darkzebra Posted October 4, 2009 Share Posted October 4, 2009 I bought my 82 280ZXT with no purge canister, and the line from the tank "blocked" upfront. I have since bought a used canister for a Geo Prism (very flat) to install. On top of the Prism canister are 2 ports labelled "tank" and "purge". At the bottom is another port with no label. I am presuming the "purge" and the unlabelled port would be connected to the intake manifold and the accordion hose after the AFM. Is this correct? Is there a specific order for them to be connected?

oldschool2 Posted October 5, 2009 Share Posted October 5, 2009 See my post titled: 280ZX Fuel Tank Vacuum and Fuel Check Valve (last two posts). Currently on page three of these S130 Series posts. The Tank fitting is for the Fuel Tank Vapor to feed into the charcoal canister. The picture on my noted post shows a modified set-up. The round object to the right of the picture is actually a check valve that normally is under the car near the fuel pump (on a non-turbo). Note the larger hose. It is from the fuel tank. Basically I just inserted the check valve between the fuel tank VAPOR hose and the canister (relocated it) from under the car to the engine compartment. Blocking the fuel vapor hose will cause extreme pressure build-up in your fuel tank in hot weather. Maybe it has been modified at some other point leading from the fuel tank. Probably a good ideal to trace the hose back to see if it feeds into the fuel tank. Quote Link to comment Share on other sites More sharing options...
