Hey guys, I'm new here.
Crossfire 2004
I'm having problems with my fuel system or to be more exact, the thing in front of the fuel filter/pump system (see picture) has started to leak due to old age, rust or something else.
After doing some googling I get two results, it's either called a "one way check valve" or a "Diaphragm" and as far as I know they're things that dont do the same thing.
It looks like it has been discontinued and I can't find any replacement part.
Dose anybody know where I can buy a nother one or something similar, maybe something Benz used to use?

Pre thanks
