i have a mechanical Carter, has worked fine, but sometimes, when they put out the winter gas, with the higher volitility rating, i wonder if i were to run an additionial electric pump, if it would help.

To that end, i wonder if an electric pump has to run, or would it be a restriction to the engine mounted mechanical pump? I just can't figure out the complexities of an electric before the mechanical.
