my new to me 312 fastech im still learning as well. i know i went on a 70 mile poker run and ran her pretty hard with a full tank. came back showed still above half. was very shocked. went back out yesterday with it showing between 1/2 and 3/4 made it about a mile dropped to 1/4 yellow light came on, got to the island knowing i had a fuel dock nearby if needed. fuel gauge showing back up above 1/2. decided to play it safe and put $100 in for the ride home. fuel gauge now reading full again. not sure what to think at this point.

When the gauge on my 312 starts bumping off full (in the water), I have used 90 gallons of my 128 total. I run a GPS and typically get about 1-1/2 mpg if I'm not running hard. I didn't know about the adjustment screws on the sender. Definitely going to take a look at that. It's not uncommon for me to run 100 gallons on a weekend and I don't like it after the needle comes off full. Makes me nervous.

I recently replaced my sender with a wema model and my fuel gauge when I put the new motor in. I filled the tank, ran a poker run and ended the weekend on 1/2 tank according to gauge. When I topped it off it took 57 gallons...almost half the 106 gallons it holds. ( I think I'm pretty close )

will bring it just below 1/4. Once I learned that lesson the hard way, 1/2 became the new E. Having said that, I never have completely filled it, but if I put 60 gallons in when it says 1/2, it will be buried on Full for quite a while.

So on my 370SS I've been trying to decide if it's full when it says full or empty when it says empty. Having added 170 gallons when it was on 1/8th tank I can assume there was 50 gallons left in tank OR I was nearly empty and the gauge is wrong when it says Full. My choice is make a spill when it spits out the vent or run it til it quits, probably never going to know.

The gauge starts to move off F right away when I run it.
So today I filled it to the top where it was about to over flow.
106 gallons went in.
