Persistent water intrusion in fuel 19.5 tournament

I'm quite sure its original to the boat - so yes it is most likely the perko combo with vent -- and I will indeed look for an O-ring groove and install one asap.
I am slightly perplexed on how the vent works since the cap appears not to have a vent hole - unless its where you put the deck key
tnx guys very helpful on this problem

The vent is built into the cap and vents "above" where the o-ring seals.

3 psi ? Good to know I would have gone quite a bit more if you hadn’t mentioned that Tnx!
andrew 93 - when I replaced the sender and gasket I did examine those embedded nuts and all seemed ok but see they will be a problem eventually. I seem to be getting a good seal at this point and all the bolts are tightening down well. BUT I like the idea of a stainless blade to strengthen that spot. If you recall where you got that plate please pass me the source Tnx
mustang - I am also beginning to think it might just be condensation from past storage and lack of use. It didn’t make a lot of sense to me to fill the tanks with fuel if I am using portable tanks. Could even be two winters of empty fuel tank.

I ordered from Jegs, but this is the same one. I had to drill new holes in the tank and I used stainless nyloc bolts to secure it in place with a lot of sealant. My tank opening was shot, so next step was to seal up that hole permanently and rely on a fuel flow meter or replace tank. We used it like this for 2 seasons without an issue before we sold the boat disclosing the repair, but honestly that repair was more secure than the OEM.

thanks for that will keep in mind - I just removed and inspected the sensor and rubber gasket on mine again - currently tightens down just fine so at the moment all is good there.
Although I do not like the way water pools in that depression around the sensor opening -- I am about to fill tank again with fuel and go for it. tnx again

"Perko style" is not descriptive - meaning, Perko is a brand and makes different styles... and there are other brands of fills that may/may not look like a Perko.

The "knurled edge" sounds like a Perko brand - it would also have two holes for a gas key, but usually your palm is all that you need. This style does, indeed, have an o-ring near the top of the screw thread portion.

However, the "rubber gasket" sounds different. Go to Perko's website and look at their fills to try and match up what you have. There is a possibility that a previous owner either changed things around or even added that gasket. It's the "previous owner" syndrome... you never know.

Indeed there is a groove for an O-ring on the cap - thank you!
