Well, a little background. I picked up a 1990 base model XJ (4.0 L auto) yesterday. I got a good deal on it ($1100) and I think the only thing it needs to get running fine is to clear out the old fuel that has been in there (1/2 tank) for the better part of a full year!
Now, for the questions:
1. Is this fuel system under pressure, or can I just pop off the fuel filter with no repercussions?
2. It was suggested that I use the fuel pump to pump out the old fuel rather than just syphon it. To do this, do I simply unhook the fuel line at the fuel filter and let it shoot into a 5 gallon bucket? How do I get the fuel pump to run? Do I need to just try to turn the truck over, or just keep flipping the key to the aux setting?
3. It was also suggested to me that unless I KNOW the fuel pump is bad, to just let it be. If the pump is still good, I drain the tank, replace the fuel filter, put some fuel system cleaner in it, and fill the tank with clean fuel, I should be good to go after a few minutes of flushing the old stuff out of the lines, correct?
If there is a write up or I am missing something with this procedure, please speak up. The fuel system isn't really something to experiment with and I would prefer not to burn down my garage.
Thanks in advance for the advise.
