METCO 2005 & Newer Ford Fuel Block Kit with Gauge This convenient billet adapter mounts directly to the factory (or aftermarket equivalent) fuel rail, sandwiched between the rail and the OEM fuel pressure sensor. The fuel block seals with OEM-style O-rings, so no gaskets or sealants are required. The installation is a quick and simple affair. The CNC-machined block is tapped with two 1/8" NPT ports to provide a convenient tap for a fuel pressure gauge, a fuel source for a nitrous system, or both. This kit includes a 1.5" carbon fiber-faced fuel pressure gauge that can be mounted to the fuel block, and a stainless steel pipe plug (not shown) to seal the unused port if necessary. The kit includes the necessary installation hardware, and the block is black-anodized for long-lasting surface protection. Note: This block is available separately under Metco Motorsports PN MFF0004.
