ISX15 CM2250 fuel pump timeframe?

I'm curious as well, seems different dealers tell you different things and parts availability for them is a crap shoot.

A local guy told me he tried getting barrels and plungers for a 2350 but they told him the only way to get them is to buy the head and it all comes together in a kit. I think he said $1500 or $1800. Is that true? I have no idea, it's just what I was told.
