I launched for the season a couple of days ago and yesterday I noticed gas fumes in the engine compartment. I identified the culprit as gas leaking around the gasket at the top of the fuel bowl. Figured that the old gasket dried out so I tried a new rubber gasket from Tractor Supply meant for an antique tractor, but it did not work so I have ordered some cork ones from Jim Staib. My question is with the top of the fuel bowl which has a raised lip around the perimeter. My assumption is that it was meant to hold a 1 7/8" OD gasket in place but it seems that with this raised lip the gasket does not have much compression against the housing. Anyone else have any experience with this situation? Also the screen was between the gasket and the housing which I assume is correct. ---

As I recall. The gasket fits in the metal part of the pump, and the compression because its cork makes it tight. Hopefully someone has a photo or diagram of it all. The Willys has the same thing BTW. ---

One thing that can and does happen is that the cast housing can become warped from overtightening the bail screw. Might be possible to straighten that, but I’ve never attempted to go that way. ---

Fortunately, the housing is now warped. I have had this boat for 9 years without this problem so hopefully the new gaskets will work. A 2" OD gasket will fit into the housing and the bowl is 2" wide so I’m still not sure the purpose of the upturned lip on the bowl. ![Fuel B](https://europe1.discourse-cdn.com/flex017/uploads/oldboatshome/original/1X/1757918d3e56adb9c932ff343bd28f11c2f3b4c2.jpeg) ![Fuel Pump A](https://europe1.discourse-cdn.com/flex017/uploads/oldboatshome/original/1X/d166bd954c927fdf70dc363db9cf665801b8293d.jpeg) ---

Sorry - the housing is Not warped! ---

We are all warped! its the rest of the world that is wrong. HA, Yes a thicker gasket, cork, should work. I honestly think if it stops a leaking, it works. Trial and error. What could possibly go wrong? ---

Update - I received the new 2" OD gaskets from Jim Staib [great guy - I highly recommend for parts] and it worked. I’m still not sure of the reason for the upturned leg on the glass bowl but that’s what you get with classic boats.
