EVAP Canister Lines

Hi all,

Does anyone know if/where they sell the line from the canister to the tank, and the one that goes from the canister to the metal line down under the fuel tank on the chassis?

Or perhaps know what size/type, inner/outer diameter lines and I could cut my own to length?

Thanks

Do you need just the hoses from the tank to the canister, or also the pressure control valve, in-line tee, and elbow from the pressure control valve to the tee?

I have the stock 94 fuel sending assembly, and the stock 94 canister in my old parts pile. I could measure those connecting pipe diameters if that would help. Could also measure the diameter of the purge connection on the canister.

The purge tube that goes down to the metal line, and the Tank tube that goes to the tank. It has that in-line valve, which I have. I ordered that and the canister from summit racing, just need to replace tank and purge tube. The fresh air tube stops just behind rear panel.

Re: EVAP Canister Lines

If no one has actual measurements/part #’s, measure the outside diameter of the metal and plastic pipes that the hoses slip on to. That gives you the inside diameter of the hose. A little bit “tight” is OK. The hose should be vacuum rated, and suitable for exposure to fuel, which provides adequate thickness/outside diameter to resist collapse under vacuum.

There is a free download of the 82-02 exploded parts manual in this link. Might provide part numbers.
