I swap in the original non-leaded filler once every two years when I get it smogged.
Does it swap right in without issue? I was thinking of doing that, but could of sworn someone had said it wouldnt work.
I had thought of pulling mine off and having someone weld in that restrictor

Which of these would I order?
