If you find yourself low on cash when it comes time to change the fuel filter, they aren't to expensive at the parts stores (I think my trooper FF was $9), and it takes 15 minutes to replace. It can get kind of messy because the fuel line is pressurized, but once you've got one end of the line off, it gets pretty easy from there. I use golf tees to plug the lines while I'm changing out the filter so gas doesn't get all over the garage.
