Anyone know who makes the motors for these pumps? Want a spare just in case.

If it has a sticker on it try lifting the stick, some company place a sticker over the original name and part number that is stamped on the outside. Goza used to be that way and I info a racer of that which led him to motor manufacturer.

Mine has an Autometer sticker on it.

I don’t think that came there from factory.
