The thing which used before was broken and was searching for replacement. Of course I can use it without problems. I think that other machines are planning to change the switching specifications, so I think that I will order again.
It is used for switching of the petroleum fuel tank of the pleasure boat

I was not concerned about it because it is a product of a leading manufacturer. It is installed as for switching the light oil tank, I think that I am going to use the degree of durability, although it is not a part where pressure is applied so much.
Failure of the machine about 40 years ago Due to the fact that the same type of parts can not be found, we purchased this product and the repair was completed. Because the direction of suction and exhaust are different, piping with elbow etc. is done again and the machine is running to ten.
