A: Watch for rough idling, hard starts, or too much smoke. These are early red flags. It's smart to check your pump every 6 to 12 months so you can catch issues before they turn serious.

A: It can. A modern pump delivers fuel more precisely, which can boost mileage by up to 7 percent. Pair that with clean filters, and you'll see the savings add up, especially on high mileage vehicles.

A: A well-made pump can last anywhere from 500,000 to a million miles. Keep up with regular maintenance like priming and filter changes, and it'll serve you for the long haul.

A: Driving with a faulty fuel injector isn’t something you’ll find many motoring experts recommend, as you run the risk of more problems as a result. We’ve already mentioned the issues of misfires or rough idling, but you could also find that the injector problems cause you to stall or even flood the engine. In this case you’re likely to be put in a much more dangerous position if you’re stranded, so it may be better to not take the risk at all and get it fixed before you undertake any major drives.
