Racor 1000 Fuel Water Separator

[TAbbott]

I've got a Hatteras 53' convertible with twin DD 8v-92's . Both port and starboard have 3 Racor 1000 fuel/water separators in line to each engine. I'm trying to find out what the best micron filter cartridge to use.

Use the search function. All kinds of opinions over quite some time available to you.

Detroit's opinion was 30mic for the 8v82TTI, so that's what I used.

I use 30 as well.

30 for sure as long as you have secondary filters between the engine and the racors.

I use a 10 on the secondary.

if you have three separate filter units you could taper your filters from 30 down to 2, although DD doesn't recommend. I have dual racors and use 30 in each, but mine are plumbed where I can filter through either or both, typically alternate for optimal filter usage.

The only advantage of running both Racors is you can plug’m up together. You have two so you have a fallback.

I use the 30. Part # is PMOR 2020. Defenders has them on sale right now for $11.99. I just ordered a few.

Detroit 71 series manual says 30 micron for the primary filter unless you are in "severe" duty which case you should use 10. I think they describe severe duty as mining operations etc which would be dirty. Regardless I am going to try 10's for a while. I would avoid the 2-3's i think they are too restrictive and may cause problems.
