AIR pump delete pulley too small
Just installed the delete pulley (305 TPI) and the stock belt doesn't fit. The new pulley is noticeably smaller than that on the pump. Can I just run the disconnected pump with the air hole blocked off (or not blocked off), or would it be better to get a smaller belt? I don't think I have enough room to take up the slack with the tensioner and I thought the pulley worked with the stock belt. Thanks
