Porsche vehicles are considered to be luxurious and fast – qualities that true car enthusiasts can appreciate all over the globe. Although they’re revered for the exceptional driving experience they offer drivers, they tend to run into a few common issues that Porsche drivers should know about. One such problem that Porsche cars may experience from time-to-time is fuel pump malfunction.
No matter what type of car you drive, the fuel pump is essential to your vehicle’s performance and general functioning. When the fuel pump runs into performance problems, it may lead to fuel leaks that can cause your vehicle to become highly inefficient, wasteful, and downright dangerous. While problems with the fuel pump can be addressed rather simply in some cases, the origin of the problem will highly influence how “simple” the problem is to fix. In this article, we’ll go over why fuel leaks occur, what you should be aware of in terms of symptoms, and how you can address this issue in your own Porsche.
What causes fuel pump malfunction or failure?
The first thing to do when you bring your Porsche in due to a fuel leak is to determine where the problem originated so that the root of the problem can be addressed, not just the symptom. There are several avenues for fuel leaks to occur in your Porsche, and depending on the specific type of Porsche you drive you may be at a higher risk of running into fuel pump failure. The fuel system is complex and contains multiple different areas where fuel leaks could occur, including: hoses, fuel lines, valves, diaphragms, etc. Usually fuel pump leaks occur because of old fuel system components that require replacing – and in some Porsche models like the older Cayenne SUVs this is a serious, recurring problem.
Common accompanying signs of fuel leaks
Fuel leaks may be obvious – you may notice puddled liquid beneath your car in certain areas – but fuel can evaporate rather quickly when exposed to the other elements in the environment, so it’s important to be aware of other signs of fuel leaks or fuel pump failure.
Decrease in fuel efficiency
If fuel is leaking, that’s fuel that you’re not using; this drastically affects how your Porsche utilizes fuel and how quickly you need to re-fill your tank. If you become aware of frequently having to fill the tank or notice that your fuel gauge becomes low quicker than usual, it’s reasonable to suspect that you’re either losing fuel or something is going on within the fuel system. You may also smell a strong odor of gasoline in the cabin or just outside your car.
Lowered performance output
Unfortunately, when your car begins leaking fuel it nearly always leads to performance issues. Usually we don’t invest in Porsche vehicles because of their exceptional gas mileage, but because of their high performance standards. Here are a few performance issues you may encounter the longer the issue goes unaddressed:
o Engine starting issues
o Losing power upon acceleration
o General rough running
If you begin to experience any of the above-mentioned symptoms in your car, it’s critical to have it checked out by a specialist immediately to ensure your safety on the road.
Higher-than-normal engine temp
As fuel leaks, it causes strain on the engine due to the lowered amount of fuel entering the engine for combustion. This often causes the engine’s temperature to rise beyond what is normal. The internal temperature of your engine shouldn’t fluctuate drastically, and if you do notice this, it’s critical to bring in for an inspection before engine damage occurs.
What you can do to prevent fuel leaks
As a responsible driver and Porsche owner, it is imperative that you remain proactive regarding your vehicle’s care and overall health. Here are a few pointers that can help prevent fuel leaks:
• Appoint an experienced a Porsche specialist to handle maintenance and repairs
• Don’t wait to address fuel leak concerns
• Follow your car’s specific maintenance schedule
• Attend to fuel system inspections and maintenance tasks regularly – especially if your Porsche is particularly susceptible to leaks
