pictured is the carb setup from when I took the engine out.
It was a single line feed but I want to put a return line back to the tank. Where would I T that in the plumbing?  |

You will need to change to a return-type fuel pressure regulator, otherwise pressure would be almost zero as it flowed right back into the tank (easiest path).
The return will be on the bypass side of the pressure regulator. Edit: something like this should work, mounted before the feed lines to the carbs: https://www.holley.com/products/fuel_system...rs/parts/12-887 Kinda curious: why? Worried about vapor lock? You're still going to have that last bit of feed to the carbs that will not be full flow, and that's the most-common locations for vapor lock. |
