Fuel primer pump
At the weekly cruisin, a 64 plymouth guy , hemi, 2 fours described a problem a lot of us have of no fuel in carb after sitiing for 3 or 4 days. Takes excessive cranking to start. Did not matter what carb it was as we run quads, edelbrocks and holleys. So the hemi guy suggested using an electirc primer pump at the tank with a momentary switch before cranking engine.
I used an airtex solenoid pump near the tank -----tank, filter, solenoid pump, mechanical pump, filter, carb. The solenoid pump only works with key on and depressing the momentary switch . I can hear it pump then slows when pressured. I do know the mechanical will pull thru the solenoid pump -- test drove. Other than catching gas in a jar at carb I will wait 4 or 5 days to see if the solenoid pump will push thru the mechanical pump. Has anyone tried this?

Re: Fuel primer pump
Just to let you know my test results, this works. I waited a week to test which is plenty long to dry up the carb from past experience. I turned the key on, held the solenoid pump momentary switch until the pump changed tone --about 15 seconds, then set choke twice and started the truck. It will push fuel thru the mechanical pump with no problems. I plan on doing the same on the 442 now.
