Fuel line through bulkhead fitting in shock tower?

I just did this yesterday. I mounted it forward as the NHRA rules say that you should not have the regulator or connection within 6 inches of the firewall. It would have been easier where Andy did his. I have 1/2 inch hard line under the car. That is just a gauge not a regulator.

I'm trying to figure out your fuel plumbing. It looks like you have two pressure hoses hooked up to the Sniper and no return line. Is that correct? You should have one pressure line and one return line.
