I have a SBC in my car, mechanical fuel pump with holley carb. I just removed the in tank electric pump, put a piece of 3/8 pipe with new sock in its place.

What is the proper thing to do with the vapor canister line. I think i cut it off and its wide open in the tranny tunnel somewhere if I can remember right.

It seems I've always had a gas smell in the garage when car is parked for a long time.

What is the best thing to do with this line, some say plug it, some say put a filter on it.

what about plugging it and getting a vented gas cap, looking for simple and effective here.

 

i plugged mine and went with a vented gas cap.

 

I used the same vents that they use for rear ends.

 

where did you get the vented gas cap

 

i bought a new locking one at autozone. was under $20 IIRC?

 

I believe there are short hose connections on all lines above rear axle on drivers side.You probably can ID the lines and make a cap for vent line at that location.My 84 carbed Z 28 has these lines at that location ....not sure on yours....but you could at least take a look. Good Luck.
