Description
Fine tune the fuel system on your Yamaha 1.8 liter platform with this billet fuel regulator block off pin designed for external adjustable regulator setups. When stepping up to higher boost, bigger injectors, or custom tuning, the factory in rail regulator can become a limitation. This T6 6061 aluminum pin cleanly blocks off the OEM regulator location so fuel pressure can be controlled by a remote regulator mounted where it is easier to access and adjust.
- Fits 2008 and newer Yamaha FX, FZR, FZS, VXR, and VXS WaveRunner models equipped with 1812cc HO, SHO, or SVHO engines.
- CNC machined from billet T6 6061 aluminum for a precise fit and long term durability in marine environments.
- Allows removal of the stock fuel pressure regulator so you can plumb in a high quality external adjustable unit for advanced tuning.
- Smooth, compact design simplifies installation and helps maintain clean, organized fuel rail plumbing.
- Perfect for turbocharged or supercharged builds, as well as naturally aspirated engines where consistent, tunable fuel pressure is required.
If you are ready to move beyond the limitations of the stock Yamaha fuel system, this block off pin is a simple but essential part of building a reliable, adjustable setup.
