Emissions. 86' GMC, what am i missing? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok i figure its getting old me posting about my crappy emissions.

Im just missing a couple things.

I got Air Pump...Air Pump Belt and the hose that comes off the air pump at the end of that is a Tee connector.

I picked up a a air pump check valve and i got 2 air pipes 1 for each side.

what else am i missing?

The air check valve has one end that has threads in it and the other end looks like ya use a hose clamp to keep it on. So i think im missing whats between the tee and the air manifolds.

Anyone got a checklist of emissions. And dont say order a LMC catalog cause i already did :p

do you have the thermostat housing with the plastic thing with all the small hoses?

BladeX · 01-03-2004, 09:05 PM

i think so. if its the saucer lookin thing with like 5 hoses coming off it then yes

and yes im a n00b. lol

I got the pump all instaed and the thing blows air. i just dont know what i need to connect the rubber house that has a plastic 3 way tee on the end of it to the Air pipes that are on the exhaust manifolds. Plus i have a air pump check valve not sure where that goes.
