I have only bought the replacement hose set for 15.90 euros, to have a probe for my oil pump with which I can suck the oil over the Ölmessstutzen the car. The set consists of 3 flexible tubes of various diameters similar to those used as a probe at Aral petrol stations. Two of them, the probes, have inside a thin metal rod, so that the tube remains as straight as possible. Super quality - also works with hot engine oil without the probe being damaged. I write that, because before the purchase had given contrary information and in my (non-Pela) Ölabsaug electric pump in the manual is smooth max. 60 ° C (a laugh when you drive the car warm to generate low-viscosity oil). From the quality of the probes, I can imagine that those who rave about the Pela pumps in the car forum do not do this unfounded.
