Well, that doesn't make a lot of sense. There shouldn't be fuel getting anywhere near that pump rod shaft. The wet side of that arrangement is the pump cup "well" next to that. Even a bad top gasket, you wouldn't think, would cause fuel in the pump rod shaft.
I used "nylon" washers on the two float bowl access plugs. Think I got them from charlie price's vintage speed shop years ago.
The "regular" gaskets usually supplied in a carb kit for those two locations frequently weep. (Even my Edelbrock 94 leaked there, right out of the box and brand new)

You frequently see comments about folks getting rid of 94's in favor of the Stromberg unit. My 94 doesn't usually have issues, so I stuck with it.
