your talking about making a kit out of all rubber plugs and a china made qauge arnt you? Ok first off not to be a dick but i also tried using those and they didnt work for shit (for me), they kept blowing out. Go down and buy a solid piece of aluminum, bring it to a machine shop to have it spun to size, drilled, and tapped and let me know how much that will run you buddy. Now add $19 for a GOOD 0-15psi quage and air valve, then grab some rubber and some stainless bolts. In my opinion $55 is a damn good deal for a kit that will last you forever unlike those crappy kits you use. Im MAYBE making $15 at the most, Now add in the time it takes me to make them....and its not a fair price? i think its damn fair. Use what you want to but dont talk shit about the things i use....so far 8 people on here think its a pretty fair price. :laugh: thanks guys
