Look under vehicle foolow the fuel line from the tank

It's part of the fuel pump assembly located inside the gas tank.
On a car, 40 liters.
The pilot-operator of the Cessna 40l which fatally crashed.
I'd vote for the injectors. Try a professional fuel injection cleaning. Occasionally run it up to 3500 rpm for 30 seconds in low gear to keep breaking up the carbon deposits.
No door. You have to drop the tank.
Get a Haynes or Chiltons manual from an auto parts store and don't forget to label everything.
It is located underneath the hood. You might have to clean it off with a rag to read it.
My mechanic says 100:1 I have done this for 40l last season without a problem
the 4.0l s.o.h.c. enging has a timing chain tensioner kit. wich is suposed to fix the slight ping on start up. check with your locad dealer with your VIN # and have them check to see if you have any RECALLS on that issue.. ie only fix if the prob is thier..
The belt tensioner is located at the bottom of the power steering pump looking at it from the front the tensioner is on the bottom left. you could always loosen the alternator up a little. My 1997 with a 4.0 does not have a tensioner pulley, and I believe the 99s are the same. the alternator is the tensioner. Remove one of the bolts and it will swivel in and you can get the belt off
