So I’ve got my EFI working right, I vented the fcs into the gas filler vent, seems to have solved most all my issues, except maybe one.
When I’m moving, don’t notice, but at idle with the toll window open, I’m smelling hint of fuel. Changed the vent filter. Guessing this is a 48 year old gas cap, so hoping that will fix my issues.
Thoughts, comments, part number?
I could just order one but think it’ll be easier to go to local auto parts store.
Thanx

how you ended up not loosing a gas cap in 40+ years is pretty good! I think I am on my 3rd now in the past 10.

easy part to change out at local part store. ask for a stant 31722 or crosses to a gates at o'reilies.


Start with that. I have never noticed the gas smell on mine.
