Default Re: using the stock mechanical fuel pump with electric

I do that for the roadster's 59A. Electric pump at the tank in the trunk for priming before startup, and backup. Plumbed from the tank with a shutoff valve, to a filter, through the pump to the mechanical fuel pump on the engine. The 12V Facet fuel pump I use is model #40163 which is self regulating with a pressure range from 1.5-2.5 PSI. These are manufactured in the USA by Purolater in Elmira NY. Available from Aircraft & Spruce, $50. They don't make a 6V model.
