Fuel tank vent
While doing my single turbo conversion I have a few things I'm still figuring out. One of them is the fuel tank vent that runs with the feed and return lines up to the firewall. From what the research I have done most of the results that came up were for the older cars. Obviously it's all relative and the same info would generally apply to FD's but I wanted to get people I put as to what they did with this line on their single turbo set ups.

I'm not sure what I'm doing with it yet, I removed all the vac hoses along with with the hardlines that were between the injectors and hoses on the fire wall. So I'm not exactly sure what my plan is yet.

Since you've started tearing stuff up, two suggestions:
1. Put the charcoal canister and PCV system back to stock.
2. Failing #1, tie the fuel tank vent into a charcoal canister, then vent the charcoal canister to the engine crank case. Then connect a check valve between the upper crank case vent and vacuum nipple on manifold. This assumes a standalone ECU.
