Has anyone here used the Garmin GFS-10 fuel flow sensor with Mercruiser 7.4 MPI engines? I have a Sea Ray 340da with 7.4 MPIs that I would like to add the fuel flow function to my Garmin 4212. The GFS-10 is made with 3/8" barb fittings and is rated at up to 50 gph. My mechanic says the fuel lines are 1/2". Not quite sure what to do. Any suggestions?
How did you make out with the GFS-10 installation. I just installed a Garmin 4208. I would like to install these on my 1996 twin Marine Power 454's, but I believe I have return fuel lines (I don't know for sure)?
I didn't . . . I went with Floscan instead and they have worked flawlessly. There were some problems with the mounting of the Garmin flow sensors due to the routing of the fuel lines. I did head from some people who had used them and they worked fine.
