  Fuel Banjos

  Banjos are used for leak off connections on Bosch Cav/Simms/Lucas/Delphi and Denso injectors. They are also used for lift pumps, filter assemblies and fuel line connections.

  Where access is limited for space for a direct connection, often a banjo and banjo bolt is used for a 90 degree access starting from 6mm up to 16mm. Size of supply pipe varies from 3 sixteenths to 13mm

  We stock a very wide range of banjos which go from 6mm to 16mm, and are all metal and can be single stem, double stem and triple stem. They fit pipe with an inside diameter from 3mm to 12mm.

  Non Return Valves

  Darwen Diesels stock a range of Non return or one way valves varying from 6mm – 13mm. One way valves can be used for a multitude of problems, mainly where the fuel has drained back to the fuel tank due to the system drawing in air overnight. This has been a problem for many years. Come the morning and the engine is turning over..... and over...... on the ignition key. We also do NON RETURN VALVES built into a filter, please check out our filter section for more information

  Fuel Supply Pipes & Fittings

  Darwen Diesels supply a range of fuel supply pipes and fittings.

  Symptoms of a problem with these parts are long cranking times when starting the engine, especially in cold weather, due to diesel draining back into the tank. This is often caused by excessively worn or perished leak off pipes. Although they are only low pressure, and they very rarely leak while the engine is running, these hoses can become worn and start to take air in when the engine is off, causing a situation where it takes a lot longer for the fuel to be drawn into the engine on cold starts. Replacing the pipe can be a very inexpensive and easy solution.

  A competent mechanic, before immediately assuming it is the pump, fuel filter or tank, would check the condition of the pipes as a damaged or leaky pipe can not only affect the starting and running of the engine but also be a potential fire risk.

  At Darwen Diesels we stock high quality cotton over braided as well as smooth fuel hoses suitable for unleaded petrol and diesel fuels. We also stock a very wide range of high-pressure steel pipe and emergency pipe (both 1.2m and 0.3m lengths). We also have a comprehensive range of multi fuel supply hoses which are available in varying diameters, nylon pipe, clear braid supply hose, and every type of leak off hose.

  If you have any difficulty locating any type of hose, fuel line or leak off pipe, please contact us and we will try to source that part for you. All of the pipes and hoses you see on our website are available for immediate, often next day UK delivery.

  Pipe Clamps

  At Darwen Diesels we have a wide range of injection pipe clamps in stock. We pride ourselves on having every type of pipe clamp you could possibly need for a diesel engine, we have both hinged and bolted 2, 3, 4 and 6 way injection pipe clamps available on the shelves ready for next day UK delivery.

  Due to the high compressions of diesel engines, vibration can be a problem causing fatigue in metals, especially with high pressure fuel pipes. Using a pipe clamp will help reduce the amount of flex caused by vibrations.

  If there is any type of pipe clamp you are unable to locate on the site, please do not hesitate to contact our sales/technical team. We have a lot of knowledge and experience in every field of diesel engine parts and assemblies and have the widest range in the UK today. We will be only too happy to help you and try to source that part or assembly for you.
