The below image is inside my 1993 F150 4x4 351WThe item has what looks like a vacuum port on the bottom the orange looking object in for ground is actually a white plastic vacuum hose that goes to than item. It comes out of the harness with two others that go to emissions canister ( The coffee can looking one ) it got melted off with the header pipe you can see. It melted itself closed so there is no leak fficeffice" /><O></O>
What is it, and used for what? Is it important to get reconnected? <O></O>
Thanks in advanceJ<O></O>
BTW it passed inspection so another F150 back on the road. Been sitting in my garage for 7 years over 7 years it acquired 20 miles since last inspection.

That's part of the Thermactor air injection system, you'll probably get a code with that vacuum line disconnected but it's not anything that will affect engine operation as long as there are no vacuum leaks.

 

Thanks

No codes showing on the OBD-I Scanner and no Light on dash, Must be sealed good. Would you know the part name, Would like to get it replaced and can not find a diagram on line anywhere that refers to the part, lots of explainations on the system it'self but no parts or diagrams with that specific item

 

Fixed now to just keep the header heat away from it

Thanks again
