Anyone know if the the cool shirts made by "cool shirt" and ""F.A.S.T. fresh air systems technologies" have compatible fittings? the reason I ask is our lemons car has a "cool shirt" cooler and plumbing in it and I can get a good deal on a "F.A.S.T." shirt. Best I can tell from the photo's the fittings look the same but any off the vendors I've called aren't sure it the plumbing is compatible. thanks in advance if you know the answer.
