I recently purchased a PMO carb setup for my /6. My car has never used a fuel return hose since I purchased it many years ago. Do I really need to use the fuel return? My car is just for street driving. I am not really even sure what the fuel return is used for. I am trying to avoid using it because the fuel return lines in the tunnel have been removed by the previous owner and I really don’t want to install new ones.

I run a similar setup to 914Toy. /6 engine running Zeniths with no return line.
Facet fuel pump (9lbs-ish) followed by a non-bypass fuel regulator set to 4lbs. Make sure to install the insulating washers under the manifolds and you should be good to go. - Tony |

You can dead-head with a pump making correct pressure.
