My sender failed on my 1998 272 Sailfish. Power 225 Yamaha 2 strokes with fuel management.
Does any one know the ohm reading at the gauge on this set up so I can order the right sender?
Thanks

Re: Fuel Gauge Ohm Reading

If American, they are all the same (marine senders). yes there are better quality senders and crappy senders but the OHM range is the same.

33 to 240. I think 33 on the full side, and 240 on the empty.

Thanks,
Grady confirmed the 240-33.
I didn't know that was full/empty readings.

All I did was go to the site for WEMA senders, measure the tank depth and follow their instructions. I have replaced both senders with the WEMA senders, about 3 years ago, and haven't had any problems. They have less parts to fail and no circuit board in the tube like the "old" sender.
Here's the page for the ones I ordered:
