So first thing that we needed to figure out was how to get rid of the old car gas smell.
First up replace the gas cap. The tank I received from Goodmark was for a 71 and up and the cap we had was for a 70. I big thank you goes to the guys at Goodmark for helping me figure this out.
Next up was a filter/vent on a budget.
So 2 months later and no smell. Sometimes budget fixes work great
