GTR STG2 to STG3 Fuel System Upgrade
The Visconti Tuning GTR Fuel Hanger Upgrade allows you to convert your existing STG2 dual pump fuel system into the STG3 triple pump configuration.
By replacing the factory plastic hanger with our billet upgrade, the last restriction inside the fuel tank is removed, allowing your fuel pumps to flow freely while maintaining factory functionality.
This upgrade is designed for high horsepower R35 GTR builds looking to support 1000+ WHP on ethanol.

How the triple pump system works
Using our billet bracket, the third Walbro pump is mounted next to the factory fuel basket and connected to a HydraMat. The HydraMat allows full fuel flow even at very low fuel levels, ensuring the third pump continues supplying fuel even after the primary pumps begin to uncover.
