2 out of 3 worked fine
I bought 3 of these and 1 failed after about 30 minutes.
I did receive a replacement, but still waiting to get reimbursed for the bad one.

Quality is not suitable for engines. Cheap plastic
We used this in a diesel engine fuel flow application and the connectors were sheared off as soon it was installed. The plastic is weak and cannot be used in a normal fuel line. We tried 3 and they all broke. We tried to get service to refund or find a way to help us but although we got an initial response there was no follow up and we had no resolution. We ended up getting a flow meter from an aviation company. The metal components were much better and have been working very well.
This was expensive trial and error. An unfortunate disappoint experience for us.
