Dual Tanks/Fuel Line Size Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

52Chevy4Me · 01-01-2022, 05:30 PM

First time poster, but have been getting a lot of great information from the forum for a long time.

I'm adding dual tanks on my '85 K20 build. I'm trying to stay true to factory by keeping the fuel return line as 1/4", yet all the aftermarket selector valves that I have looked at are 5/16" return. Were factory selector valves built for 1/4" return lines?

Any help on how to plumb it is greatly appreciated.

I'd have to look at my 85 k20. But it's in winter hibernation.
