[C320-list] Which Racor Filter?

[Graeme Clark]

Jeff

I like your logic. I’d not thought if it that way before although I had noticed that the Racor is hugely over specified (in terms of flow rate)
I shall also fit shut off valves either side
I have had an engine stoppage in a moderate sea due to sludge in the tank getting stirred up (not my own  boat I might add) and anything that speeds a filter change is a good idea!

Maybe I’ll fit a second filter in a bypass loop too

I think there would be virtually no chance that the Racor would clog and not also have clogged the small engine mounted one having a finer filter.

I'll be fairly sure that anything that passes the Racor will also pass the engine mounted one and not be too large for the injectors to handle.

I think the Perkins OEM fuel filters are 2 micron, but I'm checking that.  I actually ordered some of them but haven't installed one yet. It only makes sense to me to have a fine "finish" filter on the engine and a more coarse filter in the Racor (not a 2 micron).

On the Catalina Direct site today, I came across their listing for a Raycor R15T, which filters to 10 microns. Catalina Direct's description for the R15T includes this language:

For example, there is what appears to be the same filter that only filters down to 30 microns. It leaves particles in the fuel that are too big and may clog the engine's filter. Another version filters to only 2 microns. This is filtering particles from the fuel that are so small it may clog almost immediately, leaving you without power soon after replacement.”
