Well, finally got the truck running back normal again and was going to take it out in the countryside to some property I have with a friend about 75 miles away from everything. Got the truck loaded up and ready to go and as the fuel pressure was just a few pounds low recently thought I would adjust it up a bit and did so in the driveway before leaving. It always runs a good 16-17 psi at idle, and down to a low of 12-13 at WOT. Steady running at 14-15 psi which is fine with me. Got on the road and headed out in the boonies early this morning. About 15 miles out noticed that the fuel pressure was down again, sometimes even hitting 10 or less, which then triggered the alarm on the Edge. Stopped on the side of the road and adjusted the fuel pressure on the Raptor back up to 18-20. Drove another 3-4 miles and it started doing it again. Now I am not one to do silly things like pee on electric fences and the like, so when something like this happens three times in a row, its time to take a hard look at whats going on and make a decision. Yep, I headed back into town because where I was is in the middle of absolute no-where and tow trucks are a long ways away. Good choice as within 5 miles the fuel pressure was not only below 10, it was down to 3-4 psi at times. Another couple of miles and it was at ZERO... was on the hiway by then going 50 in the slow lane with my flashers on. Made it to the turn-off and truck was then bucking from time to time. Idle speed and sound was fine but sure was down on power. You could tell that the engine was not happy. Last turn onto the main road to my house and I was down to 2-3 cylinders and not sure I would make it, but Mr. Cummins builds a strong engine and we chugged to the house like this. Smelled some difficult smells coming from the engine compartment and guessing that the VP was not happy with no cooling fuel and has signaled that its time that I learn how to change a VP. Anyone ever had anything like this happen? The Raptor 100 is less than two years old and until this time been very reliable. I have a call into PF/Raptor support but no return call yet... Any suggestions on which VP to get and sources? I am looking for a good price but would rather have one with a new or upgraded circuit board on the pump if possible. Thx, Joe --- Update to the previous post... Well, its been a difficult and wasted morning for the most part. Called Pure Flow to get raptor support and they told me that I had to call their Indiana facility. Called there and was shuttled to someone's number and it went direct to voice mail. Left my number and 2.5 hours Kyle finally calls me back. What a JERK! I had bought this Raptor 100 in October of 2009 from Vulcan Performance. First pump I received was dead out of the box so I called Vulcan and they shuttled me to PF who was at that time still producing product in Missouri. They took a week to get me a new replacement pump as they did not any gears left to make new pumps... Finally when they got a new one made they shipped it overnight on their nickle and its been running fine since that time. Evidently now production has shifted to Indiana and if you have a newer model product you have to go there. Older stuff are still supported by the Missouri office... thank God. Well, Kyle could care less about customer service but sure wanted to know the pump number and if I had sent the warranty card in, which I had done. Well he could not find the warranty info in his computer then told me "you must have bought this before Nov/Dec of 2009" so while I have 98% of all listings from this time frame, if you are not in my computer you get NO warranty!" I guess customers from anytime before fall of 2009 are worthless to him, or he sure treats them like this! Hmm, thats a good way to ____ a customer off! Now we are responsible for the Post Office getting the warranty cards to them as well I guess! That 2% of the PF customers that he mentions is not in his computer just gets to pound sand from the way he acts. I called the Pure Flow office in Missouri back and talked with Diane, who found my info in her computer right away. No questions asked, she was wonderful to work with and I have either a 6 year or unlimited warranty, depending on something. I could care less what it is, I bought the pump about 2.5 years ago so its well within both time periods and covered. She has a replacement pump coming out to me this afternoon and will change it next week once it arrives. Now for the next bit of good news. The system threw a Po216 code on the way home, but considering that the Edge was showing ZERO fuel pressure thats not surprising. Anyone feel that after I put a new raptor in the system that the VP is going to be worth a damm or reliable enough to trust on the road?

my raptor fuel pump stopped putting pressure out about 3weeks ago. the motor runs fine but no fuel pressure is read from mechanical and electrical gauge. checked voltage and it is good at 8.5 volts without starting it. the motor turns and there is no suction on inlet. so i told airdog about it and they shipped me a new one. i just installed it, and there is no suction. it will not prime. 2 spinning pumps, so what the heck am i doing wrong?
