Fuel systems for drag cars

My 250 mallory cost me $50, reman, at a supershops warehouse sale. (If that tells you how old it is. I think the original supershops closed in the nineties).
I try to use hard line as much as I can. My aluminum lines haven't ever leaked, last 30 years, and probably cost a tenth of what the same length of braided line would be.
I think I had $300 in the nine second cars fuel system. I bet it would cost $1500 to duplicate it today. (The mallory pump is over $600 now).
