What filter is this?

There is an upright canister filter below the air intake tube, behind the radiator on my 3.6. Fuel? Transmission?

Oil filter, when you change the filter be SURE to only tighten to 18 ft. lbs, just a bit tighter than hand tight.

Oil filter is a cartridge under the black cap. This is a true screw on canister type.

If you mean the one hanging in air just behind the radiator fan see below:

On vehicles equipped with some engines there is an electric vacuum pump located in front of the engine. The vacuum pump has one electrical connector on a pigtail, a vacuum hose with a quick-connect type end, and a vent hose. The vacuum pump mounts with two rubber insulated studs to reduce vibration.

The Electric Vacuum Pump (EVP) system is installed to provide supplemental vacuum to the brake booster when the engine vacuum supply is low. The vacuum pump is connected to the engine and the brake booster through a series of hoses and one-way flow check valves. A vacuum pressure sensor, mounted in the brake booster, provides information to the Anti-Lock Brake System (ABS) module, then the vacuum level is sent over Controller Area Network (CAN) to the Powertrain Control Module (PCM). The PCM modulates the EVP operation to maintain the brake booster vacuum within a given range. This system ensures that the customer experiences a consistent brake pedal feel under all driving conditions.

A two wire electrical connector is used to supply power and ground for the vacuum pump. Operating voltage is between 9 volts - 16 volts. Control of the vacuum pump is provided by the PCM using a low side driver to a normally open relay (coil side). The relay coil side power is from a fuse in the under hood Power Distribution Center (PDC). The switched power circuit to the vacuum pump relay is wired directly from the battery through an in-line fuse holder located below the remote battery post connection on the RH side in the engine compartment. The relay is located on the LH shock tower in the engine compartment.

The ABS module monitors the vacuum pressure sensor and when the signal indicates low engine vacuum the PCM will cycle the vacuum pump as necessary to add vacuum to the power brake booster. The vacuum hoses are connected between the vacuum pump, the engine manifold, for Manifold Absolute Pressure (MAP) sensor signal, and the vacuum pressure sensor (on the brake booster). When the PCM cycles the vacuum pump on, the PCM monitors the MAP sensor and if the vacuum signal does not indicate a rising vacuum then DTCs will be set. Additionally, the ABS module monitors the vacuum at the vacuum pressure sensor and DTCs will also set in the ABS module.
