This unit is a complete drop in item that will require no modification, it is a brand new cartridge with a Walbro 400 litre a hour pump installed (not Chinese copy of a walbro pump like many others). If you are looking to make good power then this is a must. This pump has been dyno tested to 500 rwks. as you can see in the pics, it is available for sedan and ute, the ute comes with the sender and the sedan does not. 00028206
