This SAE Recommended Practice promotes uniformity in the evaluation and qualification tests conducted on fuel pressure regulators and pressure dampers used in gasoline engine applications. Its scope is limited to fuel pressure regulators and dampers used in automotive port and throttle body fuel injection systems where fuel supply pressure is below 1000 kPa. It is further restricted to bench type tests. More specifically, this document is intended for use as a guide to the following: a Identify and define those parameters that are used to measure fuel pressure regulator and pressure damper characteristics of performance.

This SAE Recommended Practice defines the tests for three basic categories of pump characteristics. These are the basic functional performance tests, the pump limitation tests and the pump integrity tests. The basic functional tests included are three individual tests, with the first being for pump speed, current draw, and electrical resistance. The other two individual tests are for the deadhead pressure and the delivered fuel flow rate at the rated delivery pressure and voltage. The included tests for pump limitations are individual tests for hot fuel handling, cold magnet knockdown, load dump transient, electrical interference, and reverse flow leak. The testing for pump integrity includes individual tests for vibration, temperature cycling, internal fluid compatibility, and operational durability. These 12 individual tests provide a characterization of the particular pump.
