I've been running a Chinese fuel since July of 2017, with no problems cost $36.00 Au. The only difference discernable is the Chinese one is heaps quieter. There are definitely varying qualities with the Chinese pumps. There have been reports apparently of failure straight out of the box, but I have been unable to find any reports. So although I and others have experienced no problems to date choose wisely, grasshopper. I chose the supplier I went with as they are a manufacturer.
