I use it to draw oil from tanks and connect it to a 12Volt battery (WARNING DOES NOT WORK WITH 24VOLT POWER, IT BURNS) it is very fast it pulls at least, 40-50 liters in 2-3 minutes, and generally it is trustworthy and very fast for these fuels, it also has a sieve that acts as a filter for the liquid it essentially absorbs so that no piece (whatever) passes through and causes damage, either to the pump or generally to keep the liquid clean. I recommend it without reservation, it's worth 100% of its money, it eats a lot of wood and doesn't make a sound, it's worth the effort
