What is the trick to installing a new fuel line? Options

[Larmo63]

I've got one fuel line to install (carbs) and the engine is out. I had no luck getting the new line in further than 8 -12"

I can't imagine doing this with the engine in without bending the f*ck out of the new line....

I feel your pain, brother!!

Racer Chris's stainless lines are terrific, but can be a challenge if the engine is still in the car. Mine were doing the same thing as yours - get a foot or so in then stop dead. Here's what helped for me:

Remove the right rear wheel.
Unbolt the shifter's three bolts so you can pull it up and to the left a little.
Reach inside the tunnel and flatten out the metal tabs that secure the lines.
Lube up the rear grommet (if still there) with glycerin.
Start sliding the supply line, the one on the right, first. As it goes in, rotate it clockwise to keep the front end bend pointing downward as it advances. You may have to wiggle it a bit. You shouldn't have to force it at any point. If it hangs, back up and move forward, twisting a little as you go.
It helps to have an assistant spot the line from above, and apply a little bit of downward pressure when you can see it through the rear most access hole.
With luck, you'll hit the sweet spot and it'll move forward smoothly.
Lube up the front grommet as well.
You can pull the line forward from inside the cockpit to feed it through the grommet.
If you don't have, or trashed, the rear grommet, 914Rubber makes a nice slide in replacement.
Thankfully, the return line, the one on the left, is much easier to feed.

Good luck! Hope this helps!!
