hi,thinking of changing the fuel filter on my audi a4 avant estate 2011 tdi cja engine ?.ive looked on youtube but concerned about pumping fuel through with a hand pump.....i bought and used this one (see pic) on my old volvo v40 and it worked ok....i have no problem removing the fuel filter.its the pumping fuel through side.can i use the one in the pic.....has anyone done this job without using diagnostics to pump it through as i dont have one.i know the fuel pump can damage your pump then engine if not done right.i have not rung a garage as i want to save money.but if people think its best to use a garage then fair enough i will leave it.i have the car on ramps at the moment.if i do go ahead i will post pics thanks all

update no need to pump the fuel through😉with the handbrake on and in first gear jack the car up on the drivers side where the 2 jacking points are then put 2 axle stands underneath and remove both the small and the large cover most are 10ml and are them funny plastic plugs which can easily break.theres a couple of plug ones where you have to remove the central plug before removing the outer plug.there is also i think a couple of 10ml nuts too....note where all you remove come from.then remove the bracket that keeps the fuel filter from dropping down.held on by 1 10ml nut.then carefully squeese the back bracket of the filter and move it away from the filter and do the same with the front bracket i then placed a bowl underneath  and removed the front pipe from the filter and lifted it upwards to keep as much fuel as possible in place and stuck it between the 2 brake pipes.and did the same with the pipe at the back of the filter.and then tipped the fuel from the old filter into the bowl and then removed the 2 covers from the old filter and put them on the new one(Audi dealer only supplied the bare unit (£35)as they now sell the 2 coverings seperately).....note in my picture the arrow on the filter is pointing towards the front of the car when fitting.i carefully put the back pipe on to the fuel filter and put the clip back in place and same with the front pipe been carefully not to spill much fuel(to make it easier to start the car)....it is a bit tight putting the front clip up to the filter,after doing the back one....then put everything back in reverse order.pics 17/18/19 shows what its like underneath without the plastic covers on.pic 20 shows what can happen over unscrewing the plastic nuts.last pic i was told to remove the pipe and attach a clear pipe to it with a hand pump a bit like mine until the fuel comes through.....please look at steve Q's tip on priming the pump first

Hi easiest way to prime the filter is sit in car turn the ignition on and off six or seven times without starting the engine [no clutch depressed] and the lift pump will prime it for you, only run the ignition on for ten seconds at time.
