Where is the fuel filter on a 2012 Dodge Ram 3500?

On every car, no matter the engine size, you’ll always find the fuel filter situated between the fuel tank and the engine. The job of a fuel filter is to filter any unwanted dirt and debris out of the fuel before it reaches the engine. 
On the 2012 Dodge Ram 3500 6.7-liter diesel engine, there are two fuel filters. One of them is under the hood on the driver’s side of the engine near the firewall, while the second one is positioned in the rear of the vehicle near the fuel tank. The filter under the hood can be a bit tricky to get to because it’s in a relatively tight spot, but with practice, it can get easier. 
Maintaining clean and functional fuel filters is essential for the health of your engine. Clogged filters can restrict the flow of fuel to your engine, causing it to work harder than it would otherwise have to. Excess debris in the filters also runs the risk of more contamination traveling along with the fuel and creating problems throughout the system. 

Signs of a clogged fuel filter

If you’re having a hard time pinpointing the reason for your Ram 3500’s performance issues, you may want to consider inspecting your fuel filters. 
Here are some common symptoms of a clogged fuel filter that needs to be replaced: 
  • Difficulty starting the car
  • Loud noises from the fuel pump 
  • Rough idling, sputtering, and engine misfires
  • Vehicle stalling
  • General fuel system failures
  • Strong odors from the exhaust
Aside from contaminating the engine, a clogged or otherwise bad fuel filter can reduce your fuel economy and create more emissions. It’s important to replace a bad fuel filter as soon as possible. 

2012 Dodge Ram 3500 fuel filter replacement

The recommended
replacement interval for a fuel filter
is two years or about 30,000 miles, whichever comes first. However, keep in mind that your driving conditions are likely to impact the actual replacement interval. If you frequent dusty dirt roads and trails, your fuel filters are picking up more debris than someone who sticks to well-maintained boulevards only. 
Happily, both of the fuel filters on a 2012 Dodge Ram 3500 are positioned independently of the entire fuel pump, so replacing them is usually pretty simple. 
New fuel filters for the Ram 3500 cost around $55 each, so if both filters need replacing and you’re able to do the replacement, you’ll be looking at a bill of a little over $100. For those of us who’d rather leave fuel filter replacements to the professionals, we’ll need to factor in another $55 to $70 for labor costs
Ultimately, how much you’ll pay for a fuel filter replacement depends on where you go to get the parts and where you go to get it done. Try a few different auto supply shops to find the best price or ask your regular vehicle servicer how much they charge to replace the fuel filters for your vehicle. 

How to save on Dodge Ram 3500 insurance costs

Just like with new fuel filters and other car parts, shopping around for your car insurance will help to guarantee you find the best price. It’s recommended that you shop for car insurance every six months to maintain the best rates for your desired coverage—but we understand that calling company after company after company to collect quotes twice a year probably sounds exhausting.
