What should I look for/ask when purchasing fuel injection equipment
- Is the company an authorised service agent for the product you are supplying?
- Do they have the necessary test equipment and trained technicians to service the product?
- If the product is a ‘reconditioned’ unit which parts if any do you replace during this process and what warranty do I have?
- Are the parts fitted genuine OE parts or none genuine copy parts?
Here at FDS we can confidently answer these questions.
Do I need to have an exchange pump or injector?
How can I identify and order my pump or injector?
As a consequence we would always request part numbers from the old unit. Where there is ambiguity we would prefer not to supply a product for it to later return as incorrect.
Unfortunately there is no commercial vehicle registration look up so we would require the Bosch/Delphi/Denso number or OE manufacturer part number.
WHAT’S THE PART NUMBER PLEASE?!
How do unsuitable fuels affect fuel injection equipment?
The use of Bio fuels and other types of alternate diesel fuel should be seriously considered before use in any diesel vehicle. The consequences of incorrect fuel can be catastrophic and may invalidate the warranty supplied by the manufacturer of the fuel injection system; additionally the quality of fuel used directly affects the fuel economy of your vehicle and the longevity of the fuel injection equipment.
In extreme cases injectors can last minutes if run on dirty fuel, that with water or oil in, petrol or very high bio content. On the vehicle this may show itself as smoking, non-start, misfires; on the test bench there may be limited or no-delivery or reduced fueling even the though the nozzle may be days old. In all cases warranty will be rejected by the OE supplier.

The correct fitting of pumps and injectors is critical to the short and long-term performance of the product supplied. For example fitting common rail injectors require critically clean environments, spotlessly clean diesel, replacements high pressure pipes and quality re-coding equipment. Failure to clean out bore areas for injectors may lead to incorrect seating leading to combustion gases and fuel passing the seating washer. This will cause running issues and lead to carbon build-up around the injector.
Depending on the technology being worked on certain exacting procedures should be followed i.e. Bosch PD injectors, Delphi common rail injectors, Bosch VP pumps etc.
Poor fitting may damage pumps/injector very quickly; poor fitting causes the damage which is then diagnosed as “warranty” of the product. In 99% of all cases this is shown as rejected warranty.
