Changed fuel filter for the first time at 10k , probably go to 15k next time, filter looked new, used Dave Fritz method , not nearly as easy as my 92 12v with the prime loc, the old 12v was laughing at me while I was standing on a box trying to wipe out the cannister, who ever designed this new setup never had a filter problem in the dark. Will standby an wait for someone to develop a system with a self contained filter like the old 12v. But the most important thing was it fired right up no problems. Its fun to do something right once in a while
