Time for the 2 year emissions test. Pull the timing back to 5 deg btdc, adjust the idle back down to 700 rpm, should be good to go...
Well, it passes the rolling sniff check with flying colors. Its a 60-over 345 with a mild comp cam, qjet, cat, single exhaust. They do a chassis dyno kind of rolling test that is really lame. Testing the emissions at 15 mph, and 25 mph. What does that prove? Why not run it up to real world conditions? Say 35/65 mph?
Anyway, it passes:
hydrocarbons- 38ppm. Max allowed- 189ppm.
Co%- 0.00% max allowed-1.33%
nox-903ppm. Max allowed- 1448ppm.
So now on to the part where they pressurize the tank and the cap. The cap passes, the tank fails. He does it 3 times, and I checked his work. The adapter was correct for the application, and it seemed tight. I heard no nitrogen escaping around the cap area. But my hearing isn't so good.
Without knowing which hose was bad, it was time to drop the tank and replace everything. And just fyi, the 2" filler neck hose isn't cheap. It has to be fuel rated. A 1 foot piece at auto zone was over $20 when all said and done. The pics show what 1979 hoses look like when they spend their whole live in so cal. For those of you that actually have a winter, yours are probably worse. But you probably don't have the air nazis up your ass either.
I assume the a po installed the 33 gal tank. Its been bounced off some rocks, but there was no rust and no leaks, so after sanding and wire-brushing I swabbed on some rustoleum red lead, and rattle canned it black again. I left the square nut the po used from his erector set on the fuel sender just for posterity. Should be good for another 30 years. By then it'll be someone else's problem.
