I use my mechanical pump and prime my system with my Airtex using a long handled toggle switch with an LED in it that lights when "on" .... most the auto dealers here carry them. I turn on the toggle and slowly count to "5" before pushing the start button. If I get a vapor lock situation in hot weather, I just leave the toggle/Airtex on until the mechanical pump, line to carb, and engine compartment cool down allowing the system to work normal. (Better than having to hold a momentary switch in.)
