Hello fellow gearheads! New forum member here and new to me 2004 Corvette base model. Purchased my little beauty about month and half ago and love it. 42k miles, I’ve already replaced shocks with C6 Z06 stock shock and that was a nice improvement.
Of course about a week after driving off the dealer lot the check engine light went off.. did the gas cap and nothing, then before throwing more money at it tested the solenoids and both were working. While the purge valve was out (top of the engine) I inspected the hard plastic pipes and the curvy crinkly one turned out to having large crack, from age possibly? Anyway I replaced it with a thick fuel hose and hope that is ok. A few miles down the road later check engine light turned off, yay! Just throwing this out there for those working on this problem.
learning a lot on this awesome forum, thanks!
Good question! It is a very stout reinforced hose and I'm not able to pinch it closed myself and I could only get my mini vac to pull 15-20 psi with no movement in the hose. I don't know how much vacuum the evap system pulls? With engine fully warmed up and several miles the light has not returned so must not have pull closed at this time anyway.

EVAP system uses vacuum provided by the engine. I assume you meant 15-20 in Hg.....not PSI? If you could not collapse the hose with 20 in Hg.....it should be fine.
