GM A body fuel line replacement?

[3X24SPD]

When I did the body off on my 66 GTO, the original fuel line running the length of the frame looked mint- so I decided to keep it.
After all was said & done, and the car was back together- getting ready to start the engine- no fuel.

I first tried blowing through the line with air. Then tried running a wire through. Then spinning the wire on a drill.
No dice- blocked. Damn. No way.

I'm not pulling the car back apart.

Bought the one-piece pre-bent line and replaced it.

If you have the car up high on a lift, it's not a bad job at all. Quick & easy.
As mentioned, the line comes bent in half to start- you just unbend and start sneaking it in front & rear.

You do have to bend the line slightly, and then bend it back after sneaking it in front and rear- but it wasn't too tough. And you can't tell it was ever bent if you're careful.
