The Holley Sniper EFI Stealth 4150 Braided Fuel Crossover Kits are designed to be used with either Sniper EFI Stealth 4150 or Terminator X Stealth 4150 systems. These pre-assembled fuel crossovers are designed to provide ample clearance between the fuel hose and the TPS sensor mounted on the side of the throttle body. They come in two variations. The 534-236 kit contains a braided fuel hose, with crimp on ends for a leak free installation, two fuel bowl standoffs and a T fitting, making installation clean and easy. The 534-237, comes with the same crimped fuel hose, but also includes a black anodized billet fuel regulator, preset to 58.5psi and a mounting bracket. This kit allows users to mount the fuel regulator right off of the side of the throttle body, and the bracket mounts to the base of the throttle body, providing a quick and easy installation of a fuel regulator.
