I installed the gauge today, and everything went ok. Except I had to fight annoying leaks all day. I tried to get the air out the best I could. How do you bleed these gauge's the proper way? Also I've got 16-17 psi at idle, is this good? Thanks
There is no need to bleed the air out of the diesel line to a fuel pressure gauge (or its isolator, if used). The trapped air has the same pressure as the fuel. The gauge does not care. In fact the compressibility of the air reduces some of the shock to the gauge movement.
I have the comp box on mine and on 5*5 it will not drop below 12 at wot. I used the isolator and you only need to bleed out the isolator not the line. Search my posts if you want to see some of the install and pics and info.
