Failure to deal with a bad fuel pump in time may leave you having to pay for expensive repairs as well as experience lower gas mileage or total engine failure. On the failing end of it, repair prices could fluctuate between $400 to$800 for a brand new fuel pump (parts & labor), according to car fashions. But letting the problem fester can be a costly oversight, as a failing pump will take out its wrath on other parts like fuel injectors and filter — and even your catalyitic converter. This, they said, would increase the chances of further damage by 30%, which based on a $1000 repair could total more than $1,500 to fix.
A fuel pump that is having to work hard just to maintain enough pressure will start seeing a decline in its fuel efficiency. Poor Fuel Economy — If the fuel delivery is inconsistent from a weak pump, this will result in incomplete combustion and decreased gas mileage. Drivers of vehicles with failing pumps may experience 10-15% loss in fuel efficiency, which can cost hundreds more dollars a year in higher gas bills for high-mileage drivers. A single failing pump could drive annual fuel costs up 20%, according to a car maintenance cost study.
But it could harm engine performance, and reliability too. Failing fuel pumps frequently run the engine out of gas and cause misfires, stalling or extremely slow cranking when you try to start it. Such unpredictable behavior can be a safety concern, especially in scenarios that call for quick acceleration or constant speeds. Authorities point out that the risk of stalling without any warning would be much higher than for vehicles with faulty fuel pumps, which could cause a crash and get drivers stuck. Not to mention, the cost of emergency towing and then repairing a vehicle will be more expensive than had you decided not to change out your fuel pump in advance.
If you have a high-performance vehicle, a poor fuel pump performance is restricting the potential of your engine since steady fuel pressure significantly affects horsepower. This means the failing pump limits how much power can be produced in a vehicle by lowering throttle response and acceleration. Frequent tune-ups as well as replacing your Fuel Pump is crucial to keeping away from more expensive repairs and maintaining the performance of a engine at highest efficacy.
