## Description

Fuel Filter, 4-3/32 x 3-3/8 x 4-3/32 In

Review: Great filter - This is a really great product. The filter catches anything that will get into my gas tank. Baldwin filters are the best and always reasonable on the price.
Review: Quality filter makes a happy truck! - I just recently purchased a 2005 Dodge Ram 2500 4x4 with the 5.9 Cummins diesel engine in it. After joining a bunch of forums, reading posts on various sites, and asking some local shops, the majority of everyone I came across recommended this Baldwin PF7977 fuel filter when changing out the stock fuel filter with the stock fuel system on my truck. I guess it is a common problem with the diesel engine in my truck that the stock fuel filter it comes with doesn't filter out to much of the garbage in the fuel such as contaminants or water and it will eventually make it's way to the injectors causing them to fail along with other engine problems. This fuel filter I believe it said was a 5 micron filter which is the absolute best for the fuel filtration on a 2005 Dodge 2500 along with the quality Baldwin brand. It was super easy to install and made my truck run 10x better, I recommend everyone changing their fuel filters with every other oil change just to be safe than sorry and to keep your truck happy. One small thing I noticed about this in the label it states it is a spin on filter when in fact it is a clip in filter that just snaps into place.

### ⭐⭐⭐⭐⭐ Fits and works like a champ 2004 Ram 3500 5.9 Cummins
*by N***Z on October 9, 2025*

Original owner of 2004 Dodge Ram 3500 with 5.9 Cummins diesel engine. Could not find any fleetguard fuel filters locally, so jumped on Amazon and came across these Baldwin 5 micron filters while the fleetguard are rated at 7 micron rating. Looked up Badwin filters and a respected brand so I ordered a 2-pack which was cheaper than 1 fleetguard filter ordered online. After 3 months of install, quite pleased with this filter. Seems to be just as good If not better than OEM and retail Fleetguard and cheaper. Give these filters a thumbs up.
