Where is the fuel filter on a 1999 Jeep Grand Cherokee Limited?

There are 2 filters.

  1. One is on the end of the pickup tube inside of the gas tank.
  2. The second is in-line, above the front edge of the gas tank, inboard of the frame member. It is part of the fuel regulator/filter assembly.

Here's a diagram:

This second filter is the one you should remove and inspect. Probably unhealthy, but I generally blow through them to see if they're clogged (it's the best test I've found- if it's hard to blow through, or your ears pop, replace it!).

Oh, your new filter should have some simple instructions inside the box.
