I think you're overlooking some other cause, but if you want to add an external filter, consider one for a Chrysler product. They easily last the life of the vehicle. One for an '88 Caravan connects with just a pair of short rubber hoses and four clamps. (Use fuel injection clamps, not the common worm screw "aircraft" style clamps because they will bite into the rubber and cut it). The filter has a mounting bracket attached so you'll just have to drill one screw hole to run a bolt through. When you cut the metal line, use a file to round the ends so vibration doesn't force them to cut the rubber hoses. File some notches for the hoses to grab onto so they can't be forced to slide off from the pressure. I use a double flaring tool for brake line to make a small bulge on the end of the steel lines.
There are similar filters on newer Chryslers that use quick connect fittings. You can buy four of them as a repair kit from the dealer. Two are straight and two are curved. You use the correct pair for the application and have two left over. They don't save much time over the clamps, and sometimes road salt and dirt plugs the springs and makes the connectors hard to remove. You're much better off with the older style and clamps.
