Looking for some help on a Nissan Sentra 1991 with a engine number starting with e13s.... Need to connect the vacuum pipes back on. Can't seem to find the correct vacuum diagram to help out. Basicly need to know where the pipe connects to from the distributor to where ect.

From the looks of it, the only 1.3 B13 sentras come from the Philippines. Unless I am mistaken, you may have better luck talking to the dealers in your country. Otherwise, try the vacuum diagram for a GA16de. It is the fuel injected 1.6 version of your engine that was used in the states. They are the same engine family so maybe they will be similar.
