Have a question about this product?

  • Question

    Do you offer one of these in the 43psi range for use with my terminator system?

    By Mark B. on April 3, 2020

    Answer
    We do not offer a unit for 43 psi. You can adjust Terminator X systems to accommodate almost any fuel pressure in the software.
