Dumb Question...Electric Water Pump Newbie - 12/18/22 06:14 PM
I'm doing a "leak check" on my first R3/W8 build. Using a short deck Arrow timing cover, and a Meziere pump. I am also using external water input through the center freeze plugs. This is my first electric water pump build.
This pump is used although I was told it is a low hour unit when I got it nearly 5 years ago.
I began by pre-filling the engine through the upper hose, and filling a wash-tub. It should be noted that this water reservoir is about 1 foot lower than the water pump itself.
I placed the lower hose into the tub and tied the upper hose in a fashion that would allow it to discharge back into the wash tub.
I connected the pump to a Snap-On large jump pak as a power source. I cannot pick up a prime with the pump. I can hear the pump running, and a few times it sounded like it was "catching a prime" due to a change in tone, though that was only momentary.
Am I wrong thinking the pump should be able to pull the water from the tub, or do these pumps require an elevated/closed loop to allow the weight of water to aide its function?
I have verified block filling by pulling the lower drain plugs in the block.
