With the #1 cylinder’s exhaust valve in the correct adjustment position; From front to back (1 through 10), the valves are adjusted in the following order. Correct injection timing is critical to good engine performance, fuel economy and EGTs.
What should drive pressure be for injection pump?
Drive pressure higher than 2:1 has two major effects, it drastically increases exhaust temperature and increases engine pumping losses. Both increase stress on the engine and reduce horsepower. The perfect ratio is 1:1 but 1.5:1 is also very good.
When do I need to adjust the injection pump fuel?
After tensioner removal, the camshaft sprocket may be slid forward to the point just before complete removal from the camshaft to exchange the woodruff key. Adjustment must be performed at a maximum interval of 14,000 miles. I suggest an interval of 10,000 miles.

Can you change the power of an injection pump?
The stock mufflers are a straight-through, unbaffled, design and the diameter is already large even compared to modern cars. Installing an aftermarket “cold” air intake, installing a larger diameter exhaust and/or removing the mufflers will produce a 0hp change in power. The only change they will produce is noise.

What should the temperature be for an injection pump?
The longer you run hot the more damage excessive temperatures will do and it won’t be obvious there is a problem until its too late. 1250*F (675*C) is a safe limit for continuous output, 1400*F (815*C) is acceptable for short intervals (under 5 seconds).

This is caused by a lack of fuel to spin the turbo fast enough. Drive pressure higher than 2:1 has two major effects, it drastically increases exhaust temperature and increases engine pumping losses. Both increase stress on the engine and reduce horsepower.
What’s the fuel pressure on a Mercedes Benz?
A great and affordable gauge that we have used in the past is this Actron Fuel Pressure Gauge which works on Mercedes-Benz cars. Turn the engine off and connect this gauge to the Schrader valve test port shown in the picture below. Start the car and you should be able to get around 60 psi.
What should I do if my Mercedes Benz won’t start?
