. Pressure came right up to 16 psi. Drove to the market, about 2.5 miles. Along the way driving at a steady 40 mph the pressure started fluctuating, from 16 down to 7 psi, at an even throttle setting. Came out of the market and it took over 5 minutes of cranking to get the puppy started. Pressure was at 16 at first then dropped down to 10 or so during cranking. The stock LP never did this.Finally got it started and went to the post office. Inside 3 minutes and same thing but got it started faster by moving the throttle back and forth. Once it started the pressure started doing the same thing, going up and down from 16 to 7 psi, and this was at idle under no load. Before you ask, voltage was a steady 13.7. Nothing at all has been changed on the truck other than the AD-100 pump.Hope someone has some ideas on this!Thx,Joe
