Message: [QUOTE="DEEZUZ, post: 418142, member: 1508"] Had a 6.4 come in, low contribution on a cylinder or two. Did the ole fuel sample from feed tube. Sure enough, brass particles which I was told is the HPFP coming apart. I replaced and cleaned EVERYTHING [U]NEW[/U] HPFP HFCM Both rails 8 feed tubes 8 Injectors Fuel supply lines Fuel return line Fuel Cooler I also blew out any lines left over and dropped and hand cleaned the tank. Cleaned secondary filter housing, removing standpipe. Filled the system up with CLEAN fresh fuel. Bled out the system through the fuel cooler. Finally got it running and took it for a ride. Instantly I had almost 0 throttle response. My SFT's were from -5 to +11. All injectors bad again. I took a sample at the fuel cooler and sure enough, SAME brass/copper particles... Any idea on WHY the pump failed again or if maybe there is another source of the gold particles? [/QUOTE]
