I’m trying to find replacements for the hoses coming off the smog pump including the one going to the air cleaner. It looks like they are no longer available from Toyota. They appear to be 7/8” and 1” hoses (I think). Has anyone had any luck finding correct application replacements?
Does anyone know the difference between a 1977 smog pump and a 1979 pump?
Looking at the pictures it appears the casings are the same with the exception of the piece circled in red. I was wondering if a 1979 smog pump can be used in place of a 1977 without hindering or altering functionality...
What type of hose should be used between EGR valve and carb(see yellow cap below)? Vacuum, fuel, etc. It appears to be around 5/8 diameter.
Vehicle is 5/1977 FJ40. Original hose appears to be NLA.
