Re: A smoggin' I will go...

That's great...all the info on this...I called the dealership with great reserve, but, here tomorrow ~50+ for both sets...grumble grumble, smile, smile.

The silver lining here is that I KNEW beforehand that I needed at least one of the vents and I was waiting to do it before I put my brand new (JY) steel tank skid under there. I just didn't even think about that particular piece flunking my smog test. So now I have another %^!@#$ project...yay!!

Thanks guys!!

It's an 0.050 metered orifice BUT in the Hayne's manual (I know, I know) the .050 orifice is in the small hose. I found mine in the larger hose. I'm befuddled as to it's REAL location. I don't even know if it makes a difference which side it's on. I think it's purpose is to only allow just enough vacuum to clear the tank of fumes or just enough the charcoal cannister can take, even in a "low vacuum" situation as it's not hooked up to the vacuum reservoir and relies only on intake vacuum.

Anyway I replaced the vent/rollover valves, hooked it all up, ready to try smogging again. I only had to drop the tank about 1/2 way to reach the valves.

My original numbers were great, the only snag was the tank pressure:
At idle - CO2=14.4 02=0.3 HC = 32 CO = 0.16
At 2500 RPM - CO2 = 14.5 02 = 0.1 HC = 29 CO = 0.17

Re: A smoggin' I will go...

According to the emissions label the orifice should have the line the runs to the fuel tank, not the line to the intake.

And good luck on the test--don't stay up all night cramming for it, old fart!

Re: A smoggin' I will go...

This old fart passed smog today. Everything was tight. Now I can sleep (except for the numerous spontaneous naps I take throughout the day which my employer doesn't even know about).

Re: A smoggin' I will go...

This old fart passed gas today, but I blamed it on the dog.
