Pesky Gas Leak

I have a very slow gas leak from the fuel pump glass bowl. It seems that I cannot adjust the nut to the proper tension to stop the leak. I have tightened it, loosened it, etc., and finally left it in the spot where I felt the leak was minimized. It is very slow, and only seems to occur when the car is off and the pump has stopped pumping.

The gasket looks pretty good and I even switched the gasket with the one on my spare pump and I am still getting the slow leak. The leak is not a lot, but it is just enough to be a little stinky in the closed garage. Any suggestions for getting the seal to hold? Is there something I can "coat" the gasket with to get a better seal? I know there are some sorts of greasy lubrication for o-rings and things like that, but since this is in contact with the fuel, I am not sure if there is anything like that that I can use.
 
I had to make a rubber one out of stock rubber from Ace Hardware. It's been leak free for two years. What a pain at first.

I'd be inclined to suggest you order a new one first, then take it from there.
 
Bryan,

Once the cork gasket is compressed (used) in any manner the gasket needs to be replaced. The cork gasket needs to be replaced even if the glass bowl is just loosened and especially when completely removed. I use to carry several of these cork gaskets but since I installed the new fuel pump I have not needed to take it apart yet. The cork gaskets also dry out and get crumbly so store them in a cool dry place.
