thanks andy and john
i was thinkin of pulling it and capping it off
the trucks came this way when the guy bought them 2nd hand
these guys arent rough but they def aint easy on em
they do heavy awkward stuff and its very busy (metalizing) so im not sure if removing it from the circuit would be best in the long run for this application

it is a long cylinder up the backside of the right mast rail
it has what looks like a schrader valve with a small cap and a metal bracket protecting it on top

John i thought you were in texas

thanks again guys
