2001 dodge ram , 4x4 , quad cab

Check engine lights on
Code- 40442 Evap leak
Bought a new gas cap
Cleared code
Code came back
Checked gas tank filler neck, looks fine
Check evap canister lines,etc they look fine

Is their any test i can do to check, or any common place that lines goes bad that i can look for?

check the rubber vac lines at the purge solenoid on passenger side fender - cut off the split ends.

check the vac lines on top of the cannister and replace.

That should be in the FAQ section.
