    Low pressure PT sensor connector color is brown.

Install

  1. Lubricate the low pressure PT sensor threads and O-ring with ND-11 oil.
  2. Hand start the low pressure PT sensor until the O-ring contacts the supermanifold.
  3. Gradually hand tighten the low pressure PT sensor while slightly backing off to walk the O-ring into the fully seated position. This will avoid pinching the O-ring on the outside edge of the manifold, which can cause a leak,
