    Flow Rate eh700 ?-gctid379535

    Hello,

    I am thinking about installing a pre-filter-separator for my EH700 engines.

    Choosing between models of filters Racor : 500MA, 460R or 245R.

    What do you advise ?

    What is the required flow rate for engines EH700 175hp ?

    Thanks for help...

    I replaced mine last year with the 500's. I think most of the guys with the 175's have either put on the 500 or 900's.

      OK, then it's smart to have flow rate 60 gph ?

        Your max fuel burn rate per engine is about 9.5 gph.

        Your max flow rate per engine is about 20 gph.

        Using the smaller diesel filters results in a much smaller filter surface area and a much higher frequency of replacement and problems.

        Additionally most of the smaller filter elements cost a good deal more then the racor 500 or 900's so cost down the llne iws greatly increased.

        As a result many folks go with the Racor 500 or 900 as stated as a good compromise upstream of the on engine filter.

        Perhaps compare filter element prices and filtering areas to get a feel for this situation.

        Persons who cruise extensively and/or expereince poor fuel often then put a 3rd filter in front of the Racors of a bulk spin on type to take out the heavy sludge.

        Perhaps a good time to consider vacuumn gages as well so you know when the filters need changing.

        Hope this helps

          I use the Racor 900's with 2 micron filters. Also have the T-handle vacuum gauges. Don't have any problems with fuel flow rate.

            I have the 500's also. I left the originals as backups with simple manifold system to allow quick change if in rough seas when needed.

            Good Luck
