Reviews

  • I have an 89 non intercooled 12v cummins, I am wondering if the spray pattern in correct? Because I know that the intercooled cummins have a different spray pattern

    Jason Leuer | 12/30/2024

    Yes spray pattern will be correct.

  • What are the proper supporting mods to start with stage one injectors? What do I need to do in order to get the most out of the injectors? My truck is a 1990 w250 12v.

    1st is to make sure your VE pump is capable of the upgrade. you can  Add a fuel pin and 3200 governor spring to help support the increase in fuel demand.
