For the tank vent it just needs to be higher than the tank. I run a small K&N air cleaner on the end of mine, and it is mounted in the rear axle hump, Mine is an Ebody. What size hoses are you using for feed and return lines? I run a 3/8 feed and 5/8 return, no starvation issues so far.
This is my system.
5/8” return ?!?!
I asked TanksInc and they told me to run dual 3/8" supply and return. I'm wrestling the fuel line out right now because i have welded subframe connectors. Good idea on the K&N filter. I could probably feed something similar through a PCV filter in the same area. I don't want to run it into the trunk because vapors travel
