Changing the fuel filter It seems to be a fairly simple task, since I can see the filter underneath. I'm a bit confused by my manual though and want to confirm. 1)Disconnect the negative battery cable 2)Loosen the filler cap 3)Connect a fuel pressure gauge to the fuel pressure tap. Wrap a shop towel around the fitting while connecting the gauge to avoid spilling fuel 4)Connect a bleed hose to the gauge and insert the other end into a suitable container for storing fuel 5)Open the valve to bleed the system Disconnect the fuel lines Remove the fuel filter from the mounting bolt. My burb is a '98. I didn't think I needed a fuel pressure gauge to do this maintenance?
