R.Emm- thanks for the reply!!
I was thinking it might only be 1/2" ID, as it is extremely hard to fit over the 5/8" hose barb on the water heater. If it were 3/4", it should go on easily, I would think.. However, the actual hose barb on the Force 10 heater inlet is quite a bit larger than the real diameter of the fitting.
If someone with a 2GM
, 2GmF, or 2GM20
could confirm the size, I would appreciate it, as the 3GM
may have a larger pump, and hose, based on the larger size, need for more cooling
