I like to have a port that I can screw a small fuel pressure rated gauge into for testing to help make sure your pump, fuel plumbing and regulator can keep up at full load.

Is fuel being pushed into the gauge Andy?

That system is a dead headed system. The gauge is at the engine end of the line.

It's glycerin that you can see behind th egauge glass,to dampen the needle movements,not fuel.
