I recently got the A/C working in my 92 EX. The system was completely removed, flushed and many components replaced (drier, compressor, condenser, expansion valve all o-rings). I used synthetic ester oil w/dye and even R12 refrigerant (yes I have a 608 universal and 609 MVAC cert).
I left only two lines on the car which I flushed successfully still yet. They are the two that run from around the passenger side headlight / battery tray area to the evaporator behind the glove box. The reason being is this car has ABS which makes them more difficult to remove.
Anyhow, the A/C was working great but I've found a leak in one of the lines running to the evaporator. No big deal, I have recovered about 20oz of R12 and just need to order the line and another 12oz can of R12. However the line in the diagram from Honda doesn't look the same. P/N: 80343-SM4-A91. It's showing a threaded fitting running parallel with the line. Which is not the case. I've never seen one like that EVER and I've done this before. Their description puts the fitting under the battery tray when in reality it's behind the bumper running parallel with the radiator, rad support, condenser etc. Unless of course I'm missing something or there is a design I'm unaware of. I've done Hadsys systems and Denso. The connection is always behind the bumper.

The line I need is listed as # 16 in the diagram.
The discrepancy lies with where #16 connects to #15.
#15 runs from the pressure switch behind the driver side head light through the radiator support, across the condenser where in reality it has a fitting near the passenger side bumper light and horn. That is where it connects to #16.
What they display in the diagram is #15 runs back through the radiator support (90*) on the passenger side and has the fitting by the battery tray. Which I've never seen before. Anytime you remove the bumper you can see the fitting where #15 (coming from the pressure switch by the drivers side headlight) connects to #16 (which runs to the evaporator).
There is also a discrepancy between part number 80342-SM4-A19 as opposed to 80342-SM1-A19 listed for the same part. Which is #16 which is the line I need.
There is a $35 difference between 80342-SM4-A19 and 80342-SM1-A19. Part #16. The line I need. Which leads me to believe there might be more of a difference than just who manufactures the line.
Again, google search a CB7 with the bumper off. You can see the fitting between #15 and #16 right by the passenger side horn. Not at all where the Honda diagram has it.
I would purchase the line anyhow. Diagrams are sometimes wrong. However there are two different lines listed for #16 and very different pricing and no explanation as to why. And compiled with a possibly incorrect diagram. So that's why I'm stuck.
Long read I know. I've been trying to figure this out. Anyone who can shed any light on this would be very helpful! Thanks!
