2 months ago had the fuel pump fail on the M1165. I replaced it with the proper fuel pump, changed fuel filter. There was 1/8-1/4in of sediment in the bottom of the fuel water separator, but the screen was near perfect. When I changed the fuel pump it looked beat up from the push rod and I could depress it easily with my thumb. I fixed this and worked it perfectly.
I drive this truck almost daily and she has more power and no signs of problems, until this morning. It sputtered and surged (no crazy noises) then right as I found a safe place to park, she died. It was low on fuel so I assumed this was the issue. Added some diesel. I bleed the air out of the filter and she started right up, then made terrible noise, loud clanking that's worse with revving the motor. I killed it immediately. My wife gave me a look like $#%@~! Plan B trucks. I'll be taking the fuel pump off this weekend.
I'm a mechanical YouTube idiot, not a mechanic. I'm posting this with anticipation of failure, while its fresh on my mind. Please fill me in on anything I'm overlooking.
