hi mate, having not tackled this yet i am not shore but have sugestions.are you filling the filter with fuel to the top? i beleve you have to blead between the filter and the injectors as well. when you have done this you need to run the nmotor at 2500 rpm for 5 mins or so (i am told) any air anywhere will make it cut out. some one will be along to help soon. they will sort you out mate |

Is it the right filter, has it sealed properly? there's always the cheats way.... fill the filter to the top and refit buy some easy start get someone to flick the key then give it a squirt as per instructions on the tin!!! it's a rough way of doing it and i only use it as an all else has failed kinda back up should get it going though, then run it at fast idle (2000 rpm ish) for about 5 mins _________________ landcruiser 80 series 4.5, 35's/33's for road, 2inch lift, discreet winch, sliders/armour, factory lockers, stainless side exit +++++ |

Sound's like your new filter is'nt sealing properly, Have you checked the water trap plug (on the bottom of the filter) check seal and make sure it's screwed in fully.
Is the prime pump on top of the filter working (mine dosent ) if unsure remove outlet pipe of fuel filter then prime, no fuel then your prime pump could be knackerd.
I cheated when i blead mine, (as i needed the car too) i increased the air pressure CAREFULLY inside the tank with a compressor air line in the filler cap with a rag round it to seal it this forced the fuel through filter with outlet pipe on filter disconnected _________________ 2011 3.0l Hilux Invincible

If the primer pump is knackered, screwfix do one fro £9.99 for diesels. Fitted one to a frontie a few weeks ago and work fine... _________________ For great insurance deals on 4x4s, imports and more, contact Adrian Flux :

undo the 12mm bolt on the rear of the injection pump, between the fuel outputs to the injectors. Then turn on the ignition and prime the fuel pump, youll get diesel spewing out but it will ensure the pump isnt airlocked too. |

crack the nut slightly on the first injector turn it over and see if fuel comes through,it will run rough for a few minutes,then tighten up. _________________ Mickyboy

Well thank you soooooooo much for all your kind response I have finally managed to sort this head rush problem.
I put the new filter pump on and found it was the same change the inline pipe and BINGO i cant really understand
why changing a fuel filter would damage the rubber fuel line is beyond me but all i can say is thanks again keep up the
suggestions coppo |
