Attention: TDR Forum Junkies 
I've had my Grovers in for awhile now, was amazed at how much air they are going through. I have dual aux. air tanks in the tool box, total capacity 22 gallons. I HAD the tanks piggybacked using a length of that yellow extendable hose. I decided to check it today, using some soapy water, could have taken a bubble bath in the tool box with all the leaks 
. Come to find out that the yellow hose had worn through were it's connected at the hose barbs on the line. I replaced that line with a piece of the hose that Rickson's supplied, using 1/4"NPT brass compression fittings, now all is well. Not a big deal as all I was losing was air, but be aware of the possible failure if you are running the horns with a compressor and have that yellow line somewhere in the install, it may cost you a dead battery if you don't have your compressor set up to only power up when 'keyed on'. There's a pic. of that yellow line here, if your interested...
