This is probably what you are looking for,but you should pull the original one and compare.
Hmmm.
Most the ones I looked at... Sierra, Seasense, etc on Amazon, eBay or most parts websites were 240-33ohms. I ordered one from Amazon that came up when I searched UFW-6.5.
I found this same sensor (with clearer markings) used on similar sized & powered boats.
For $30 I'll find out at the end of the week.
Right now I'm a little more baffled why I ran out of gas at all. All the specs I've seen for my boat say it has a 30 gallon tank. After I got towed back to dock I put all the gas I had into the tank--2 5-gal cans + maybe 12 gallons in my gas caddy. Total 22gals at most.
After cranking a few seconds it started. I went for a quick spin.
When I pulled the sender I found the gas level tickling the top of tank.
What else could I look at to explain running out of gas with possibly 8 gallons still in there? What kind of fuel pickup is (was) used on a basic carbureted engine in 2000? Should/could I suction ALL the gas out and carefully measure how much it takes to reach the top of the tank?
