If I wire this to my starter switch, would that make sense, instead of installing yet another switch?


For my two cents, I would put in the extra switch for two reasons. First being if you actually experience vapor lock when driving you will want to run the pump without the starter and two, a solenoid or other coil can have a huge inductive kickback or voltage spike when current to it is released. Depending on type of pump & where you wire it, the pump could be damaged.

If leaving it on concerns you, then a spring loaded toggle or pushbutton switch is the answer. Downside to either would be the need to hold it while driving should the need arise.
