In Tank Fuel Pump Replacement

A heads up for anyone doing this job, car still ran (tandem pump able to compensate) but no sound from the pump priming when key was turned. My car 2005 1.9 Tdi AVF access was through a panel in the boot floor, made easier by folding the rear seat if you have this option. A lot of dust and dirt had accumulated on top of the pump so be prepared to vacuum this clean before you release the retaining ring.

There are supply and return fuel lines with quick connectors and these are marked on the top of the pump, have plenty of rags to keep things clean. The retaining ring can be released without a special tool but obviously it is preferable to have the correct tool. I replaced with a VDO pump which comes as a complete assembly with pump and level sensor and is a direct replacement for the original factory fitment which was also VDO. This doesn't come with the seal so I reused the old one but probably better to replace that too, mark the orientation before you remove and replace in the same position. Be careful when putting it in that the level sensor does not get damaged, may require manoeuvring to work it into the correct position. Make sure the tank has 1/4 or less fuel in it and reconnect the lines and electrical connector, 3 screws holding the access cover and you are good to go. Mine lasted 14 plus years and 376,000 km so they are reliable, of course fuel quality and operating conditions will have a bearing on this.
