85 380sl and 92 300e 2.6l
85 380sl low side a/c hose

can someone please tell what the other 2 hoses that are connected to the low side pressure hose are for?
thank you, in advance!!

Thank you for your quick reply! But, I'm still a bit confused. As I understand the lowside pressure line is a compressed low pressure gas-freon, in that line.

Now, fuel is being cooled in the a/c system? or is the fuel just passing through that line. and how is the fuel being cooled if the a/c is not charged.

so, is fuel going through the two fuel cooling hoses going in the same direction going where? and coming from where? ahgggg.....confused!!
want to learn so much about my car!!! been trying to learn have tried manual but nothing and google come up with nothing!!!

I tried looking up that lowside a/c pressure hose, but all the hoses they sell don't have the connections for the fuel cooling.

and how is the fuel cooled? through pressure? and why does the fuel need to be cooled?

Not sure if I'm asking the right way, but if someone could please take a moment to explain???

thank you again myway for your quick response and pictures!!!

450SL

The ones that connect in the picture (one missing)? If so they are fuel cooling on the return line.
