OTC 7211 Gauge and Hose Assembly

The OTC Gauge and Hose Assembly is specifically crafted to facilitate the testing of fuel injection systems, accommodating various fittings with its versatile design. It boasts a robust 3-1/2 inch dial capable of accurately measuring pressures from 0 to 100 psi. Crucially, the assembly is equipped with a built-in retard mechanism (100-150 psi range) that safeguards against potential damage from excessive pressure.

Key to its functionality is the disconnect fitting, which incorporates a check valve. This feature significantly reduces the risk of fuel spray during operation, enhancing both safety and efficiency.

Included with the assembly are a 6-foot bleed hose and a 30-inch pressure hose. The bleed hose is essential for purging air from the injection system, a critical step in ensuring precise pressure readings and optimal system performance. Additionally, the bleed valve serves a dual purpose: aside from air elimination, it allows for pressure reduction when disconnecting hoses, further simplifying operations.

Moreover, the bleed valve extends the utility of the gauge assembly by enabling the checking of fuel pump volume—a testament to its versatility and practicality in diagnostic and maintenance procedures.

In summary, the OTC Gauge and Hose Assembly is an indispensable tool for automotive professionals and enthusiasts alike, offering robust construction, precise measurement capabilities, and enhanced safety features through its integrated check valve and bleed system. Its compatibility with a wide range of fuel injection system fittings underscores its ultimate utility in diagnostic applications, ensuring reliable performance and accurate readings across various automotive settings.
