I swapped to 444c compressors after thinking one of these had blown, but turned out to be a relay.

These have been used well, so the price is adjusted accordingly. I’ve had to replace the top head of one of them, as it had split from tightening a connection.

I can take videos of the pumps turning on from a 12v battery, or show in person.

Comes as is- missing 1 front air intake & had to make 1 mounting bracket.
