So my 74 javelin amx has a skinny steel line that's probably about 1/8 inch thick. It runs from the tank, to what looks like a filter right next to the tank, and then up along the frame to the engine compartment. It is broke off right underneath the brake booster so I cannot tell where it was supposed to originally go. What can be done with the vent line if I don't care about all the emission garbage? Can it just be spliced with a rubber hose and linked directly to the carb vacuum port? Also, if it is indeed just a vent line, why does it run through through a filter? You would think only the actual fuel line would have a filter. Anyone dealt with this before!?
