I need to replace the fuel sending unit on my 2002 192 Tournament. I am going to go with a Wema sending unit. Has anyone replaced theirs on a 192 Tournament and if so, can you tell me the correct length or a part number? Many thanks.

Call GW customer service and they will tell you the depth of the tank. Subtract 1/2" and order your sender from WEMA to that length.

Do me a favor please. When you pull the old unit, measure from the flange to the tank bottom. I usually subtract an inch for the sender length and am curious what Grady did.
Thanks
Just for reference, my 1992 190 Tournament has a factory gas tank of exactly 9.50” depth at the sender port. My local Grady dealer sold me a 8” a few years ago, but would’ve been happier with a 9”
My understanding is that the guideline is 1 inch shorter than the depth. I believe that is WEMA's recommendation. The senders come in whole inches so I see what they sold you an 8. It really doesn't matter very much. It just means that in theory, when your gauge reads empty, you have a bit more gas left than if you had a 9 inch sender.
In a really hypothetical model of an 80 gallon tank that is flat sided and flat bottomed and that when full makes the sender read full, each inch of gas depth represents about 8.4 gallons. So in your case the sender reads empty when there is still 1.5 inches of fuel left or about 12.6 gallons. If you had the 9 inch model, empty would mean about 4.2 gallons left. Of course this is not a realistic model if you tank is slopped on the bottom or sides but regardless, I would rather have 12 gallons of gas left when the gauge reads empty as opposed to 4 or so. As long as you have a feel for what the readings mean, the length is super critical One other advantage to the shorter sender is that there is less chance of it sucking up gunk or garbage that has settled on the bottom.

I've had 8" and 9" senders in my 96 192, and I think the 9" gives better information. I did a fill test and the 9" sender was still reading empty when the tank had 10 gallons.
Using the math above, the 8" would bump the empty reading to about 20 gallons, or a third of a tank. That's in-line with what I saw with the 8", and that's why I switched back to 9".

I went with a KUS USA Fuel and water sensor 9 inch 4 years ago and no issues at all
Good Morning, where did you order the sending unit from. I'm in Canada but no one seems to carry it. Any outfitters I see want stupid money to ship into Canada.
One place was $42.40 and $140 fuel surcharge. I often have things shipped to Buffalo and make a day trip for wings and pick the stuff up. Thanks

Try contacting KUS and ask them if there's a retailer in Canada. Or check with your local marina or marine store - that, I think, should alleviate the shipping issue.

It was a little hard to find here in the US too. I ended up buying it on eBay for $44 + $10 shipping.
KUS 151330 SSS - 9 inch Single Station Sender Fuel Sender, Liquid Level Sender | eBay
Original KUS. SSS 9″ FUEL/WATER SAE 5 HOLE 316 ST/ST SENDER. It is based in ABYC standard, and are non-linear. Provides a more precise tank level reading than swing arm senders by greatly reducing slosh fluctuation.

Amazon, we have family in Canada and often send things there so should be no problem for you. I replaced mine 4 yrs ago with Kus USA SSS Fuel & Water Level Sensor 9 inch $55

I just acted like I was sending it my family in Canada shipping was $9.95
I replaced the unit in my 242 and had a lot of trouble. Ordered the Grady recommended USA unit, but the one I got was mis labeled a European unit. The dealer did make it right after proving that I tested it properly. I noticed the other day that Sea Star ( I think the brand) sells a universal unit that you cut to length. It was on the shelf at a dealers shop. Good luck, hope you get the right one the first time.

pickup?The sender has to have some clearance from its pickup to the tank bottom. Therefore it will always read empty when there is some gas in the tank.
What gas gauge do you have. The command ling gauges don't exactly tell you when the tank is empty especially if you have a rod type sender and not a swing arm type.
Finally, the angle of the hull in the water make a big difference in what level the sender reads. As the stern tilts deeper or he bow tips up, the reading can differ from actual by quite a lot.
I look at the gauge reading as a suggestion. It is better to learn what yours reads under different situation and also be aware of your typical burn rates

I read it and thought I was having a senior moment. Then I realized YOU had the senior moment.
