My 77 Town Coupe had 2 as well. I never did figure out why either. Probably just something they added thinking it was a good idea.

Can I get some help here.I bought a GMC 1989 king

Next to the hose routing, there should be a VECI label -the Vehicle Emission Control Information label. If your particular vehicle had a smog pump, the label will definitely list it. As for other models, I don't Know, probable that back then some did and some didn't. California requirements were always stricter than other states.

What does the air pump on a 2001 Chevrolet impala do?

Air injection pumps or "smog pumps" as they are commonly called, are emissions devices used to clean up and aid in the burning of emissions such as carbon monoxide and hydrocarbons. These pumps inject clean air into the exhaust system to aid the catalytic converter in burning the excess emissions created at certain times of a vehicles operation.

I'm barely failing smog due to high hydrocarbons.

Hi Larry, I your position I believe I would take the vehicle for a diagnostic scan and then check the read outs. There could be a problem with any one of a number of sensors but I believe you'll end up with all odds pointing at the cat. Regards John

Where is the fuel pump on a 1990 dodge dakota

Fuel pump is in fuel tank,as in almost all vehicles for the last 30 years!!!
You can see the top of yours,looking above the frame rail, and across the top of tank
May want to remove bed bolts,except rear ones,and tip up bed.
Your not getting the tank straps off,too rusted,and no parts.

If your 84 mustang is fuel injected, it has a check engine light. If it is carbeurated (like mine) it does not. 85 and up are EFI, 84 was the crossover year.

No AIR pump

Your vehicle came with a smog pump. It may have seized up (probably breaking the fan belt) and my have simply been removed by a mechanic at an earlier time. It is located below the alternator on your vehicle.
If there is no pump but a bracket to hold it, it has definitely been removed. Vehicles will often pass a state smog test without the pump. It only works during engine decelleration (when you lift your foot off of the gas pedal)
