Consider a KEP Subaru conversion that is already CARB certified.  

You don't say how many miles are on this engine, but I'd guess it’s high mileage and may never pass the tests in its current condition.

Before doing anything else have a proper compression test and leak down test done, and then you will know. 

Last, I have no idea how the evap test is done, but if they are pulling a vacuum at the charcoal canister to test fuel system integrity, you may have bad seals on the tanks, including the overflow tanks.

Glad I live in WA, where my '85 is exempt.

Subject: 85 Westfalia Weekender fails Evap test.

I could go on and on about CARB and why they are the bane of my existence..
But I also like my air quality..

Anyway, took the Vanagon to the SMOG shop. They were nice enough to pretest without charging me.

Failed on the EVAP test, this is where they pressurize the fuel system and test for leaks. Any common places where I should look first before going from nose to stern looking for it?

Also failed on the emissions. Previous owner stated that they replaced the catalytic converter. I've done all of the vacuum hoses that I could find.
Complete ignition tune up and timing. I've also got an air-flow meter ordered as the one on the bus has been "compromised" (opened up).

Anything else I should play with?
