Author Topic:   Pate Tank Cap

I bought a used Pate 27 gallon tank through the forum and finally got a chance to use it today (the weather in the Northeast has been horrible all spring). I filled the tank to 20 gallons and went to the ramp. The first thing I noticed was that fuel was leaking out from under the cap onto the boat. Not good. I cleaned it up and launched. Typical chop, nothing much. Fuel kept spilling from around the cap. The cap was on as tight as it would go, but still felt kind of loose. Also, there is no vent in either the tank or the cap (like on a plastic Tempo tank cap). Is this normal for the cap? I cant see any way to fill the tank to 27 gallons without a major spill. Kinda defeats the purpose, which makes me believe that it is not normal. What to do? Any help would be most appreciated. Thanks.

I would buy I new cap. My 27 cap never leaked after filling up with 26 gallons. Sounds like the gasket under the cap has gone south. BTW, venting is through the cap. Ken

Bob....the cap gasket must have been lost while cleaning or whatever because it never did much more than a weep when filled. Go to Walmart and get a new cap, they are for lawn mowers.

My 18 Pate came with a Stant Vented Fuel Cap, got a replacement at an auto parts store for $4. (Dont tell em its for a boat, they might double the price!)

The gaskets on the Pates do give up. I tried
a replacemet cap (non-Pate), and eventually
ordered another Pate cap from them. It came
with two gaskets. One of those has given up
and I'm using the second one now. I've got
some gasket material and will just cut my own with a circle template and and an Xacto.

When I was in college, my roommates GF (later
wife) was the daughter of a chem prof. Her
dad had a machine that would cut round flat
gaskets to spec. We fixed a couple of things
on my roomies hand grenade (MGB) with that
machine. Wish I still had access to it.

When I first used my new Pate this year I wondered the same thing. So the first fill was only 24 gallons, no spill. The second fillup 26, no spill. Every fill since is to the tipi-top 27+, never a drop.

It has to be the cap.

Get a replacement, a steel auotmotive type will work for $5 but will rust out in a year or two but it's better than sloshing gas all around and over yor passengers...

My Pate cap "weeps" fuel, making an unsightly stain on the 27 gal. white tank. Has done so since bought new in '04. I thought it was normal. Guess I'll replace the gasket.

Bullbay had some good new info to add. Noproblem with him
resurecting the thread.

My Pate weeps a bit when the gasket is getting tired. And its
been weeping lately. I might try a Napa, just for grins.

If the cap isn't vented, how does a partial vacuum not get formed as fuel is drawn? (eventually stopping the fuel flow)

The Pate cap is vented.

The gas caps on my garden tools have a little rubber "duck
bill" valve that works kind of like those rubber scupper
