I have a Vita Spa, MODEL: ELAN. It's 1995-1996 and I'm looking for a air injector for this tub to get it working. I have looked on Vita Spa website, but they don't have the part I need. It's the smaller jet in the tub, so if anybody can help me out that would be sweet. Cause winter is coming and need to get it working thanks for any help anyone can give me. Thanks Jeff
