Whats the maximum fuel pressure in a Gasoline and Diesel engine?

the modern fuel pumps deliver fuel at a pressure range of2.5 to3.5 bar

On diesel engines, it features a high-pressure over1,000 bar  15,000 psi.

on petrol engines with fuel pressures up to1,800 bar or26,000 psi.

In Gasoline Engine the air mixture is.7:1. but in the Diesel Engine's mixture is to high.Gasoline Engine is Spark Ignition(SI Engine) and Diesel Engine is Compression Ignition(CI Engine) .

There are2 fuel pumps.. one is low pressure and another high pressure.. low pressure pump of petrol and diesel can generate pressure from2.5 idleing to5 bars full throttle. And high pressure on petrol is around120 bars and on diesel is150 bars.
