Manual Petrol Pump

[remembrance1]

Hi,

Im wondering if there are mechanical manual hand pumps for a petrol pump? If so, could someone explain to me how do they work?

Hand turns a crank that spins the pump

you must get smarter than the software you're using.

Answer to manual hand pumps:

How they work: by forcing air (at first) then fuel out of a contained volume, the pressure in the contained volume decreases, allowing external air pressure to push more fuel into the contained volume. Some use a piston and check valves, others pinch a piece of tubing with rollers in a sequential peristaltic action, some use a vacuum bulb with check valves. Pretty much any mechanism that can take a volume of fluid and move it to another place will work.

Go to a Fleet Farm type of store and buy one. Or talk to a contractor in your area.
