If there are two different O rings I might try some experiments soaking the O rings in both types of ATF. What do these O rings cost?

Had a look at both FG1 and FG2 systems and I think there might be an error, but not sure as we would need to look at two actual vehicles to compare. Refer to images below. FG1 states it uses quick connector BG3F656A to join high pressure hose to pump. The O ring seal in there is part number 388898S. Now when I look at FG2 neither connector or O ring are listed separately, but not sure if that is the fact. If they are then the 388898S O ring would be the same, worth around $6 each.
How ever the high pressure hose is different between FG1 and FG2 (only talking 6 here). FG1 has two hoses one for NA and one for turbo. FG2 has one totally different hose for all 6 applications. Sorry but I don't know the exact differences are????
