The filling with the oil worked perfectly, only the teaching of the pump parts afterwards until the next use is a bit cumbersome. This is certainly easier in a workshop where the pump is used more frequently.
Product goes like this, suction hose too long, touches the floor too soon when screwed in. Pressure hose too short, because it is difficult to pump in the engine compartment, you need a longer and more flexible hose. Even if the price is not particularly high, this pump is not an asset. Next time it would be better to use a longer hose and funnel.
