Most of the people who read this board work on their own cars.We ask questions concerning all aspects of car repair.So here's the deal.If you read a post about brake repair and your brakes are ok,go out and spray some pb blaster on all the fittings and bolts.If you read something about a water pump repair or suspension repair and your system is ok right now,go out and spray some pb blaster on all the nuts,bolts,lines,fittings.This is especially true for that under the car fuel filter.Do this regularly.When the time comes to work on any of the said parts you will be so much happier that nothing stripped,snapped,rounded off,etc.Just my 2 cents worth.
