Robert Finley's Journal

Installed carburetor overflow lines, which had long been missing. This resulted in a safety condition because the carburetor float blows would dump gas on top of the exhaust manifold if they overflowed.

I evaluated two different repairs before choosing the overflow lines. I read where the overflows have been routed to the adsorption canisters. That may be a good idea, but the thought of dumping raw gas at 2-3 psi into the canisters if an overflow occurred did not sit well with me. I thought it safer to dump the gas on the ground if it became necessary.

I believe that the OEM method of running these lines had them fixed to the left side engine mount, but I could not figure out how to do that neatly. I ended up attaching a bracket to one of the bolts that holds the fuel pump blanking plate and that worked pretty well. The lines themselves are 1/4"soft copper that is routinely used in refrigeration systems. Less than $10 at home depot.
