Need help with part ID-Ford van
I'd appreciate help identifying a part on my 1995 ford van, 5.8 engine.
It is a hose that seems to run from the exhaust manifold up to the engine air cleaner intake tube.
It is not shown in the diagram for the 5.8 engine in the shop manual. But a similar hose is shown in the diagram for the 7.5L engine. There it is called the secondary air injection silencer inlet hose-but I'm not sure this is the same part.
When running, the hose seems to inject air into the air cleaner intake tube. Not sure where the air comes from...or if it is exhaust though that would seem strange.
Thinking of fashioning a cold air intake that is less restricted than the current version.
Many thanks
Tom
