Just picked up a 420 project that has the remote control valve attached to the TOM. Looking in the parts book, it should be a two way w/ break away. This one is only one and just has a hose going to the rear. Looking in the 40 operators manual, it shows the same valve, but my 40 TOM is different than the 420, it wouldn't connect the same. Anyway, I am looking for any info I can find on this valve. Trying to decide if I should keep it or not.
