Tech Tips (In-Tank Fuel Pump Pressure Specified Value):
This document informs Specified fuel pump pressure value from the in-tank (low side) fuel pump is 3.7 bar or higher when tested.
Ensure fuel pressure is checked with a gauge that measures absolute fuel pressure such as the VAS 6550. If fuel pressure is checked with a gauge that measures relative fuel pressure, the gauge may incorrectly indicate pressure is below specified value.
