Fuel line replacement on my '69

[TWINRAY]

I know it cannot be done with body on frame and body off is the way to go but I'm doing body mounts, the one side at a time way, so in the process could I raise the passenger side enough to get the lines on without cutting them? I've done the brake lines without too much cursing. Doing the lines makes the Trailing Arm job look like a snap.

I have already bought the pre-bent lines and cannot return them cause it's after 30 days. I know they will have to probably be (slightly) unbent and then rebent again in this installation process.
