adding an inline fuel filter.

[AKJohne]

Don't get the need for the Racor on the transom if you have a second separator on the motor.

I’ve a simple inline metal filter in front of the flow sensor and 10 micron Racor separator behind.

It may seem a bit redundant, but clean fuel is critical... at least IMHO.... the Racor has a metal bowl with a drain, occasionally I will check for water in the fuel before I start the motor. or if having issues I can check, something you cant easily do with the one on the engine. Also the threads on the Racor and the engine mounted Merc filter are the same, I carry extras of each and could substitute one in either location in a pinch. I have never had water in the fuel.... yet....some people struggle with water in the fuel and blame in on condensation, which in my opinion is unlikely.
I also run the kicker off the same set of filters, The Merc filter housing, like the Racor has two outlet ports, I have a ball valve on the line to the kicker so I could isolate if need be. However typically I leave that valve in the open position and it works fine. The fuel flow sensor is connected to a NMEA network and displays fuel info on the plotter. Essentially that is my "virtual fuel gauge" . I have a float gauge mounted on the tank under the floor with a access hatch to view if need be. The virtual gauge is more accurate as the tank is 9' foot long and 22" wide, the float works, but it is not the same as knowing how many gallons are left in the tank, something the network does with aplomb.

Running 2 strokes, I'm a diehard filter guy, but you gain nothing stacking filters in a system.

Fuel flow systems are great for optimizing fuel consumption but... IMHO pretty useless when it comes to monitoring fuel supply levels. Forget to enter the amount of fuel you put in once and your done.

I have two tanks with a 147 gallon capacity Rarely fill both tanks unless I'm fishing a tournament or heading offshore for the day. Usually just put in $100 or so before heading out each morning.

Both tanks have digital (reed type) fuel level sensors that are unaffected by tank size. Readings are feed to analog fuel gauges at the helm and digital gauges on the chart plotter.... close enough

You need to read the above posts on WHY people are adding an extra filter. And it's not to 'get more filtration'...

As above, read the posts in the thread before firing off half-cocked...

:facepalm: so not true! If you forget and can't remember, just top the tank up and set the fuel volume to whatever is in the tank, and you're good to go...

and in this case, just keep adding whatever you put in, and you know you have more in the tank than is indicated...

Yes, we all have those too.

Seems like this thread took a turn sideways, thought it was about installing a fuel flow sensor and what works... personally i would never install a inline metal filter, sure they work and they are cheap, which might be the best reason for some. The issue is if they get crap in them you cant drain or remove easily. With a racor type you can verify fuel quality pretty quickly. What makes a racor a "stacked " filter and a inline not?
inputting fuel data... tough job with a simpe fix, dont forget..
Do you check your oil before you leave the dock? Or after the motor starts knocking....

i would prefer the accuracy of a sensor over a float anyday . geeezalready
