    fuel filter question-gctid378574

    I just installed new 2 micron filters on 4/14 and brought the boat from Everett to Port Angeles. Yesterday after halibut fishing the starboard engine shut off underway due to a clogged filter. Question is do I get new 2 micron filters and keep catching everything or do I go back to the 10 micron?

    Let me add that I am assuming the filter as opening the cross over valve allowed me to run back to port on both engines.

      Interesting.

      Perhaps the fact that these clogged up on you so quickly, says that your fuel is somewhat contaminated!

      I'd buy a RACOR system, and install it onto your base unit.

      If you know the thread size of the base adapter, you can choose the correct RACOR cartridge.

      All metal bowls interchange.

      If gasoline, NO... not like a SBC oil filter base adapter.

      Oil filter base adapters use a by-pass valve for when the filter media becomes saturated beyond what engine demands are.

        These are twin diesel, and I do have the racor filters. I am now suspecting a fuel pickup issue as opening the cross over valve is pulling fuel straight from the port tank not from the port filter if I recall...

          A bit more info would be helpful. Not knowing what kind of boat you have or what kind of fuel switching setup you have, it's kinda hard to offer meaningful suggestions. It seems a bit odd that opening the crossover valve to draw fuel from the port tank would not go through the port filter. Bottom line, sounds like your starboard tank is contaminated.

            Sorry I was doing my posts from my phone and was finding it difficult to get the exact message out there.

            I have a '87 3870. I went back down to the boat yesterday and realized that my last post was incorrect. Opening the cross-over shutoff valve actually pulls fuel after the port filter. Thus both engines ran just fine off of the port tank/filter. I have now narrowed it down to exactly the starboard filter being the culprit, though why it clogged so quick I could only hazard a guess. I had a sealed (original packaging) Racor R26S on the boat and I picked up a new one as well. The one on the boat is on the starboard tank side, the new one is on the Port. It was likely a bad idea to use the filter that was on the boat given that I don't know how old it was, or how long it was on the boat, etc.

            For now, I will get another (and a couple of back-ups) 2 micron filter and replace the starboard side and see how things go.
