I have no idea. It's what came with the kit.

They're commonly used with throttle body fuel injection kits. The El Camino had one with the Holley throttle body fuel injection kit. Holley recommends a separate fuel pressure regulator to dial in the correct pressure required by the injectors.

That looks like the kit I got from Bouchillon when I built my Charger. I too tried that Corvette fuel filter / regulator. It was the only GM part on my 6.1 install. My engine must have know it and rejected it immediately. They are designed to regulate the fuel pressure at 58 psi but my engine didn't like what ever it was supplying. i ended up tossing the GM piece and installed an inline fuel filter in its place and bought an adjustable fuel regulator with a gauge and return. Much better setup IMO. Not sure why you needed to run the lines on the driver side though. Mine worked best on the passenger side. Here is a pic showing the regulator

On my 392, the fuel line connector is on the driver's side (under the red cap)....

My setup will look like this one below (seen at Carlisle last summer) and there's a lot going on the right side with the computer location, heater hoses, and the tight clearances against the firewall, so it was just as easy to route the fuel lines on the left side of the car.

Gotcha.....I hope that GM fuel filter/regulator works for you. Maybe mine was just a fluke but I am happier with the adjustable regulator and gauge.
