finding a fuel leak (somewhere near/around fuel filter bowl)?

Wondering if anyone might have tips on finding a fuel leak that is coming (i think) from somewhere around the fuel filter bowl. If I watch that area with a flashlight (while engine running) I think that I can see the fuel accumulate, but am having a hard time identifying the source.

Only leaks while running, ends up dripping out tranny dust cover area, pretty steady drip rate. Significant enought that I've lost about 3 - 3.5 MPG.

Any suggestions appreciated.

my bets on the fuel bowl drain valve.

thanks for the tip, I'll try to check out the drain valve again.

Do you have any tips/suggestions on the replacing the valve? I don't know for sure if it is plastic or not, but wonder if it will be problematic to try to swap it out in cold winter temps.
If the ball valve itself isnt the problem you can just get the orings and reuse the valve. I took mine off went to the parts house and couldnt find any orings so I just put the old ones back on and it hasnt leaked a drop since:thumb:
If its real cold and your worried about breaking it just do it after the engine is warm.
