When you have the chance, affix a yardstick to the side of the tank alongside the sight tube. Divide the gallon capacity of the tank by the number of inches high the tank is and you will know how many gallons each inch represents. Cheapest tank level indicator you will ever find and it's pretty darn accurate.

Upon your recommendation I found that I was turning the upper valves to the off position when trying to get a reading. They are a lever type ball valve and when the handle was lined up with the line I assumed it was open not the case . Other than feeling like a dummy I feel much more confident about my fuel monitoring system now. thanks

Sight tubes all the way. My fuel gauges don't work right now. All three are wrong. In my experience the senders seem to fail frequently. The floscan is great - but mine doesn't read the fuel used by my generators. I used them a lot in Alaska. As mentioned before, sight tubes don't lie.

Either get a hour meter for the noisemakers and do an estimate, baased on run time ,

Or get a cheap copy of a Flow Scan to keep track.

Careful, that only works if the tank is even shaped and not tapered to match the slope of the hull or some other odd shape.

Have an 8 position Tank Tender system to measure the 2 fuel and 5 water tanks. The John Deere display has a real time GPH function utilizing data from the engine computer. Dealer swears they are very accurate and don't require calibration. We shall see. Extremely happy with my Tank Tender system.

When I installed my new plastic tanks, I left a slot in the supports on each tank so I can see the level directly. On initial fill I stopped every five gallons and marked the tanks. Now with a quick look I know exactly how much fuel I have. I also monitor engine hours. That said, since my four year average fuel burn is 0.35 gph, I don't worry too much about fuel.

The generators do have hour meters. I don't know their burn rate yet though.

A second vote for tank tender. I find it to be just about as accurate as dipping.

Sight tubes on both saddle tanks with crossover that I always leave open. An old salt told me long ago to use the sight tubes for fuel gauge only. This makes you go down into the engine room every day and while down there check all fluids, bilge condition and other system checks. Our engine rooms should not be a place we try to avoid!Simple and preventive all at the same time.

Good point. The bottoms of our tanks are slightly angled down and the gravity feeds are at the lowest point. The previous owner who had the tanks fabricated and installed calibrated them by adding ten gallons at a time and putting the number on the sides of the tanks next to fuel levels in the sight tubes.
