Hello All: Does anyone know of a source for a salvaged or rebuilt air injection pump for my M119 motor, part #1191401785?

New ones are going for $1000 to $1200, but its really a useless part except, now that its failed, it lights up my "check engine" indicator. I'm willing to swap in a salvaged or rebuilt part just to get rid of that annoyance

Thanks in advance,
