Show original supplier description
The LC Engineering Fuel Pressure Regulator Gauge Kit is a vital component for Toyota truck owners running a Weber carburetor. Weber carburetors function best within a narrow fuel pressure range of 2.5-3psi, and this kit provides the tools necessary to achieve and maintain that optimal setting. Included in the kit is a genuine Weber regulator, a custom-made fuel line T-fitting manufactured in the USA, and a reliable low-pressure dry gauge. This combination allows you to precisely measure the fuel pressure being delivered to your carburetor, aiding significantly in the tuning process. The aluminum construction ensures durability for underhood applications. A note of caution is provided regarding the factory fuel line, which is slightly smaller than the regulator/carb fuel line. Gentle pressure is needed for connection. This gauge is intended primarily as a diagnostic tool; for a permanent installation, part #1035055 is recommended.
