Clogged fuel filter
#21
My 8V92 uses a Luber-finer LFP816FN (secondary) filter mounted on the engine and a LFP815FN (Primary) mounted on the firewall. The secondary will clog up much faster as it is a finer filter.

One more thing.
I would like to remove the what used to be clear bowls on the water separators so as to clean them as they are black. They are plastic with tabs around the outside as if for a spanner wrench. I tried a strap wrench and it would not budge. Is there a special tool for this?

Racor has a special plastic wrench that fits the fins on their clear filter bowls. One wrench fits all sizes of their filters. I use one to change R12T filters used on many Foretravel Aqua Hot heaters.

Nope, that's good. I didn't know if you had the Racor filter or something else.

You might try heating the threaded piece with a hair dryer to help loosen it up. Sometimes heat or a couple of heat cycles can break threaded connection loose.

I know that it takes a LOT of force to break mine loose. Heavy duty strap wrench and careful attention to where your hands will land when it gives are the order of the day.

On mine, the wrench will not work because the filter assembly is mounted hard up against the bulkhead. Only a strap wrench will work (demonstrated recently at Speedco, they were impressed when I had to take it loose for them).
