Its not a must have. I just ran the gas tanks vent line into part of my intake. Idk how good of an idea that was though, could a narley backfire do some damage with this setup? I had a few with no issues.
I never came across that problem there, hmmm. Guess I just got lucky everytime. And I know you lived in richmond, Ive been to your place. This is Michael Lamberson btw. Howve you been?
