Oh, enough with the sensitivity crap today. Do you want a clean, working fuel system or just another Internet daily affirmation?
I'm in the 'read-three-words-and-reply' mode today.
OK, I am assuming you have a 1999/2000 model with the external fuel pump. Whether you are doing regular maintenance or are fixing problems, I suggest going with an external filter, as in the article I linked above. That will save you $35 for the dinky Suzuki filter. You can either get a GM/Ford in-line filter or go with the more expensive, but clean-able K&N. It will probably be easier to just get a car one and replace it every other year. I listed most of the o-ring sizes in the link. The only seal you might want to order is the packing seal that goes between the assembly halves. It's ~$15 from the dealer. You can re-use the old one, but the problem is that the fuel expands the seals, making them difficult to replace. Place them in the freezer for a while to shrink them. The o-rings are cheap enough to replace, though, so you do not need to bother with that, just the packing seal, if you decide to re-use.
I would also go ahead and get new fuel injection hose and FI-hose clamps. Those are the ones that come around like a 'G' with the screw, as opposed to the slotted ones that tear up hoses.
As an idea, you might consider replacing the four Phillips-head screws on the pump assembly and the two regulator screws with hex or Allen head screws. That will make re-assembly and dis-assembly in the future much easier.
Feel free to email me if you have more questions along the way. I am pretty busy, lately, but I promise to read more than three words before hitting 'reply' this time.
