Question about Vapor Canister Lines

[SaltyMike]

After having done a Weber conversion for my ‘82 Brat, there is a vapor canister located in the front of the engine bay driver’s side with four lines coming off of it. I was able to cap off three of the lines that once went to the old carburetor, but there’s a fourth line that appears to go into the firewall right near the fuel filter that’s underneath the hood. Does anybody know what this line is/does and if it’s safe for me to delete?

That one goes to the fuel tank.   The whole reason that system is there is to collect the fuel vapors, and let them get burned in the engine.

Okay I see, thank you very much!

did you hook up PCV hoses to a standard air filter casing seen on Weber conversions? I have always hated the way the filter element inner rib seal loses it's seal to make way for a 10/mm inlet ID right under the corner that seems to be blocked by about 50%. An absolute pet hate- sorry. I tossed a redline fitting due to its wear and tear over the decades, filter and plates will be next. Got a Pierce style or original cast, finned plenum to do remote filter. Comes with a bigger filter mounting area so not a pain to get PCV in if going in at this point. I will likely feed in at remote air filter box.

Hey! My apologies for such a delayed response. Life has been super busy and haven't been able to browse the forums much as of recent. But yes I did hook up the PCV hoses to the air filter that came with my Weber kit. I used a plastic tee-pipe fitting to route bouth lines into the air filter. Luckily I haven't had any kind of major problems with seals related to the air filter going bad. I will be doing an EJ conversion in the near future so the air filter won't be a potential problem for much longer.
