Where is the fuel relay located under the hood in a 2003 VW Jetta 1.8T?

It is on the passenger side right behind the washer fluid fill tube. You can follow the fuel lines (look like 1/4" black tubes, some are clear) from the injector pump to it. It is a caniser a bit bigger than a normal looking oil filter and sits between the washer bottle and the metal that forms the wheel well. It is held in by a screw type clamp about half way down the cylinder. Probably isn't the fuel filter unless there is air in the lines to the injector pump or they didn't bother to fill the fuel filter up with diesel after putting it in. There is not a fuel pump in the tank in these cars so everything is sucked up by the injector pump and it needs to be primed properly.

JUST RELEASE THE PRESSURE AT THE FUEL PRESSURE TEST PORT ON THE FUEL SUPPLY RAIL THAT SUPPLIES THE INJECTORS, IT IS A METAL VALVE LIKE A TIRE VALVE, THAT IS THE FACTORY RECOMMENDED METHOD..

It’s located on the driver’s side of the engine on top /side of the head.. midway.. I don’t think you need to remove the engine cover to see it.. if it is the correct one it will have a dark green top.. the bad version has a black top… but they can all go out to lunch on you if old enough.

To replace.. make sure the car is cool..
You need a hood tool.. or small pair of pliers to remove the retaining clip that holds it in place.
Place a rag under and around it to catch the coolant.. you will lose less than a half a cup.. if that.

Pull the retaining clip back toward you.. try not to drop it.. (another good reason for the rag)

Wiggle the sensor.. pop it out.. and replace with the new green top one make sure you clean the area well.. and when you reinstall the new one that the c clip goes back on straight or it will leak.

Once you see the part out of the box.. you will understand how it works

Start the car.. check for leaks.. run until warm with the heater on.. top up the coolant overflow bottle with distilled water.. (if more than a half a cup.. you should mix the proper anti freeze and distilled water and then top up with that)

Good luck
