?
This is the second gauge that I bought. The previous ones I don’t know how but all the liquid had come out through the back. I’m hoping it’s not the quality of it just bad luck. Other than that it works great like it

Loses accuracy
Became inaccurate after some time of use. Used to read perfectly now reads 27psi over. Checked fuel pump and regulator to be sure. The gauge reads 27psi when its disconnected from the fuel system.
