friend of mine is about done with his blazer and just asked if I could find one. I'm not exactly sure which lines he's doing. I don't think they have alot of vac. accessories, am I right. He has the distributor and the power brakes hooked up, but I'm not sure what else needs vacume.

well there is the distributor, TCS solenoid, smog pump, charcol canister, charcol canister control valve, booster, PVC, vacumm guage, TAC module, A/C, transmission, choke diaphram, and uh. i think i got them all... I kinda know where they all go except maybe the guage.

When I put my blazer back together I found everything I needed in the service manuals.
A/C controlls and all.

no, he doesn't have a smog pump. He pretty much has just a basic 350 w/o any smog stuff on it. I think he has a service manual, which one do y'all use, or is there only one?

if your running an after market carb w/o any emmissions stuff or a/c....all you need is pcv, brakes and vac advance. that's as bare boned as it gets.
