fuel gauge
 

when I have power turned on fuel gauge goes back and fourth.it is never steady. what should I ck for first? bad connection or corrosion at fuel sending unit?thanks

Same thing happened to mine. I chenged out the sending unit and it stopped doing that. Of course, you can always check the connections first. Be sure there is no corrosion on any terminal.

From my experiance its been intermittant voltage/bad conn at the sending unit assuming its doing this on dry land. Mine did this at first on dry land and then when I was pitching side-to-side in choppy seas. I went ahead and bit the bullet and went digital.....Got tired of wondering where exactly I was between 1/2 and 1/8 of a tank....One of the better things I ended up doin to my Welly

SSI when you say digital are talking flow sensor or what?

correct. Its pretty accurate too. Farthest off its been was 4gals....
