How to Identify Your Pressure Port Thread:
The image above has circled the pressure port plug to check:
Loosen or Remove the plug and use description below to identify your pressure port option:
• If the plug has a flat shoulder/ledge that stops against the engine and may include a washer, crush washer, or o-ring then your pressure port option is "straight thread".
• If the plug does not have have a washer, crush washer, or o-ring then it is most likely a "tapered thread".
Important note about removing the oil pressure plug:
Some customers find it easy to remove this plug and others find it difficult. This is why we highly recommend removing the plug to verify the thread before ordering a kit. Here are some tips submitted by our customers to help with removing this plug:
• Some suggest cutting an allen wrench to shorten the length to allow for additional room to use a breaker bar or other leverage device.
• Some recommend slightly lifting vehicle to drop suspension, this gives a little more room to work around the area.
Installation Guide:
