How To Choose When Buying A Replacement Diesel Fuel Pump Or Diesel Injector
Diesel vehicles like anything mechanical can and do have parts which wear out or develop problems. Two of the most expensive parts to replace are related to the fuel injection system. Diesel Pump is responsible for the pumping of the correct amount of fuel, at the right pressure and time from the tank into the injectors. From the injectors the fuel is then injected. This is then injected into the combustion chamber. The result is combustion of the fuel which is what powers the piston to make the vehicle move. When looking to purchase a fuel pump or diesel injector, there are a number of factors that will influence your final choice.
Price and quality of the replacement part will be the most important factors for most people. Buying a new diesel pump or diesel injectors could prove to be more expensive than the value of the car especially if the vehicle is old. Parts exchange offers a cost effective means of replacing worn or damaged parts, usually a repaired or remanufactured part is swapped for your worn fuel pump or injector, The quality of the replacement parts can vary depending on a number of factors.
Some thing to look for when purchasing fuel pumps or injectors on a exchange basis are warranty on the replacement parts. Is the company offering the exchange approved by the large diesel pump and diesel injector manufacturers? Bosch Denso Delphi and Siemens produce fuel pumps and injectors for approx 98% of all vehicles on the road. Usually a company will only be approved after they have invested significantly in diesel test bench's, purchased the latest pump and injector data from the manufacturers. Purchasing from a approved company ensures the diesel pumps and injectors have been repaired to the exact same standard as when it left the factory, all parts used will have been supplied direct by the manufacturers. Buying from a approved dealer /repair agent ensure that the company has been trained by the manufacturers. Beware of self proclaimed diesel specialist if they were as good as they claimed then the manufacturers would have been calling to ask them to join there approved servicing agent network. If for whatever reason you do not have a diesel pump or diesel injector to swap these companies may still be able to help, but a extra fee will usually be charged to cover the cost of sourcing and restocking the part you have just taken off the stock levels.
Another benefit of the parts exchange program is that this is more friendly for the environment and helps to reduce carbon emissions.
2ND hand parts sourced from places like eBay or the local scrap yard are the final option, usually have something like this on the advert "pulled form a running vehicle not tested". This is really pot luck as the seller would more than likely have little knowledge as to the condition of the pump or injectors. A fully equipped fuel injection workshop costs hundreds of thousands. To test a diesel fuel pump or diesel injector requires both one of the test bench's and specialist knowledge on how to operate the machine, most 2ND hand parts sellers sell the odd fuel pump or injector, so may not be the best person to guess a fuel pump or diesel injectors condition.
