Re: dual tanks with late model EFI?

I have about 20k miles on the dual tank setup in my 74. Used EFI tanks with the pumps in the tanks, the soft EFI rated fuel line to the high pressure valve, then to a corvette fuel filter regulator, then a single line up to my LS rails. I can switch tanks on the fly without even noticing.

The only issue I’m having now it that my newly installed Dakota digital RTX gauges don’t seem to like the fuel signal going through a switch so it doesn’t read correctly. Had no issues with the stock gauges. I track my mileage(~20mpg) so it’s not a huge deal right now but I need to figure it out.
