When I was younger there were very few problems on any of my cars that couldn't be fixed under a tree providing shade and a small box of tools.
Now days some of the modern cars have the fuel filter integral to the fuel pump which is then hidden inside the fuel tank.
Saves a little cost when making the car. Sure sucks the wallet dry when it needs replacement.
On some of the internet auto repair chat sites the first question is, "what codes are you getting?"
I remember the simpler times when it was either compression, ignition or fuel.
Now there are more little "black boxes" just in the engine area than it took to build some of the cars I used to drive.
My old vehicles had clear fuel filters or a glass bowl with a replaceable element inside, easy peasy.
Our current car took me awhile just to find where the filter was hidden. Relieving the pressure from the system was another added feature. Still after getting the car off the ground with the pressure released there was still plenty of fuel in the lines to spray and drip with a rag held around the fittings as it was replaced.
Rube Goldberg was a prophet and deity to modern car manufacturing.
