A friend of mine bought a 51 willys wagon and when he got it home he noticed a tuna can hanging from the draft tube with wires with screws mounted to the draft tube and tuna can. He said the owner did not like the small oil/condensation drops on his concrete but said nothing about the smell. I told him to check to make sure he did not put a carbon filter in the tube.

Here's a good article. Draft Tube Upgrage

"As I lay rubber down the street, I pray for traction I can keep, but if I spin and begin to slide, please dear God protect my sweet ride." -Amen
