Routing Vacuum Lines
I have a 1990 Honda Civic EF using the D16A6 engine type.
I have deleted the "Charcoal Canister" and the "Purge Cut-Off Solenoid Valve".
What is the correct way to route vacuum back to the "MAP Sensor". What ports need to be capped or vented to atmosphere to operate correctly? Thank you .

Re: Routing Vacuum Lines
vacuum hose no. 21 from the front of the throttle body to the MAP sensor needs to stay - don't do anything
vacuum hose no. 12 from intake manifold to purge solenoid - delete - cap nipple on back of the manifold where hose was removed
vacuum hose no. 7 from purge solenoid to canister - delete along with solenoid and canister
hose from canister where it says "to two-way valve" runs from canister to steel vent line coming out of firewall - delete the hose, but leave the steel vent line uncapped

Re: Routing Vacuum Lines
Gotcha. Just be aware that line poking out of the firewall will be venting fuel vapor into your engine bay. I'm not sure how race cars account for this. It also flows the other direction in that it breaths fresh air into the tank as the fuel level drops.
