Vacuum routing - Cars & Trucks

Your truck was shipped with a vacuum routing diagram printed on a sticker, which should be mounted somewhere in the engine compartment of your truck. It is important to use THAT vacuum routing diagram, as vacuum routing varies widely from truck to truck due to optional equipment and regional requirements.

All Isuzu vehicles in 1994 were shipped with a VACUUM ROUTING DIAGRAM sticker. permanentely affixed to the engine compartment of the vehicle. Vacuum routing varies from vehicle to vehicle because of variations in optional equipment, and the sticker shipped on the vehicle is essential, as there really is no "standard" vacuum routing.

It should go without saying that it is IMPOSSIBLE to answer your question without first knowing the YEAR, MAKE, and MODEL of your vehicle.

That being said, ALL VEHICLES since the 1980s have been shipped with a VACUUM ROUTING sticker, affixed within the engine compartment. The vacuum routing varies from vehicle to vehicle, based on optional equipment, and the sticker shipped with the vehicle is the ONLY ACCURATE WAY to determine proper routing of vacuum lines.
