Priming the fuel pump

taylorslandy72 · Mar 14, 2015

Hi, just replaced the fuel filter on my s3 can't for the life of me get the landy to fire up, is it just a matter of pumping the small lever below or am I doing it all wrong

if its diesel you need to undo the bleed screw on pump body 8mm spanner and pump lever till filters full and clean fuel no air comes from bleed screw

Thanks buddy, just done a search and spot on to what you said. Thanks for your help, 1st service in years oil like black sludge, filter clogged with god know what should notice a difference

Remember that sometimes it is necessary to turn the engine over half a turn when priming to ensure the lever moves on the back of the cam. I have helped people that have pumped the lever for hours and not got any fuel to lift !!

The filter needs bleeding first...then there are 2 bleed screw on the main pump body.

Thanks all, nothing came through bleed screw so I attached jump leads to my transit which turned the landy over fast, it fired straight up so all good

In that case...the cam may have been in the full lift position...not letting the pump lever do its job.
