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

I just did this with my car. The tunnel photos in this thread helped me.

I got a boroscope for Christmas.

Very cool. You can get the Android ones for $35 bucks.

There is a thread on them with the link.

I'll give it another try today with the right rear wheel off and I only have the one big line to install.

I watched the video, my experience wasn't anything close to how those went in.

Note, the pictures are very helpful but do not show the fuel pipes, which lie next to the passenger side of the tunnel.

But the music was very soothing....

The boroscope idea is great!

I have one. Thank you!

There are 2 access panels to look through. You really don't need a horoscope. The first time I did one, my teenage son helped me spot it down the tunnel with his cell phone flashlight. Took less than 10 minutes for both lines and I did not loosen or remove the shifter. WD-40 isn't lube. Use a real lube and it will slide easily. You might have to rotate it some as your spotter helps you sight it down the tunnel.

I used wire puller lube on the steel line and gromet. That worked well.

Engine was out when I did mine but rotation of fuel line was key. It got hung up, I removed and tried at a different angle and it went right in.

Bore scope has become a must have tool for the 914.

Yep, I just got a scope too for about $20 on Amazon....
Hooks up to the phone.

I'm using a boroscope, I watched the video, tried everything. No luck.

Rubber tip is now gone, at one point, I couldn't get it back out. Really frustrating. I got it quite a ways in, it seemed to go all the way to the original clips, but then wouldn't go any farther no matter what I did.

I wish I would have just kept the 10mm soft line in there, it was in perfect condition.

What is keeping it from moving forward? Has to be something. Are you using a helper?

Mine did exactly the same thing at one point. Really frustrating!

Just spit-balling here:

Which hole are you feeding it through? The 10mm line hole on the right or the 8mm hole on the left? Would it fit into the hole on the left? Since that one is closer to the centerline of the car, it's less likely to catch on the sidewall of the tunnel. My 10mm line was a pain to get installed, but the 8mm line seemed to go much easier. You said it was for a carb set-up, so it doesn't matter which hole in the rear firewall it's going through, since you're only running one line. (Although many support a return line for fuel circulation.)

If the holes are of different sizes...nevermind!

Other ideas: have your spotter topside watch as the line moves forward in the tunnel. When it gets stuck, back it up a little and have them push down on it with only a little bit of pressure. I know it feels like it's getting caught on a tiny edge when it stops.
It's the upwards angle of trying to get it in with the engine still in the car that introduces the challenge.

Good luck! Keep trying...don't give up.

I tried and tried with the right hole, then tried the left 8mm hole.

It went right in. Drrrrrrr..... (IMG:style_emoticons/default/beer3.gif)

I always thought the larger hole was easier then the smaller hole.......or was that what she thought..... (IMG:style_emoticons/default/confused24.gif)

[Larmo63]

The smaller hole was easier, and smelled better.

This is what I did and it literally took me about 10 minutes for both. I sat under the car with my feet towards the front of the car. I fed the lines into the hole and pushed. As I pushed the lines I twisted them left and right. Each line went into the tunnel and all the way forward to the access panel near the pedals. Every time it seemed as if they were held up I twisted some more and they eventually worked their way forward.
