Does anyone know the vacuum hose i would need to order from eeuroparts or fcpgroton to replace the cracked-up vacuum hoses (that start at the rear of the valve cover) on my original b21f? car is whistling a bit, figure it's the vacuum hoses somewhere, and it idles ever so little rough. want to just replace what needs to be replaced and narrow down the issues. slowly but surely i'll have this brick in order... had the timing belt and front seals done, coolant swap and valve cover gasket. suspension is next on the list!
