OEM DDEC 2-4 Fuel Restrictor Fitting 8929725

On DDEC II–IV, this fitting is the only thing that sets fuel pressure. It’s essentially your fuel pressure “regulator.” A lot of customers have found theirs drilled out by clueless individuals trying to increase power. Drill it out, and pressure control is gone.

If you’re fighting an unexplained power issue and feel like you’ve tried everything, it’s worth checkling into or ordering one to try!
