Diesel Pump Repairs

Over the last few years, there have been considerable advancements in diesel fuel injection systems. Unfortunately, this adds stress to the diesel pumps’ internal parts due to the high fuel pressures they have to produce.

An area of uncertainty is trying to diagnose engine running faults by knowing the condition of the high-pressure diesel pump. We can test high-pressure fuel pumps helping to determine their condition and whether it could be a cause. Modern fuel pumps are tested and repaired using our state-of-the-art technology at our dedicated workshop in Shropshire.

With over four decades of experience in the UK’s diesel fuel injection industry, we can also repair older diesel fuel pumps, which is quickly becoming a rare service. For leading diesel fuel pump testing and repair services, trust the experts at United to get you back on the road.

Common Issues of A Faulty Diesel Fuel Pump

There are a number of indications of a potential faulty fuel pump. Many customers will experience the same fault and may already know the cause but, in some instances, you’ll need a specialist who can investigate the fault for you.

Did you know – modern fuel management systems will inject fuel up to 7 times in one firing cycle? This is why fuel pressures are so high – injectors must react quickly!

At our dedicated workshop in Shropshire, we use the latest technology that allows us to test fuel injectors and pumps. Then we’ll inform you of the test results and advise you on what would be the best course of action to take. Should the car’s fuel pump be unrepairable, we can offer exchange units or the supply of new units.

From cars and commercial fleet vehicles to agriculture/plant and marine; we’ll inspect your component to discover the issue and once diagnosed, we’ll offer a repair, exchange or a new component. What makes us different is if we know we can repair your fuel pump, this is always the first option we’ll give you.
