Can you replace the hard lines off the fuel rail hard line with flexible lines?

So I bent my first hard line off the fuel rails hard line. And I have a deadline of a few weeeks to get my GTA going. Does anyone know if you can replace those 2 with a new flexible fuel line..
Here's some pics.
Or if someone has this line that I need and wants to sell it that would be great!
I only need the bottom one, not the pressure line, the one with the smaller opening.
Thanks guys

YOU CANT USE REGULAR FUEL HOSES. FUEL INJECTION IS TO MUCH PSI. YOU CAN TAKE IT TO A HOSE SHOP THEY CAN MAKE IT FOR YOU. I DID THAT WITH MY 84 GRAND NATIONAL. IT'S A HARDLINE WITH A FLEXABLE HOSE IN THE MIDDLE AND I COULDN'T FIND IT, THEY WERE THE ONLY ONES THAT COULD FIX IT.

No need to SHOUT
System is nominal 45psi operating pressure as set by reg, may spike to 70 psi

You need the correct adapters to fit the rail and other end and either run AN fittings and s/s braided line or use 250 psi injection hose with barb fittings (cheaper )

Metric O ring to -6AN Fuel rail adapter
( check size first , some cars have 14mm on return line)

AN Barb fitting for push on hose ( need box cutter to get hose off after fitting )

Hose ( many different brands ; just make sure it is rated to 250 psi )
