Default Evaporation Leak

I have an evap leak somewhere on the 200sx. I've inspected the charcoal box and the lines around it and can't really see any cracks or leak areas. How would I go about finding this leak? It is keeping my CEL light on.

I also assume this is contributing to my pitiful 22mpg.

I would usually start with the Tank. Drop the tank and inspect the evap lines in the rear also check the filler neck for leaks.

If possible, smoke the tank.

Dropping the tank sounds difficult. Is it something I could do in my own garage?

Also, I've heard about this smoking thing. How much would a mechanic charge for something like that?

I charge 100.00 when I had a machine but that was for the whole Diag not just the smoke. If I was getting the Diag it wasn't worth doing.
