Moeller electric fuel sending units receive fuel level information via the float.
This reed switch sending unit is suitable for gasoline, ethanol, diesel, bio-diesel, and non-potable water. Calibrated to 33-240 Ohms, it is made of durable 316 stainless steel. A rubber gasket is included for proper mounting. This is a Direct OEM sender replacement by WEMA USA.

If i have a "4"-5" neck on top of the fuel tank which the sending unit can mount to, can i calibrate the gauge to disregard the neck length and only measure the tank?
Unfortunately these can not really be calibrated. You would have to adjust the value of the resistance in the sender or adjust it, and it just seems like a little more work than it may be worth.

does this sending unit work for "potable water", if not is there one to purchase for potable water? Thanks Len/Deb
This sender is not designed for potable water, only non-potable. We don't have one for potable water.

We have a 10" deep gas tank. what would be the best Reed Switch Sending Unit?I assume its 9" but would like to confirm it. And get the part ordered
Looks like the one that fits 9" tanks is the closest.

My tank is 10-3/4" deep, which gauge should I get?
I would go with the 8" gauge length, that way you know it will fit and when it shows empty you will still have an inch or so of fuel.

I have a 17 1/2 inch deep tank. Which unit should I purchase?
Personally, I would get the 14" sender.that allows plenty of clearance and provides a "Reserve" when the gauge shows Empty.I Don't think the sender should bottom out in the tank.If you do go with the 17 1/2" make sure your measurement is correct so the sender will seal on top of the tank. Remove the old sender and measure the INSIDE tank height.(INSIDE bottom to INSIDE top). Hope this helps!
Can this unit be used for diesel fuel?
I think it will work as it is basically just a float switch-- However, the product description states "For Gasoline Applications Only"---so!!! If you don't want a float type sender I would suggest an "air column type" sender. They have no moving parts & are very accurate. I did not see one in Jamestowns offerings (sorry Jamestown!) but several of the performance boating catalog sites have these senders.I Have used both types in gas applications and both work well but the air column reacts less to sloshing liquid resulting in steadier gauge readings(no bouncy needle).Hope this helps!
I have the 12 gallon topside fuel tank low profile noplace other than the fill cap to install itis there a kit to retrofit this style sending unit to the cap ? thanks jim
Not that I know of
All this sending unit requires is a hole to slide the tube and float through. It surface screws to the are around the hole and the connections are also on the outside. I installed mine where I removed the old ones but I don't see why a location could not be created. To be sure I would contact Moeller, they are very helpful and knowledgeable.
If you have a Moeller Topside fuel tank there is a cap with gauge for either the 12 gal low tank or the 12 gal high tank. Look at Part # MOE-31004-10 on our website.
what fuel gauge do you use with this sender?
Pretty much any electric wires fuel gauge.
It will work with electronic fuel gauges. Moeller and Teleflex models.
How do you measure the fuel tank size. Does it fit in a 6 gallon tank? How do you install it?
Use the chart on the item, for example a 7" unit fits an 8" tank depth, measured from the top to the bottom of the tank. It installs in the top of the tank.
why will my Electrical Reed Switch Fuel Sending Units, workin a gallon container of gas , but will not work in the gas tank? It is not rubbing or binding any place HELP Help Thanks for any rteplies

exactly replaced the original wema sender. jd tech hooked me up with moeller to make sure it was an exact match.

Works great - easy to install. Was able to pivot the tank out t access the unit, so I didn't need to remove the fill line

Fuerl Tank Sending Unit
Was not getting fuel reading on new Faria Gauge that had been installed. Bought sending unit after measuring depth of boat fuel tank and received it in a timely manner. Removed old Sending unit and installed new one....very easy install. Fuel gauge now indicates exact amount of fuel in tank. Great products from Jamestown Distributors. Would highly recommend them to anyone for boating products!

Fixed my problem with fuel gauge!
My fuel gauge on my boat was reading "empty" all the time. I knew I had plenty of fuel in the tank and that the gauge (Faria) was working properly so I figured it was the sending unit in the tank. I shopped around and found one on Jamestown Distributors website that I liked (they had many lengths to choose from depending on depth of tank)at an affordable price and bought it. It was delivered in a timely manner and was installed easily.

Great Service Great Product
Just a great product
Installed and Works perfect; thanks JD!
No swing arm which can get bent or damaged so less down time and will work much longer in my boat.

Great replacement for my old cork float
The installation was very easy. I haven't been able to test on the water due to frozen lakes but so far the sender seems to work like a charm.
