I've had great luck with the Quicksilver or OMC fuel filters. They're cheap and they work. I am familiar with the see through Racor's and the only one I've seen in service leaked, he replaced it with a Quicksilver. Good thing it was an outboard and the filter was mounted in the motor well. I believe most of the junk we get in our boat tanks comes from the lack of care at supermarket type gas stations. Although you can't see into a Quicksilver or OMC spin on canister fuel filter, I always pour the contents into a glass container to see if I've got a lot of water or contaminants in the tank.
