My 51 Plymouth is like that. Runs just fine, can set for weeks on end and fire right up. I don't use any special fuels or anything. Whatever pump swill is at the local Shell.

The interesting thing about this setup is that the factory flathead induction system sit right atop the factory exhaust manifold, the runners are nestled together as well. No phenolic spacer, no clothespins, no heat shields or anything. Mechanical pump.

I don't have fuel percolation or vapor lock issues. Others with similar setups do. I dunno why, unless that "contains up to 10% ethanol" is really E0. We do have one station in town that sells ethanol free gas, but I don't need to pay the vig for that as I don't have an issue.
