Fuel filter "leak"

[drjay9051]

Just changed the fuel filter on my Kioti CK 25. Gasket is good. When I start the tractor there is a slow drip at the bottom of the clear filter housing. I noticed this after tractor seemed to be sucking deisel. If I turn off tractor but do not turn off petcock to off drip continues but very slow.

As I mentioned the gasket is good and clear plastic housing is NOT cracked.

Im thinking I just need to tighten the filter a bit more. I tightened the metal threaded ring and have about 3 threads still showing on the bracket that holds the filter.

Im afraid to wrench too hard as I am heavy handed and have already stripped a couple of bolts around the farm.

Filter is hand tight. Should I use a slip joint pliers and tighten till all threads are covered by ring??


Edit: Just read another thread. Looks like the bowls are prone to cracking. Im assuming if its the bowl I would see the crack, no??

You would be able to see the crack after bowl removal. The clear curved plastic makes it hard to see a crack unless you can see it at just the right angle. In my case, it was a single vertical crack that I could not see or feel until the bowl was off of the machine. The bowl uses an o-ring seal that should not need to be that tight. Hand tight is plenty, no tools are needed.

Remove the bowl, inspect the bowl and O-ring, if it all looks good then clean the sealing surface and reinstall hand tight. This won't cost you anything but a little time.

No diesel should leak at all.
