I got the excellent set of pre-bent stainless steel fuel lines from Racer Chris some time ago, and got around to installing them. My car is a '70.
I can get the thicker line about halfway in (approximately) before it seems to hang up on something. I can rotate the line a few degrees and push a little, but it seems to be catching on something. The engine is still in the car.
Is there a trick to how to wiggle it? The rear firewall grommet is toast, so it's not a question of lube.
There used to be a YouTube video of one of our users installing his line, but I get a "You can't play this video in your country" or similar error message. (I am in the US, along with the original video poster, btw.)
Suggestions welcome.
