evap leak
 

Have a 2005 silverado. Changed the fuel cap,purge solenoid,and vent valve.Still getting evap leak .Anything else I should look at? :confused:
Also had the system sknoed but did not see anything

Top of the fuel pump sender assembly rusted out? I've seen that before where you get a tiny pinhole in the rusty fuel pump assembly causing a leak. Leaking canister? Broken plastic line, etc.
