Electric pump = flooding and/or fire hazard, unless you wire it through a switch that senses oil pressure and shuts it off if the engine stalls. There is a combination oil pressure warning light and fuel pump switch that's used on fuel injected GM engines that's an easy way to accomplish that. Mechanical fuel pumps have been working well since Henry Ford put one on the 1932 Model B flathead V8- - - -why mess with success?
