I have an obd1 jdm b18c1 in a '95 ls teg. I'm using the jdm p72 ecu. I installed the evap purge solenoid from the b18b before I learned that the jdm ecu doesn't control it. Was thinking this might not be good since the fuel tank vapors won't be purged from the charcoal canister.
What's the best way to run evap? I don't have to worry about smog.



Should I connect hose #3 directly to the intake manifold (where #19 connects), bypassing the evap solenoid?

Or



Should I disconnect hose #53 from the charcoal canister and let it vent to atmosphere?
