Air Pipes to Catalytic Converter Question-Photo added
Update--question reposted here on 1 Jan--
For the 1991 E350 rig in the sig.
Question is which of the two air intakes to the catalytic converter comes from which two pipes up by the engine?
At the catalytic converter, there are two intakes:
A. on top in the middle, a blue hose onto a metal pipe then going forward to under the dog house passenger side
B. at the front of the converter, a metal pipe going forward to under the dog house passenger side.
These two metal pipes cross over each other on the way forward. They both seem to have fittings on the front ends for rubber hoses that would connect up to the two metal pipes coming down
Now up front under the dog house, passenger side there are two metal pipes strapped together with metal spacers (whatever called)that go down and (perhaps?) join up with the two metal pipes from the catalytic converter.
A. one goes up and gets a fatter rubber hose that curves over to the left and down into something in the middle (air pump?)
B. one goes straight forward lower down along above the passenger side engine top and into something or other farther forward.
I want to know which of these metal pipes up by the engine connect to which pipes that go into the catalytic converter
(There might be a part of some kind between these two sets of pipes, don't know)
Thanks.
