Works but has problems. The problem is related to the spacing or location of the 1/8" NPT port for the pressure gauge. The pressure gauge is in contact with the mounting ring of the receiving cup. Luckily I had an extension tube to extend the gauge to clear the ring. The second problem arose about a year later when the plastic visor on the oiler broke on the threads and began to leak. I have two of these controllers and he did it on both. JB welded the hole, now it works fine. I had to deduct a star though.
