Does anyone know if the 1996 5.8 F250 has the second evap canister purge solenoid? t's part c171. I have c170 on there, and my mechanic said that there should be two but the second one appears to be missing--at any rate he can't find it. The light is on and I can't get my car smogged. Is my truck even supposed to have that part?

 

As far as I remember they only have one solenoid. If I'm wrong, hopefully someone will correct me.
