Finger tight? Really? Sounds like one of those forgetful mistakes I make now and again. They cause me to re-evaluate how long I can continue making my own repairs to things my family's safety depends on.

Yes, the rattle gun is to me an essential for the fuel filter change. Trying to use wrenches to counterhold that filter when loosening or tightening has, in my opinion, destroyed more of those short nylon hose assemblies connecting the filter to the pump than any other goof.

With time, you will get the feel of the impact tools so they will be useful installing as well as taking things apart. One of the hurdles to that end, I think, is learning to watch the socket as it advances the bolt to correlate that with the angle you achieve by turning one by hand with a ratchet. Otherwise, with varying air pressure and little experience, torque is sometimes difficult to interpret.
