A/C Liquid Line Question

Alright so I wanted to ask a quick question about the liquid line running under the passenger battery tray.

Preface to why I'm doing this, my condenser had a pinhole leak from a puncture and I lost pressure obviously from that.
Prior to this, the A/C blew cold, everything worked as it should.

I ordered a new condenser as well as a new accumulator/drier as when/if the system is exposed to atmosphere, it's good practice.

I've also read about the liquid line replacement in this scenario as well, but it mainly seems that this is replaced if a compressor grenades or there is a blockage to the system. I have no such issues and it was working fine before all this.

Am I ok to stay with the current line that's in there or do I need to replace? Can you remove it without taking the battery and tray out or is this a necessary thing to do to get er out?

I've done A/C work on the TDI and other trucks, so I'll be fine drawing a vac, adding the oil, as well as refrigerant spec by weight.
Thanks in advance!

No need to replace the liquid line under the Battery.
The orifice line is the one recommended to replace if there are any cooling issues.
I know on the earlier 3rd Gens the orifice was smaller than the later ones.
I replaced mine a couple years back and it was a noticeable improvement in the A/C.

New orifice line, its cheap insurance. Take the line with you if you go to the dealer. They ordered the wrong one and the right part # wasn't even listed.

So I wasn't having any cooling issues, my A/C was ice cold before.
Is there any reason to replace that line if it was working great before?
Is it required to remove the battery and tray to replace it?

Isn't the orifice tube part of the liquid line? I believe this is the correct one...

Can anyone confirm if this is the correct part?
Trying to get everything ready ahead of hand. Can't really crawl around on/in the truck as I dislocated my wrist and am currently 1 handed...

You will need 2 hands to seperate those connectors.

Haha yeah I figured. I enlisted my buddy to help me with some of the things I need 2 hands for. He's got the same truck as me so should go smoothly (knocks on wood)

Thanks for the confirmation

no need to replace a line that isnt damaged, new orafice tube and accum are good insurance even if every thing worked well.

The orifice tube is part of the liquid line so you can't just replace the tube, you have to replace the entire line.
I'm replacing the accumulator. The liquid line was not damaged, no debris has been sent down it.
I don't want to spend the extra coin on it if it will function fine.
Your statement is kind of contradicting, no need to replace the line if it's good, but it's good insurance to replace it...so it is or isn't necessary?
I can put that money towards another project if it's ok to leave as is
