Is there a certain fuse I can pull out to disable the fuel pump whilst I change the fuel filter? I don't really want to disconnect the battery incase the brant goes stupid..

Cheers

no need to take a fuse out, i never do. Maybe a good idea to take fuel cap off to release any excess pressure (although i never do that either).

You need to de pressurize the fuel system. To do this I disconnect the electrical conection at the fuel pump and crank the motor a few times.

Ok cool thanks I won't bother disconnecting anything then.. I was planning on cracking the fuel cap just to be on the safe side..

Question. When the car is not running, do the fuel lines still hold anywhere near the pressure they have when the car is on? Just trying to work out if I'm going to get sprayed with fuel when I pull the fuel lines off the filter or will it just dribble out?

cheers

The fuel pump has a built in non-return valve in it to preserve some fuel pressure when the engine is off. The valve stops fuel in the lines spilling back into the tank. Having pressure in the line while the engine is off makes it easier when you go to start the engine again. Without a non-return valve, you would need to prime the pump every time you start the car, and that would be a pain in the ass.

Opening the cap will not release the pressure in the fuel lines.

obviously not the pressure when the car is on i am sure it would loose some. You could get sprayed a little bit if your unlucky just put a cloth over it when you pull the hoses off and you shoudl be ok. Those hoses will probalby be tight too so may need to give them a bit of a twist.

Ok, so disconnecting the fuel pump and then cranking the car will depressurise the fuel lines yeah? Do I need to disconnect the CAS so the car won't actually fire up, as I would assume that would be a bad thing if it then runs out of fuel in the lines...

cheers

what you actually do is whilst the car is running disconnect the white plug that runs to the fuel pump and that will disconnect all the power running to the fuel pump and also depressurize.... you will find that u will pull the white plug and the car will stay on for a further couple seconds and then conk out... thats the way to do it

When removing a fuel pump, your supposed to disconnect the fuel pump relay, then crank the engine to remove any residual line pressure.

This is located on the left side of the front passenger foot well.

If you dont do this, fuel will piss out when you disconnect the lines from the fuel pump mount.

Sweet thanks guys, will disconnect the fuel pump and run the car till it conks out.. should have no probs then..

cheers
