Ahh ok. Are you saying just cap off one of the fuel rails outlets on the firewall side? Then use a crossover tube in the front then one line on the firewall side back to the corvette regulator then 2 lines into the supply and return at the tank?

Ahh ok, just saw this post. Thank you

Here is a picture of how it can be done. It's the simplest and most effective way todo your fuel system. You will have zero issues if you do it this way.

As Jody mentions, the VaporWorx setup is also an option. For your 5.3 it could be used if you wanted to. They have a system for an NA setup like yours. https://aeromotiveinc.com/pages/vapo...Mj9JW94UMZBMGC

I run that on my supercharged LSA Camaro as I need more fuel pressure than the Corvette Regulator can provide. So easy to install, works amazingly, and the pre- and post-support is top-notch.

Got it, thanks.

Thank you for all the good advice.

If you use the corvette FPR only use AC Delco or Wix. The rest are garbage and can’t be relied on.

Best option for fuel line long term is a hard line front to rear with the AN line to the tank and to the rails. Runs along the stock path. Couple clamps to hold it down and away from vibration or heat sources.

I use the Right Stuff line and cut and flare it for AN. One cut and flare near the tank. AN adapters for feed to the regulator. AN lines to the tank from the regulator. Another cut and flare near the passenger footwell area by the subframe. AN line to the fuel rail.

I buy the Fragola premade AN lines to make my life easy. Leak free everytime. No AN lines to make that I have to pressure test for leaks. I do pressure test the entire system and blow it out before I run gas thru it.

What size Right Stuff fuel line do you run? I see they offer 5/16" and 3/8".

Normally 3/8 feed and 5/16 return.

Ok, so the feed line from tank to regulator is 3/8? Then the return from regulator to tank is 5/16? Then what size from regulator to fuel rails (passenger side floor board), (5/16" or 3/8")? Sorry for all the questions, this is my first time doing the LS stuff my last build I did all stock stuff.
