Another noob question

[FordTempoFanatic]

Doing some exhaust work on my truck. Pipe broke just before the muffler. But as I work on that, I noticed a little rubber hose that runs to the catalytic converter. What is this, and is it important to replace/repair?

If that's what I think it is, it should go to the smog pump.. feeds air to the cat to help the burn process...

No rubber hose routes directly to any catalytic converter. Some vehicles use a steel tube, it connects to a nipple on the cat converter by way of a clamp.

Since you failed to mention what year/engine size your truck is, I cannot tell you which rubber hose you are refering to, but it's prolly part of the T/E = Thermactor Emission system.

T/E = smog pump.

Well my truck info is in my sig. 1990 F-150 with the fuel injected 351 Windsor.
