2007 Dodge Dakota 4 by 4 quad cab location of inline fuel filter
It's part of the fuel pump assembly in the gas tank. So unless you have an issue, I'd leave it.
Yup cartridge type pump, filter , sender all in one and really spendy after market pumps NOT recommeneded as a improper fuel pressure condition will result. (Ie)poor runability,stalling, and codes such as ox sensor,and random cyl misfire. Ect. As tom said wait till the pump fails
