Diesel prices are through the roof (2.3€/L) but my backup fuel storage is ripe for rotation. Hopefully the prices have gone down a bit once I finish the last canister.

I always struggled with these 30L canisters and only strained my back and made a mess trying to pour it manually. This 14€ pump sure makes thing easier.

    This! I was talking about fuel pumps with somebody yesterday. There seems to be two methods of pumps:

    • simple rotary blade, most common. cheap and can be fast. but it cannot create a pressure difference, so if you try to create a vacuum in a room with it, that won’t work.
    • compressor pump. it does not use a rotary blade, instead it uses a cylinder that repeatedly fills with input from the side, then a mechanical piston moves inside that compresses the (gaseous) input, then a valve opens on the other side to let the gas out. it is now compressed and at a higher pressure level. this can be used to create a vacuum and to pump gases against a pressure difference.

      This has the motor inside the piece visible in the picture but the propeller is all the way down at the end of the shaft that I stick inside the canister, so it doesn’t need to suck air and thus doesn’t need priming. I bet a basic drill pump would work just fine as well despite most of them not being rated for fuel.
