hanomon Posted July 25, 2013 Share Posted July 25, 2013 (edited) Got a 94' corvette LT1 in a 75' 280 & redoing the wiring harness. Not running any emissons so we removed the EGR vacuum solenoid. However there is another vacuum solenoid on the passenger's side. The service manual says it's for canister purge? The Mitchell diagram lists it as "Evap canister purge" off the ECM's Blue clip-pin #10 dark green wire. I have it connected to the stock Datsun vacuum line to the charcoal canister from the fuel vapor collector tank. My question is; what actually triggers that solenoid or is it even necessary? Could we just remove it and run our fuel vapor canister straight into the intake manifold? Edited July 26, 2013 by hanomon Quote Link to comment Share on other sites More sharing options...
hanomon Posted July 26, 2013 Author Share Posted July 26, 2013 Found a emissions diagram on shbox.com for that solenoid, so looks like we're ok with the set up as is. Quote Link to comment Share on other sites More sharing options...
