i think the dampener and regulator were around $100 for both including shipping. i didn't replace the fuel lines because they looked great. the entire job is a 2 hour job in a driveway from hood up to hood down.
here's a tip... while your injectors are out.. you'll need to plug the fuel rail up. i went to an auto parts store and got one of those rubber donuts that are used to hang exhaust brackets and components by. you know the ones... they're like 1/2" in diameter.
i just cut one in 4 pieces and then plugged each injector hole with a piece of rubber. not one drop of fuel leaked out at all.
affordable efi told me that all 4 injectors needed cleaning, but one of them was really bad. after the cleaning they were all unbelievably balanced. i distinctly remember them saying that they were amazingly close like .1% or so. it was well less than 1% difference across all 4 injectors. i have the paper somewhere.
