Fuel sender valve and gasket

[ReedH]

Hi everyone, have a question on some rudimentary help wanted. Anyone have experience removing the KUS fuel sender? Have a 2001 265 Express and appears the gasket may have blown as fumes are pretty strong in the cabin and I’ve ruled out almost everything else. I picked up a new gasket kit. When I’m looking at the fuel sender it appears like there’s no way to remove the screws to take out the sender. The screws appear to be under the valve cap which does not appear to be removable otherwise? Appreciate any and all thoughts/experience.

please disregard…not intuitive but the unit was a “screw off” type then remove. Difficult but figured it out!

I was going to say on my new tanks they are threaded and there are no screws and no gasket.

Unfortunately that leaves you still looking for the source of fumes.

Remove the deck and the tacklebox under the bait sink and the drawers in the cabin to get a look at everything.

20 years is hard on hoses and aluminum tanks.

Calling it a "Valve" is confusing too. The sending unit is a sensor. The valves direct fuel flow from main/aux tanks. They can leak also...

Did this start after fueling the boat? If so it could be hoses.

Good chance that its a leaking tank. Check the bilge water and sniff for fuel. Lift the deck and carefully use a plastic bilge bailing hand pump to sample fluid in fuel tank compartment.

Numerous posts here discuss fuel tank issues.

As alluded to, you haven't eliminated everything unless you pulled the tank out. Most leaks start on the underside where you can't see them easily.
That said, it would help to know where you smell the fumes ( for example, everywhere but stronger if you pull the deck plate and sniff or not as strong at the access plate hole) and as also mentioned, if the smell is stronger after fueling and if so, do you fill the tank until the nozzle clicks.
Leaky and maybe somewhat porous full and vent lines will cause more of an odor after fueling.

I replaced the senders in my 265 last year. Totally destroyed the Rivnuts holding the screws in, had to replace about 5 of them. Be careful with them. Self-inflicted SNAFU, for sure.
