Water in my petrol tank !

[Angus gentleman]

I keep getting water in my tank ! Drain is clear and rubber seal seems ok ! But when I open the cap after rain you can see water around the filler hole ! Any ideas ????

Can you see the drain hole on the left?  Sometimes the cap gets screwed down upside down and the drain hole is on the right but when it's over there it doesn't line up with the drain hose.

+1 what Wayne said.

Also, there is a foam rubber gasket in the lid of the gas cap. Maybe yours needs to be replaced. They make a kit to replace the gaskets and seals in your gas cap. I think it runs about $15 bucks, if still available.

Update:

Part #16 11 9 062 461, Price: $30.00 US

There also is a gasket that fits between the tank and fuel cap assembly. Part # 16 11 1 453 690. Are you missing this?

I've checked the drain replaced the 2 seals !

Just ran across this rebuild vid and thought of your post if you haven't fully resolved the problem this may help. Lot more seals in there then I realized. 2 O rings, Foam gasket (likely you leak) and a large O ring.
Good Vids but Chris is a bit colorful with the language. Get the kiddies out of ear shot if you have them or you may have some words from momma. ;)
