Arima fuel tank gauge
« on: March 03, 2017, 11:27:24 AM »
Hi, bought a SR 19 two years ago and the ground lead for the in tank fuel gauge was disconnected by the previous owner. Someone told me maybe the previous owner disconnected it at the tank because it was dangerous. Anyone have thoughts or experience with that? I was going to connect it to see if it works with the Yamaha digital guage on the helm dash, but wanted to get thoughts from the group.

thx Brian

I recommend the unit, in the 16-17" length for a 48 gallon tank.  It is not as susceptible to splashing.

Mine is connected and the worse thing that has happened is the gage has told me that I have to pry my wallet open and buy more gas! If you find the sending unit has failed go with the recommendation from MS, the swing type do not work very well with our odd shaped tanks.

This is more to do with USCG CFR 183.572 (Transport Canada (2010)- TP 1332 E) ,  this regulation discusses the potential for a spark between a fuel nozzle and metal fuel fill or other metal fuel system components when fuel is flowing generating a static electric charge. If all the metal is grounded together the potential difference between components  will be low and not cause a spark.

  CFR 183.572 - Grounding.

Each metallic component of the fuel fill system and fuel tank which is in contact with fuel must be statically grounded so that the resistance between the ground and each metallic component of the fuel fill system and fuel tank is less than 100 ohms.

Transport Canada (2010)- TP 1332 E construction standards sub-section 7.9 grounding of fuel systems.
 7.9 Grounding

7.9.1 Each metal or metallic plated component of the fuel fill system and fuel tank that is in contact with the fuel must be grounded so that its resistance to the vessel ground is less than 1 ohm.

7.9.2 Ground wire ends shall not be clamped between the fill pipe and hose.

7.9.3 Static conductive neoprene tubing or piping that is used in lieu of metallic conductors shall be:

    clearly marked as static conductive; and
    installed in direct contact with non-painted attachment surfaces.


IMHO
I would not have disconnect this unless there was a issue with the sender.. pull the sender and test it out of the tank before hooking up...

Thanks DevMah, its the standard factory arima clear plastic transom tank, two wires are connected to the sender, which is exposed at the top of the tank. Green wire from the center bolt goes directly to the Yamaha gauge at the helm, and its connected still. Black wire that went to battery (-) is disconnected from the sender. From what I understand you saying, it is actually more dangerous that the ground is disconnected, as now the sender itself which is metal is not grounded? I care little about the gauge information on the dash as I can easily see the fuel level at the tank.

Should I re-connect the ground back up for safety/precaution regardless whether it works?

Thx, Brian

Yes the previous owner should have disconnected the positive side and left the negative (B-) still attached to the terminal.

Here is a link to test the sender  http://www.pbase.com/mainecruising/fuel_sender_testing
