Large Evap Leak Help!
So I'm bored and sick of staring at my CEL so how can I find the source of my large evap leak without a smoker?

I'd try this: Pull the return line, put about 5# air pressure behind it with an air compressor and blow nozzle, and start listening for a whistle. Or start spraying with soapy water and look for bubbles.
Likely spots are the leak detection pump and associated tubing and the evap lines and canister.

UPDATE:
Used the blow gun method and found my leak. Behind the intake manifold there is a 2 1/2" piece of 5/16" fuel hose connecting the plastic evap pipe to the steel one. It looked as though someone went to town on it with a razor blade it was so cracked. Swapped it out and have had no CEL yet!

I had done a visual on almost every inch of hose and lines on,in and under my 01 XJ. I reset it and I'm pretty sure that was it. Won't miss that CEL!
THanks man!
