Replacement part no longer made by GM.

Best to just buy one at a auto part store and chang it yourself or any regular shop should be able to do it cheaply ..its common gotta get the old one off and bring it in to get the right size but its cheap usually about $5 to $10 they sell it by the foot not sure how much youl need but they can cut whever length you need of you never changed the gas cap you might want to look at that too most evap leaks are simply be uas of an old gas cap....anyway good luck hope this helps

Mechtrix,

thx for the reply !!

addressing a couple of points...

-> technician at the chevy place outright stated there is no replacement available. None from GM as they changed design and quit making the old ones appx 3 yrs ago.

-> The repair receptionist stated she looked for anything that offered it as an aftermarket approved by GM as being feasible. I confirmed this at home before I posted the original question. All the usual car parts online shops noted for that old of a Chevy spark, there was nada/zio/etc that would work.

Now being bold, I look at reddit car repair forums a bit. Best advice they gave was to try and repair.. or disable the EVAP solenoid completely. Ummm no on the disable.

have looking through auto savage forums. no bueno.

so, looks I drive it until it won't start completely .. or spend some coin on a diffwrent vehicle.
