…finished my refresh of a 1992 yj that I started in April 2021. As part of the refresh I put in a new fuel pump, which was a lot of fun…not. Last week I took it for a smog and it failed for an “evaporative system leak.” Turns out it was the fuel tank vents…I should have replaced these when the tank was out for the fuel pump. Fuel tank came out for a second time and I replaced the vents/seals (relatively cheap parts) Consider changes the vents if you ever have the fuel tank out. Happy ending is that my rig is now smogged and ready to hit the road!
