I've got a leak somewhere around the stock fuel filter. I think it's between the fuel heater and block. Is there a gasket in there? Do the heaters crack? I changed the filter and it's still leaking, so that's not the problem. It's a real slow leak, about 1 drop every 3 - 4 seconds, but enough to stain my driveway, which sucks since I run 10% WMO so the spot is black.

In a related question, anybody got a sure fire recipe for getting oil stains out of concrete? Simple Green, Bleach, Laundry Detergent all fail to clean it completely.

 

im pretty sure theres an o ring between there. but dont hold me to it

 

yes, there is a seal/o-ring between the heater and the head. i hope i haven't misplaced mine. as for the concrete, if you have some battery acid handy, it sure cleans it up. i charged the battery in my car not long ago and some of the acid bubbled out. the concrete right below is very clean lol

 

Hmm.. I do have some acid left from the new battery I got for my quad...
