SC hard fuel injection lines - firing order Q

[mr.bch]

While pulling and cleaning my 81 SC injectors last night, I noticed the metal tubing of an injector line was almost worn through by contact on the metal edge of the blower housing. Yikes!

So I want to replace it with one from our host's catalogue. However which cylinder is this? Firing sequence is 1-6-2-4-3-5, right? My cylinder line that was rubbing was the farthest forward, driver's side line. Is this #1? Anyone order the lines that I am about to? Are they all precut, flared and bent, so I just buy and install?

And lastly, anything else I should be cleaning or R&R'ing while I am in there? I am going to keep and clean my injectors and replace the injector O-rings. Should I replace the little injector sleeve O-rings or just drop in new injector sleeves (do the sleeves come with 2x O-rings?). One of the sleeves came out when I pulled on the line so I am thinking replace it all. But that is just me guessing.

The cylinder order, if you're looking from the back of the car towards the front of the car, the cylinder order looks like this:

3 6
2 5
1 4

So, the cylinder closest to the front of the car on the driver's side is #3.

I can't answer your injector questions, as I have no experience with that.

Firing order goes:

3 - 6
2 - 5
1 - 4

when facing the engine from the rear bumper. Closest one on your left is #1. Closest one on your right is #4.

The one you described is #3.
