Symptoms of a Clogged AY500MT002 Filter‌

Replace immediately if experiencing:

Loss of Power‌: Restricted fuel flow causes sluggish acceleration.
Engine Stalling‌: Fuel starvation due to blocked media.
Excessive Smoke‌: Incomplete combustion from contaminants.
Check Engine Light‌: Codes P0087 (low fuel pressure) or P0090 (sensor circuit).
Water Contamination‌: Milky fuel or separator sensor alerts.
Installation Guide‌

Tools Needed‌: Filter wrench, drain pan, Teflon tape, safety gloves.

Depressurize System‌:
Locate the fuel rail Schrader valve (diesel engines) to release pressure.
Remove AY500MT002‌:
Unscrew the old filter and drain residual fuel into a pan.
Prepare ME016823‌:
Apply a thin layer of clean diesel to the gasket for optimal sealing.
Install ME016823‌:
Hand-tighten, then add ¾ turn with a filter wrench (avoid overtightening).
Prime System‌:
Turn the ignition on/off 3–4 times to purge air from the lines.

Pro Tip‌: Inspect fuel lines for cracks during replacement to prevent leaks.
