I was told that the injector return line that has a light gray braid with an orange stripe is silicone.
True or False.??.

MBZ No. 605-078-05-81 ( all of the web shots of this no. are of the dark gray /black braid return line)
Local MBZ Dealer says the no. above is the light gray line.
Doesn't know of it is silicone.
World Pac No. W0133-171-5390

The black braid oe line lasts me about a 18 months and then starts to leak.
I was told the supposed silicone line will last much longer before it leaks.
