Anyone know the correct line pressure for the common rail for the direct injection of petrol on FSI and TFSI engines? Thanks in advance.

Part way down:
- Two fuel pumps are used for the Audi FSI. A primary pump operates at
- 6 bar (87 PSI) and is activated when the driver's door is opened. A second
- pump is operated on demand and uses a single piston pump to push fuel to
- a common rail that feeds all injectors. This pump can develop between 30 and
- 110 bar (435 to 1600 PSI) depending on engine requirements.
