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?  |

What does having the regulator after the carbs do for the system?

QUOTE(NARP74 @ Dec 9 2022, 03:19 PM)  What does having the regulator after the carbs do for the system? Maintains desired pressure at the carbs and allows full fuel recirculation as close to the carb inlet as possible. This is how the stock D- and L-Jet do it (as well as most legacy EFI systems) but at a higher pressure of course. OEMs are moving to returnless systems for reduced hydrocarbon emissions and reduced complexity (my '08 Civic Si race car is returnless.) - GA |
