Hi Zouritte,
The following worked on my 2.2, it is NOT the recommended method, which is to bleed the fuel pipe at the top of the engine using a special tool. At the top of the filter housing, disconnect the fuel pipe return to the fuel tank, it has a blue push-in connection which lets you pull the pipe off. Put a piece of hose on the now exposed pipe on top of the filter housing and aim it into a container to collect the returning fuel (or just have a mess on the floor). Turn ignition on just enough to get the pump running, you will be able to hear it. This will push some fuel around the system but the pump only runs for a short while until switiching itself off. Then switch off iginition switch and repeat process a few times until the returning fuel seems to be clear of air. Reconnect the fuel tank return pipe to the top of the filter housing. Cross your fingers and try starting the car. Good luck.  2.2 90 XS

Unfortunately the above won't work on a 2.4 since the combined low/high pressure pump is a mechanical unit on the engine, and (unlike the Td5 and 2.2 TDCi) there's no pump in the tank.
You have two choices really. One is to use a bleeding tool, either the incredibly expensive proper one or a cheaper substitute, to bleed the system. The tool is a squeezy bulb you connect in the fuel line adjacent to the pump and squeeze repeatedly until bubble-free fuel emerges. Your other choice is to open the bleed valve on the fuel line adjacent to the inlet manifold and then pressurize the tank to force fuel through (or disconnect the quick connector where the priming tool is connected then pressurize the tank). Probably the easiest way to pressurize the tank is to extend the breather pipe adjacent to the rear o/s wheel and either blow, or use an airline etc. I fitted a pipe with a Schrader valve when I had to do this so I could use a footpump. If you over-pressure the tank a relief valve in the filler cap will open. |

The simplest way to bleed the system is to remove the fuel cap, get someone to hold a rag over the filler neck with an air line inside. The tank can be safely pressurised whilst cranking the engine over, it will still take a while to get the fuel up to the fuel rail before it starts. It is a terrible idea, god knows what you would do if you ran out of fuel in the middle of no where !!!!

Thanks guys,
I've noticed that in the engine bay, coming from the filter there is a pipe going to the pump, on that pipe, there's a cap i can unscrew, i'll try to suck from here using an extension pipe, to have the fuel coming all the way till there. Otherwise i'll try blackwolf or Skeggy 90 's technique. I'll keep you posted tomorrow. Cheers Tim |

I just put some pressure in the tank with a hose/rag. Do not forget to open the bleed valve. Puma 110" SW

hi,
Done worse today  as the previous owner when in the desert, there is tiny bits of sand everywhere on the truck, i tried to unclip those pipe around the filter and the sand was blocking the full retraction of one clip, so i broke one tits of the fuel filter lines.... So i decided to stop the mess, ordered a new filter "older" and the lines to be sure no sand has gone anywhere. I'll manufacture the feeding tool with the remaining lines and the manual pump (Sealey - Ebay).
Good lesson though.... alway refill this filter before firing up the engine.... Thanks for your help Tim |

tread VERY carefully.
I did mine and it possibly contributed to the demise of my high pressure (common rail) fuel pump. Drove me crazy since every other car I've ever done either has a manual pump on the filter to prime it, or has a lift pump which you can set going (some combination of peddle presses on a td5 i believe to set it priming) spoke to the mechanic at the local LR dealer and he says its the worst fuel system design for this that he's ever seen. For use it on a lot of their cars apparently and it causes quite a lot of issues. sure you'll sort it though, i had other problems with my fuel pump too (dirt in fuel from bad delivery) which i think meant that the pump couldn't get enough fuel and it eventually gave up.

I did mine a couple of months back but got a good tip off someone
With the IGN on push the Accelerator pedal 5 time it puts the pump into a perge mode and will not switch of any air in the system should get cleared, The closer you are to death the more alive you feel |

It's a Td5 thing. The 2.4 Puma doesn't have an electric pump.
The 2.2 Puma however has gone back to a pump in the tank, probably to avoid all these bleeding problems, but I don't know if the pedal trick works on this. Be aware that on the 2.4 the volume control valve (VCV) in the pump is very easily damaged by water, dirt, or air in the fuel and will cause major drivability issues with no DTCs. |

Sorry for the topic hijack... but Done the same last saturday!
Ended up pushing the 110 down the street and it then turned on at the second try! Working fine these days! However everyday in the morning, on first startup, imediately after turning it on it looks like it's going to turn off for half a second, but then continues running! Then it works fine during the day.... Any ideas ? Is it from the fuel system? Or it's a coincidence? Do I have to bleed the system?

Check for DTCs, especially P268A and/or P268B. If present recalibrate the fuel pump.
