Evap Line, Check valve?
Hi Guys, just a quick question.
I've been looking at the evap line off the back of the inlet plenum & wondering if a check valve is needed post evap canister purge volume control solenoid valve.
From my reckoning the solenoid valve in the line opens & closes as requested by the ecu to release vacuum built up in the Evap Canister.
No idea when exactly that happens & figured it probably wouldn't be real happy if it purged while under boost.
Not something i've ever heard anyone mention so its probably a non issue.
Just thought i'd ask.
Cheers.
