Product Details

The Airtex 5G1019 is a direct-fit replacement fuel injection pressure regulator engineered to restore proper fuel system performance. This regulator maintains the precise fuel pressure required for efficient combustion, protecting fuel injectors and the fuel pump from pressure-related stress and premature wear.

Constructed from durable metal with a threaded inlet and push-in outlet design, this regulator is a non-adjustable, clamp-mounted unit built to match original equipment form, fit, and function. It features a 14.0mm (0.55 in) threaded inlet port and an 8.0mm (0.31 in) push-in outlet port for straightforward installation.

Key Features:

  • Metal construction for durability in demanding underhood environments
  • Threaded inlet (14.0mm / 0.55 in) and push-in outlet (8.0mm / 0.31 in)
  • No gauge port — matches original equipment configuration
