Converting from carb to efi in california, charcoal canister
 

I am installing msd atomic efi tbi in my 1986 c 10 i live in california so must keep all emmisions and smog stuff, the charcoal canister in my truck now is for a carbureted engine and has several hose there is one for the carb bowl vent, the efi does not have a connection for this hose, should i just get a canister for an 1987 tbi truck that way i wont have a hose not hooked up for the smog natzies ? Also thete is only one large manifold port on the efi i need 2 large ports one for the brake booster and one for the pcv valve any suggestions on that

For the PVC, just get the appropriate plumbing to add the 2nd port. Most manifold ports are 3/8 pipe thread IIRC.

For the canister, if the MSD system is a CARB approved substitute for a carburetor, the MSD support site should have an approved way to properly handle the carb vent hose.

I used an 87+ TBI canister in my truck and hooked the line up to ported vacuum so that it only pulls fumes under throttle.

Call your local smog refere, if u are trying to keep it legal they may have a few hoops you to jump threw.

Are you talking about drilling and tapping a hole in the manifold? I have heard of that but wasnt to keen on that idea

More like a short nipple, tee, and whatever magic fittings needed for the pcv hose and brake connection. This assumes your single manifold port is threaded.

Ok i can hook the brake booster to the port on the actual manifold and pcv to the port on the bottom of efi then
