Hi guys. I have engine converted to 6.0ltr LS L98 engine.
The hummer has a “in tank” fuel pump and regulator with the return line looping back to the tank at the fuel tank so because of this setup as factory I only have one fuel line from tank to engine.
I bought a universal fuel regulator I want to install in the engine bay but not to regulate the pressure but just to have a visual of what pressure I’m getting at the injectors.
Therefore, can I block off the return port on the universal regulator and just rig it up to fuel in /fuel out so it acts as just a pressure gauge ?
