Ok i was thinking about a car that i got in a trade years ago.Saab 900 turbo(1987) had been sitting around for a couple years and had a bad fuel pump, along with a congealed mess that was the pump pickup tube. cleaned the gas tank replaced pump and pick up tube, fired up but sputtered and quit. found return line plugged. with fuel line replaced got excited and stared it up in the garage and damn near burnt the house down. i forgot to tighten it!!! two fire extinguishers later found the problem along with all injector lines melted.....scrap!
