8.8.5 Fuel prefilter – Pressure ratios

WARNING

Fuels are combustible and explosive.
Risk of fire and explosion!
• Avoid open flames, electrical sparks and ignition sources.
• Do not smoke.
• Wear protective clothing, protective gloves, and safety glasses / facial protection.

WARNING

Liquid or gaseous media, e.g. fuel, are poisonous.
Escaping vapors of highly volatile media, e.g. fuel or ether.
Risk of fatal injury through swallowing; risk of poisoning through inhalation; irritation to eyes
and skin!
• Seek medical attention immediately; do not induce vomiting.
• Do not inhale vapors or mist.
• Wear protective clothing, protective gloves, and safety glasses.
• If contact is made with skin, wash off with water and soap.

Pressure ratios

Note:

• If the fuel prefilter is above the full level of the fuel tank, during engine operation the fuel pressure in the

filter is lower than ambient pressure (vacuum).

• If the fuel prefilter is below the empty level of the fuel tank, during engine operation the fuel pressure in

the filter is higher than ambient pressure (overpressure).
In the case of overpressure, fuel can escape under pressure.

u

The pressure ratios should be known from commissioning. Pressure ratios can be checked with the engine
shut down.

Checking pressure ratios

1.

Stop engine and disable engine start.

2.

Carefully open threaded vent plug (1) slightly:

Result:

• If no fuel emerges, this is an indication of

vacuum or pressure balance.

• If fuel emerges, this is a sign of overpres-

sure.

3.

Collect fuel as it emerges.
