The stock 3SGTE fuel pressure regulator flows about 250 lph efficiently. This means anything bigger than a Walbro 255 will overwhelm it, and fuel pressure will be higher than the set point. This regulator is rated for up to 1000hp of flow and keeps fuel pressure in check with a larger fuel pump.

Includes mounting bracket, and gauge port adapter. Does not include fittings, these are available separately.

If mounting remotely, you need 2 6AN Adapters.

If mounting on top of a DW fuel filter, you need 1 6AN Adapter and 1 Filter Adapter.
