Cutting 160 pump for 13mm p&b's

On a serious note, the average person wouldn't believe that the tiniest scuffing on a plunger often means it gets thrown out. Barely can see discoloration from the polish. I'm sure Seth has a couple pics laying around. The ol fingernail trick doesn't apply to fuel injection.

These were in a truck for the past few years. They are Rockentek 13's. stuck a plunger because he found the limit of the fuel supply system and ran it dry on a long highway run.
