Vapor Canister Question
 
1 Attachment(s)
1994 C1500 5.7L AT. Noticed a rat chewed the purge fitting off the vapor canister. Anyone know if the top can be replaced on this, or any way to repair it?

Iíve never seen just a top replacement. Maybe you can grind it so the fitting is straight up, versus 90 degrees, and then possibly clamp the hose to it.

Or pay like $80 for a new one.

Yeah, I've seen the prices . . . damn. Guess it's time to bring out the Yankee ingenuity.

It's required for emissions. It collects fuel vapors and then peridocally releases them into the injection system to get burned instead of having them evaporate in the atmosphere.

You could technically vent the tank to the air but you'll have a fuel smell and depending on where you live, won't pass emissions inspection.

In my 94 I by passed it all together. Just connected the two lines together and whent stait to the tbi. Never had a issue. Only reason I did this was to fit the under hood tool box the 95 ups got.

It stores fuel vapor to be burned later, so to really sell it you need to mention that it increases your fuel mileage a tiny bit.
