Where is the fuel filter on 1994 Dodge B250 5.2 318 engine Ram Van?
Under the van about midway down the passenger side bolted to the frame. The easiest way to find it is to follow the fuel lines back from the engine compartment.
What could cause a rattle or knocking in front end of Dodge Ram B250 not when idling but when going slow?
Sometimes that is related to the type of oil you are using. I did change brands several times and also went synthetic until I found the one that works for me. For several years I used conventional Castrol GTX 10w 30; after doing my homework I finally found that Mobil 1 Synthetic 15w 50 does the job. I have a 1994 B250 with 190.000 miles
