from memory there are two hoses coming off the "boost soleiniod"
about an inch down from the soleiniod on one of the hoses was a yellow band of paint (0.5cm thick),
i squeezed it and could feel something solid was in there,
took me 5mins and i am no good with cars
It dose seem to make a VERY loud rush of air sound at boost.
dont know how normal that is
I will take it to cruz this week and get some more advice
that is if no one knows what i mean about the sound
