Fuel problems 1983 228

[JackT]

Recent purchase, 6/9/2018, of a 1983 228.

Finding water in fuel. Had the fuel in the tank professionally cleaned twice.

I think the water is making its way into the tank during rain. Boat is currently stored uncovered. Heavy rains lately.

How would water enter the fuel tank. Hole in top of tank?

Pull the inspection plate under the console. It might be getting in at the fill tube?

The 228 I have has a small inspection port to access the fuel sending unit towards the cuddy cabin. I have pulled that off as well as the entire cover for the coffin. The foam looks like hell but is firm. Water sits on top of the tank. I put a new fuel sending unit in as well as a new gasket. No obvious pointy of entry. Water getting in around the tank seems to be built into the design.

Possibly the O-Ring on the fuel fill is either bad or not tight enough. The water can be running down the gunnel and funneling in.

Brian, Thanks

So the black plastic screw-in 1 1/4" cap is suppose to have an O ring?

Mine does not but appears to not require one. Am I wrong?

[Burger]

Definitely needs an oring!

Will start there, thanks.

Does anybody have any ideas or thoughts on how to pressure test fuel tank/system in place?

The cap actually did have an o-ring. Replaced it anyway.Any other tips?

If the tank is original, and as you say there is water on top of it, there is a very good chance the tank is compromised.

Could also be in the fuel fill area too.

[JackT]

Tank failure is the conclusion I'm coming up with. Its a lot of water.

What should it cost to have that done?

[JackT]

Nobody knows?
