Thanks. I contacted Schulz, and it looks like it may be a MSV10SA. I discovered that the tank had a pinhole in the bottom, so I just transferred the pump to an older 60 gallon CH tank.
Does anyone have any information on this compressor? It says Air Source/Snap-On model S340V. Tank manufactured in 1991. I contacted Snap-On and they said it was manufactured by Dee-Blast and discontinued in 1998, but that was the only information they had on it. I'm mostly looking for pump info...
