I changed my fuel filters last night which turned out to be a pain in the butt. The instructions I had which I got from this great website said to jack the driver side axle up to move the drive shaft out of the way enough to gain access to the filter on the frame rail. Well tried this with no success, so I ended up just dropping the front drive shaft which made it alot easier and in no time had both filters changed. My truck seems to run alot better now they are changed. Is it normal for the truck to surge a little after changing the filters? It did it for a while but now has seemed to stop.
