Moeller Marine, Mechanical Fuel Tank Senders, Swing Arm, 7.5 Inch to 22 Inch Tank Depths

Another reviewer was bummed because he had to buy a conversion kit to send the fuel level signal to his fuel gauge. Actually, he just bought the wrong type of sender. This unit has a gauge right on it. When installed, there's a direct-read fuel gauge on the tank itself.And it's called a 'sender' or 'sending unit' because that's what it is. That's the name of the device that reads the fuel level.At any rate, the quality was better than expected. Much more robust than the unit it replaced. The float is some kind of rubber or plastic, so it won't absorb fuel like the cork floats and sink.And yes, it does come with the gasket and mounting screws. Nothing else is needed. If your fuel tank is clean and flat around the hole, and your tank screw holes are not stripped and still give a good 'bite' to the screws, no gasket sealer is needed.These come in different length, so measure your tank depth. If your tank is between available sender sizes, you have a bit of a decision. If you get a sender that's too short, it will be accurate when it reads 'full', but when it reads 'empty, there will still be fuel in the tank.If you get a sender that's too long, you can bend and straighten out the float arm a bit. Then when it reads 'empty' the tank will be empty. But, when the tank is full, the gauge will show that it is not-quite full.I chose 'too short' so I have a bit of reserve fuel when it shows 'empty'. In retrospect, that was dumb. I'd rather know exactly how much fuel is left.

Fit perfect

Perfect product. Easy to install, high quality stuff. I even found a conversion kit that allows you to connect this to a dashboard so it's a good starter gauge if you have limited funds. What I mean is, put this one in on the tank first. Then later, by the converter that connects it to a dashboard fuel gauge. I love it, glad I bought it. Put it on my built in tank for a 1981 gastron fiberglass run about 16ft boat.

The unit itself is great, strong and easy to install, BUT THE DESCRIPTIONS ONLINE AND ON THE PACKAGE ARE VERY MISLEADING. The ad calls it a Mechanical Fuel Tank SENDER. and states that it is "Calibrated to the industry standard of 33-240 Ohms" and "Compatible with option dash mounted gauge" There is nowhere in the ad or on the package that references what additional hardware is needed to connect it with the dash gauge. It took some research to figure this out. MINIMALLY, believe that the ad and the package should state that an adapter is needed to connect it to the dash gauge, and it must be purchased separately, and give the part number to order.Having said this, I would give the unit itself a 5, but because of the misleading or incomplete information, have lowered it to a 4. If additional hardware is required to take advantage of the fact it is a SENDER, that should be clearly and plainly shown.

Great alternative to a new electrical gauge

The item was find but wouldn’t fit through the stand pipe of the tank.

Satisfied with the gauge so far. Only had it for one trip in the boat. Seems simple and dependable. I use it in a 75 gallon ranger bay boat tank. I’ll probably add the electric sending module.

I used this sender as a replacement in my boat’s below deck tank after both the electronic sender and remote fuel gauge had failed and left me without fuel twice. This sender is robust and seems to be of good quality. Some important install notes:-The standard ANSI/SAE 5-bolt hole pattern is slightly asymmetric and only allows for one-way install. So if you plan to reuse existing holes, it can only mount in one orientation.-Neither the gauge or the float swing direction can be adjusted (like on some electronic ones) The gauge itself only fits in the sender housing one way.-Comparing the gauge dial to a clock (1/2 tank at 12 o’clock position) the nub in the housing is at 6 o’clock. The float arm swings in the 3 o’clock direction.Luckily this ended up working well for my tank shape/orientation but it may not for others without some modification.
