Pcv hook up on FI Tech go street efi system

On the back of mine, the largest port is on the passenger side and I used that one for the PCV. I'm not sure if that draws above or below the throttle blades, or evenly from both sides, but I don't see any plug fouling or buildup from oil mist. moving toward the passenger side, I used the next small port for the fuel pressure regulator on the FCC. The last port I just have capped as I run manual discs. I also capped the forward port. Mine is an early model, still running the original version 1 software and original version of the FCC. I started to get a little lean stumble a WOT and decided to do the FCC mod to be a full return vs vent. Upon opening the FCC I discovered the short fuel line connecting the pump to the outlet fitting on the top cover had loosened, and the zip ties securing the pump worked loose. I retightened the fuel line, retightened the zip ties, and removed the float valve and the brass filter. Unfortunately I had just T'd the vent into my filler neck vent, and after about 20sec, the fuel would be forced out the vent onto the ground. I replaced the float valve and luckily the lean stumble has been resolved from tightening the fuel pump line. The FCCv2 looks pretty nice. I plan on reaching out to FiTech and purchasing the vent line bung they supply with the FCCv2 so I can go full return vs deadhead.

As for air cleaner clearance, I have seen guys using the banjo style fittings with success..
