Kaiser Forum / running an electric fuel pump
« on: February 07, 2024, 11:33:06 AM »
Hi all,
We here in Canada have just been dealt a blow: ethanol is now allowed in all levels of gas. Until a few months ago, premium gas didn't have ethanol, so we had fewer vapour lock worries than drivers in the US. (It's also generally colder here, so that helps, too!)
My '53 Manhattan has the regular mechanical pump and a switched electric fuel pump. Am I better to run the electric pump all the time, or only in times of sputtering? The car does seem happier when I run the electric pump full time, but will that keep vapour lock at bay?
