Where should you install the pressure gauge to check for sufficient pump pressure on a self-contained dispensing unit?

The correct choice for installing the pressure gauge to check for sufficient pump pressure on a self-contained dispensing unit is to place it on top of the meter cover. This location is advantageous because it allows for an accurate reading of the pressure that is delivered to the dispensing unit. By monitoring the pressure at this point, you can ensure that the system is operating within optimal parameters and can identify any potential issues that may arise in the dispensing process.

Placing the pressure gauge on top of the meter cover provides a direct line of sight into the pressure being exerted as fluid moves through the system, which is essential for troubleshooting and maintenance. It allows the operator to easily monitor performance during operation and helps to ensure that the flow rate and pressure are adequate for effective dispensing.

In contrast, options such as the bypass valve or the float chamber may not provide an accurate reading of the system pressure under normal operating conditions. And while the pump discharge line might seem logical, the top of the meter cover is specifically designed to facilitate such measurements under typical use conditions.
