Last night, I finished putting together the dash (still a lumber of loose ends there, literally and figuratively), filled the crankcase with oil, and the radiator with antifreeze. I put a temporary fuel container under the hood, did my best to purge the lines, and tried firing it up. I couldn't get it to catch (definitely air in the fuel system still) so I'm going to complete the fuel system build before I try again. I plan on using the fuel pump in the tank as-is, but I found some
low pressure switches on the Mendelson's website, so I bought a couple, along with some other odds and ends. I hope the connections for the switches are a standard type; there isn't much info on the page. From experience, I know that trying to wire the pump from one switch is likely to cause a lot of cycling within a narrow range, so I designed this circuit:
The pump will run until the high pressure is reached, but not turn on again until it drops below the low pressure.
