Message: [QUOTE="HeavyAssault, post: 1540036, member: 782"] Yea. I found the newer S&S video that gave some internal understanding to the "how it works" of the HPFP. I gathered the biggest point was not that the roller bearing of itself causes the problem, but a two fold event that requires the guide to turn 90* to the cam which causes the roller bearing to now be in a "not as designed" orientation. That is when the most severe HPFP failure issue can occur and happen where the bearing is eaten up by the cam. I want to say the video gives credence to the air that becomes entrapped in fuel as the possible/principle source of creating the environment to cause the guide to rotate 90*. I'm not trying to say one way or the other how these failures happen. Just giving info that I gathered from the video. So with the combined factors of air entrapment and poor fuel lubricity these are key elements of the HPFP failures plaguing the industry. Yes, one can cause the issue just as much as the other, but both issues combined cause a huge issue to rise up much faster. Does that sound about right? I would never disagree adding filters, additional water removal, supporting pumps, and air removal are quite effective "insurance" to helping our fuel systems. [/QUOTE]
