The ZL1 pump looks so good! That would be very appropriate for my build as well. I like what William posted. The 90* fitting with the pump clocked a little may work in your application. I made my own line, which still took me three tries with the engine out of the car. As you can see, mine snakes around the lower radiator hose
I have seen photos of motion cars that used the factory hard line from the fuel pump connected to a generic chromed holley dual feed line with a rubber hose. I used a copper oil pressure line for my fuel pressure gauge because I felt it looked the period.
FWIW I believe NHRA does allow a mechanical fuel pressure gauge in the cabin if it is a steel braided hose, I've seen drag cars this way
