They are all from difference dealers. This fuel pump from australia is about $850 will go see them tomorrow and get it swapped outIs there anything that could be causing the pumps to fail??

Looking at the intake, what do the vanes look like? They should be a gerotor type (same as our oil pump gears) and not fan type. Can you take a pic?

I can still drive it except it has abit of a miss at 1800rpm and it leans out on boost. I'll let you know how I get on.. Link to comment Share on other sites More sharing options...

If its blocked it would be creating a vacumn and making the pump be unable to suck fuel?? Link to comment Share on other sites More sharing options...

New fuel pump is in slight misfire at 1800rpm has gone and its running abit smoother on causual driving. BUT on WOT its missing and definately not making 310kw. We checked for fault codes, Checked spark plugs (all 6 brand new NGKs) Checked coils no issues there. Anyone got any ideas where to from here?? :censored: Link to comment Share on other sites More sharing options...

Someone else might be able to shed some light on it. Link to comment Share on other sites More sharing options...
