I'll concentrate on finding and using the Nissan-correct specification O-ring sizes.

"I'll try to check the sizes I have in that Santech MT2571 kit and other HNBR O-rings I have already, not super sure I can read difference between a 2.00mm O-ring and a 2.43mm one."

I went online, and if I ...

The ones we have are the same as the ones you have.

OK, thanks for confirming that the line is the same as I already have (and cut down to size in 2017). I'll concentrate on finding and using the Nissan-correct specification O-ring sizes.

Please also check the "depth" of the cylindrical part of the 1998 discharge line that goes ...

I don't know the size of the o-ring off-hand. I always just matched them up in my Master kit. Autozine and Napa are suppliers of Santech, which is one of the big companies where I still do catalog stuff. The issue is that you can't go by my year, make, or model. Kind of have to match it up. The ...

I heard that the dust caps are a primary device to prevent gas from escaping from a schrader valve, and not a secondary device (the valve being the primary). Is that true?
