Vacumm hose diagram

did you try auto zone libaray

We do not have these diagrams. Try the public library is my best suggestion or try and find a used factory manual.

the dealership can give you a schematics print out

this could be several things causing this code,first make sure gas cap has been turned till clicks every time u fill up,could be bad gas cap,then follow fuel lines from the tank under car to the evap box,checking hoses for cracks or need replaced,then if none follow the lines again to motor,most of the time this is also some small lines vacumm hoses that need replaced going to the evap canister,but check vacumm hoses dealing with the evap system,just went through this for my mom on her van and it was two small 5/16 hoses hidden under the air filter box,you could also pay a shop to doo a smoke test on car,could be costly,would try myself first,hope this helps you,it did me and saved a bundle

You haven't provided make or model!!
Either way all car manufacturers are req. to place the diagram in the engine compartment, check under hood, or rad cover, its there somewhere........
Hope this helps

go to autozone.com put in your make and model if they dont have one try going to the store and buying the book for your model the book only cost around 11.00$ and i know this will have the diagram in it

check your fuel filter. and your pump. be sure to give the carb a good bath with crab cleaner to rule out clogged hoses or plugs

Check for vacum hoses that are rotted or broken!

Only place to get that is from the dealer or go on line to alldatadiy.com and buy a one year subscription for your car and it will have the locations on everything on the car, you might get the dealer to give you a printout for it as well, they may or may not charge you for the service.

give this website a try to see if they have your car listed it www.autozone.com if they do not stop at a local toyota dealer in the part department and i am sure they would print you out a diagram for your truck
