Poor quality

First off let me say speedway service is great . This particular item (fuel pressure regulator) is poor quality. The first one installed leaked, speedway sent another one under warranty,and the second one only will only adjust to a max pressure of 4.5 psi This regular is rated to 14 psi. I will purchase another brand.

The fuel pressure regulator solved a problem that was caused by an electric fuel pump that was putting out pressure that was above the claimed specs. Crisis solved quickly!
