Have some questions on some of the late model civics about the purge valve on the canister, I'm building a system to vent the SU carburetors, on my 86 Accord, I'm trying to figure out which of the late model civics have a canister with a hose on each side of the purge valve, do these valves just open with 12 volts? Of course they are designed for fuel vapor, so thats no an issue, I'm trying to figure out which one will work, and verifying the function of them,before I go hunting one at the yard
