rubber fuel lines with hsr

Okay I just installed the HSR and i had to do my own fuel lines. Holley said to use high pressure rubber fuel lines, but fuel pressure rubber hoses are rated to 45 psi. I will run probably like 50 psi though. DO they underate the fule lines. I will one day do all braided lines, but i have to order custom fittings to fit the lines from the fuel tank. I dont know if anyone is aware but the ones from the tank have like double flares. Any ideas would be great

My HSR has braided steel lines from the metal line inthe engine compartment to the fuel rail. I wouldn't use rubber fuel lines, its not worth setting your car on fire.

Working pressure 50 psi, max pressure 175 psi.

Braided for fuel injection would be the smart way to go.
