I've been battling this issue for the past 3 weeks on my truck, its always a major pain every time I do the return caps on this thing. But the caps for #2 & #8 won't seal up for more than a day no matter what I do. I am using number 111 Viton "o" rings, and have tried two different brands of caps both had no burs or damage. I have tried using engine oil when installing the "o" rings and the caps, as well as my old method of white lithium grease. I tried replacing the individual caps that are leaking as well as the entire bank of caps, and have cut the hoses so there is not bending between them. After one day of driving the caps start leaking. Here is my return line routing that worked best in the past, I have the fuel filter return removed. The IP return does not enter the cap system since I believe it was causing more leaks with the added volume of fluid to move. I believe the issue is vibrations from the line between cylinders 1&2 that causes #2 too start leaking, and I would like to remove this cross over but I can't find a 1-way dead end late style cap. Would the 1-way early style barb cap work with the newer size hose? The leak for #8 I believe is caused by the short line between its cap and the factor 3 way block bolted to the intake. I can't figure out a better way than it already is, I have the block rotated so it shouldn't be putting pressure on the cap.
Anyone have a better routing method?
