I have a 74' f.5 with a weber carb. I was hoping to put this off for a while, but I noticed when putting fuel in the tank for the first time yesterday there was a lot of negative pressure in the tank when I took the gas cap off, so i started reading the threads and I did not want to go the vented gas cap route since the charcoal canister is still in the system. In following the wiring I noticed the VSV is not functioning and has some, but not all, wires connected. Pictures to follow, but my questions are:
1. Can I take the feed from the charcoal canister that used to feed the VSV and put it directly on the intake manifold? - is this safe, will this allow my tank to pull pressure back and fumes to go where they need to or is there a better way?
2. There are two lines that go from the front of vehicle facing side of the vsv to a junction on the intake manifold- Remove and plug?
3. All the lines in the system, specifically the lines above the tank look super old- what is the priority to replace?
4. Under the vehicle at the front of the leaf sprint is what I think is a fuel filter or a check valve. How to tell the difference?
And as always, if you see something glaring that needs to be addressed- feel free to let me know (I know you will anyway!).
