"Explain to me what I am looking at there???"
I made hose jumpers to run from the fuel filter into the fuel head and the return from the head back to the return on the car. I ran 12v into the engine wire harness from the car connector to supply the 12v to the WUR and a ground between the engine and the car. I also used a remote switch to energize the fuel pumps while standing at the engine. I set up the control pressures on the Leask adjustable WUR and balanced the injector flows this way, it's so much easier than with the engine in the car.
