One of the only things I didn't like about the fuel cell was that the cap was almost impossible to get off without a screwdriver. I found a replacement from Summit Racing that is much better. Instead of a sheet metal ring on top it is a thick aluminum ring and it is sealed with an oring. I got some stainless bolts to mount it and it makes a huge difference. I highly recommend this to anyone that needs a new cap for their fuel cell.
