Racor Gasoline Fuel Filters: Why Not for Diesel ?

I have installed 320RRACO1 fuel filters for my Yanmar diesels. When I purchased them I was told that I could use them with diesel fuel. I am now wondering if I have been given a bum steer. Any advice from the Brains' Trust would be appreciated.

Also as it does not have a fitting hole for a pressure gauge, can I add one in line before the filter. If so any suggestions as to what brand, preferrably with a fixed second indicator?

Parker - Racor web site seem to indicate it is designed for Gasoline.

You can sail anywhere on the planet and never be more than 7 miles from land - it might be straight down, but its never more than seven miles

Filters designed for use with diesel will always seperate the fuel from the water. Those designed for gasoline will usually but not always allow water to pass.
As the results of water in diesel injectors is relativly horrific I'd stray as far away from gas filters on a diesel as I could.

Speak to Thorensens RACOR 320RRAC01 RACOR 60 GPH Fuel Filter/Water Separator - OUTBOARD ONLY Ships Store Torresen Ask them if it is possible to buy filter elements suitable for diesel (quote your Yanmar model) for the 320R-RAC-01 unit . Which by the way is specifically designed for OUTBOARD GASOLINE engines.

I don't think the water seperator is in the filter it is part of the design of the filtration system.

Exactly so. It is the element material.

To my knowledge, expereince (and checking the Parker web site,, Raycor uses the same aqua-block media in both and they both swell and close off in the presence of water.

A metal bowl is required for gasoline inboard aplication. As far As I can tell, that is the only difference. There may be gasket material differences.

I have had phase separation with gasoline and had the filters stop within 500 yards both times. Thus, the admonition to carry a spare filter, wrenches, and something to drain the water into.

Check the bowl every time when the temperature drops in the fall.
