Would any one of you be so kind to answer me some questions about B18 FT engine because I am installing it in Renault 5. I dont know from where does the vacuum hose on EZ 210 K start and finish and what is its purpose. Next thing is about the number of wires on lambda sensor and fuel pump pressure. One more thing is about three vacuum nipples on left side of manifold ( where are they connected to ). Thanks a lot, guys!!
