I can't find the fuel filter on my 2004 1500 4X4, nor do I find any information in the owner's manual. It's gotta have one..... right? The only place that it could possibly be is up above the driveshaft, muffler, and gas tank- looks like that's where they put the fuel pump these days instead of in the tank. But, I did not take the cover off to look. Seems like a bad spot- what ever happened to putting it along the frame rail so it's easy to change? Thanks for helping.
