I can now cut and fit the braided stainless fuel lines. I transferred the mock up tubing measurements to the fuel line and cut them to fit. I am using a tubing cutter to get a good straight line on the braided line. The tubing cutter also compresses the steel braid filaments at the point of the cut and helps keep it from fraying. The Dremel tool also gives a good fray free cut to get the hose end on correctly.
I now have the fuel system completely plumbed up with the plastic mock up tubing. The stainless braided fuel line is expensive so I want to cut and fit the stuff only once. Hopefully everything fits the first time.
Now that I know where the fuel lines need to penetrate the rear firewall, I went ahead and drilled out the opening. With the fuel injection there is a supply line and a return line to the tank. I will plumb up the system with some cheap plastic tubing and then cut the braided stainless lines to match. This way I can do my best to not waste the expensive stainless line.
