[C320-list] Fuel sender puzzler...

[Dave Hupe]

There is a procedure posted I think in the association technical documents to test your fuel gage.  Try that?
Dave - I suggest always specify your hull number when you post anything so people can determine if their boat systems are similar to yours and their answers apply.

The fuel level sender is positioned in the deeper part of the tank forward. I have just returned from a ~14 hour motor and filled up just before leaving. The gauge still reads full after returning and I ran pretty hard (3000 rpm) so I assume consumption was at least 1/2 gal per hour or more.

The sender was just replaced 2 years ago. Any ideas on how to calibrate this? Do I need to replace sender? How do I compensate for a trapazoid shaped tank? Anyone with experience on this?? I appreciate all thoughts.
