"On the shelf behind the seats which supports the battery cover, I carefully located a spot where I drilled a 1/2" hole through the sheet metal. The hole was drilled almost directly above the top fill plug on the shock and it gave me a nice viewing port so I could see the plug and unscrew it and then use a small hand pump with hose to fill the shock. I use a rubber plug to seal the hole. It's tight in there, but it worked for me".
