Fuel Leak

Okay, so I am already thinking through all of this but I am looking for experience to help. I hooked up all my fuel lines today and then turned on the gas. no leaks at the tank. :) but then I turned the gas on and fuel came out of the top of my sediment bulb. I have a glass aftermarket kit and no matter how much I tightened up that bottom screw it just kept overflowing. I have the screen in, the rubber gasket in and I am wondering if anyone else has had experience with this issue as well. is there a defect that you have noticed? let me know. Thanks.

I'd use a cork gasket, and make it about 1/8" thick. If you only have a sheet of 1/16" cork, just double the gasket.
 
check the seating rim within the top hasn't got any gunge on it. A smear of blue hermatite ( but perhaps that a UK only product- gas sealant anyway) may help. When rebuilding SU carburettors we used to soak the cork gakets in oil overnight to make them somewhat softer and hence more accomodating.
 
I agree with John, soaking the gasket first makes a world of difference when using cork. Also check under sealing rim of metal top of sediment bowl for any die-cast sprue's when dealing with any aftermarket die-cast parts. A pen knife or even a dremel grinder,(very carefully) may be needed, but I'll bet it's the gasket.
 
you shouldn't have to put too much pressure on that bowl. the one i have (carter) seats good with a little more than finger tight.
i suggest removing the gasket for inspection.
sure cork is easier to cut. but if it came with rubber or a like rubber gasket. wouldn't that be a first choice to replace with.
also with cork, as with any gasket recommended to soak prior .
i've been told to soak it in what ever you plan to stop.
fuel may be an exception here.
