Hey Todd, I just ordered and received 2X Holley 12-308 Fuel Pump modules for a K20 I'm building. Just letting you know that the website has these listed at 5/16" supply line and 1/4" vent line, when they are actually 3/8" supply and 5/16" vent.

Thanks for pointing out that incorrect information Nick. I don’t have any involvement with the EFI side of the business, but I’ll be sure to pass along the information to someone who deals with those products.

No worries. I actually have one more question with the wiring as I’m about to install these.
In Holley’s diagram, they include two ground wires - one as the main ground for the fuel pump, and the other as a ground for the fuel level sensor body. The instructions say to run the level sensor wire to the frame, and the fuel pump wire to the battery. Is there any reason that I couldn’t just tie these together and run them both to the battery (or the frame, for that matter?)
