Barrel / Plungers are sold as a matched set. Must be replaced together. The only ones I could find were from a seller on ebay who claimed they bought them and didn't use them....didn't want to go that route. I tried multiple different avenues and could not locate them. There were a few spread throughout the country and apparently couple in India. The few dealers that did have them would not get off of them. The way to purchase them now is with the whole head assembly.

- If you happen to find them elsewhere, please let me know as I couldn't locate them individually.

- Yes, apparently the steel ones do fail as well. Not sure what happens first, the plunger or the roller....maybe one goes because of the other...not too sure. I was just informed by a very well known/respected engine builder (from this site) that they do not replace the head (which is how you have to get the barrel/plunger assemblies now) unless there is a fueling issue.


.....actually, jimeneztrans84, I think I was using the part number you provided on a post awhile back about the fuel pump situation.
