Understanding Fuel Pressure In The 1992 Ducati 907 Ie

The 1992 Ducati 907 IE is a sport-touring motorcycle that was introduced in 1991 as an upgrade to the 906 Paso. The 907 IE features a liquid-cooled engine, stronger crankcases, a revised clutch, and electronic fuel injection. It has a top speed of 177.3 km/h (110 mph) and can accelerate from 0 to 100 km/h in 12.1 seconds. The fuel pump is located inside the fuel tank and is responsible for delivering fuel to the engine. Fuel pressure is the force at which the fuel is delivered to the engine, and it is an important factor in the overall performance and fuel efficiency of the motorcycle.

Fuel pump issues

The fuel pump on a Ducati 907ie is located inside the fuel tank. Issues with the fuel pump can include a seized pump, a faulty relay, or a faulty ECU.

Seized Fuel Pump

If the fuel pump has been unused for a long time, it may become seized. This can be due to a lack of fuel lubrication during hibernation. The pump may need to be replaced if this is the case.

Faulty Relay

If the relays at the front of the bike are clicking, but there is no noise from the fuel pump, the issue could be a faulty relay. Swapping the relays can be a quick way to diagnose this issue.

Faulty ECU

If the bike has been off the road for an extended period, the ECU may be faulty and switching off power to the fuel pump. This could be due to the ECU sensing an issue with the pump or another unspecified reason.

Other Considerations

• Ensure the kill switch is in the "RUN" position.
• Check the fuel pump filter for blockages or install a new filter.
• Check the wiring and connectors for damage or corrosion.
• Ensure the fuel pump is receiving power from the battery.

It is important to note that accessing and repairing the fuel pump on a Ducati 907ie can be a complex task and may require specialised tools and knowledge. If you are uncomfortable performing these tasks yourself, it is recommended to consult a qualified motorcycle technician.

Fuel injection

The 1992 Ducati 907 IE was an improvement on the 906 model, which had issues with its carburetors. The 907 IE's fuel injection system was adapted from the 851 Strada, which provided vastly improved engine operation.

The key to burning the fuel cleanly is the ratio of air in the mixture. Fuel injection systems use electronics to automatically adjust this ratio, yielding multiple benefits. While fuel injection does not provide significantly more power or better fuel economy, it allows for more accurate control of the air-fuel ratio, resulting in a cleaner burn.

The 907 IE's fuel injection system, adapted from the 851 Strada, provided a significant upgrade over the previous carburetor system in the 906 model. This new system improved engine operation and addressed the issues with carburetion that plagued the earlier Paso models.

Fuel filter

The fuel filter on a 1992 Ducati 907 IE is located inside the fuel tank. It is a generic filter, identical to the one used in the R1150RS. A Mahle KL145 filter should work as a replacement, as should the following:

• BMW 16142325859
• BMW 13321461265
• BMW 13321460453
• Triumph 1240850
• Cagiva 88585
• Cagiva 42440041A
• Ducati 0241441800
• Ducati 42540041B
• Ducati 42540041A
• Mann-Filter MWK44
• Purolator F57123, PFC39
• UFI 3176000, 31.760.00
• Valeo 587013
• Knecht KL145, FB759, KL20
• Sofima S 1760 B, S1760B
• A.L. Filter ALG621
• Delphi FF0122
• Fram G3
• Hoffer 4255
• Meat & Doria 4255
• Quinton Hazell WF8140

The fuel filter is directional and should be installed correctly. It is also possible to blow through the filter in either direction.

Fuel tank

The 1992 Ducati 907 IE features a 21-litre fuel tank. The bike's fuel system includes a Weber-Marelli IAW 043 system that integrates ignition and electronic fuel injection.

The Ducati 907 IE was introduced in 1991 as an improved version of the 906 Paso, with a focus on enhancing engine and chassis performance. The 907 IE's fuel injection system, adapted from the 851 Strada, offered a significant upgrade over the carbureted system of its predecessor.

The 907 IE's fuel tank is an integral part of the bike's overall design and bodywork. While the tank has a capacity of 21 litres, the actual fuel consumption may vary depending on riding conditions and style.

The fuel system of the 907 IE is designed to provide a smooth and responsive riding experience. The Weber-Marelli IAW 043 system, known for its integration of ignition and fuel injection, ensures precise fuel delivery and engine management.

The fuel tank's capacity and the fuel system's efficiency contribute to the bike's overall range and performance. The 907 IE's fuel system, combined with its engine and chassis improvements, positioned it as a well-rounded sport-touring motorcycle.

The Ducati 907 IE's fuel tank and fuel system played a crucial role in the bike's overall performance and character, offering a blend of power, reliability, and riding comfort.

Fuel consumption

The 1992 Ducati 907 IE has a fuel consumption of 45 miles per gallon (mpg) or 17.8 kilometres per litre (km/l). This is a little disappointing, as the air-cooled vees used to return 50-55 mpg.

The 907 IE has a 21-litre tank, which means it can go 945 miles (approximately 1,521 kilometres) on a full tank.
