Have you got any idea how your swirl pot is constructed inside Olli? Do they provide a diagram or anything?________________________________________

quote: The three upper connections are -6JIC and the lower connection (to high pressure pump) is -10JIC. that's all I've found, and really unless there's a blockage on the return to the tank that's all that could cause this, specifically as a test to just get the engine running it doesn't matter which way the smaller pipes are connected at all, you just wont get all the air out if the return to the tank isn't fed from the highest port. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Pretty much all I found out, we definitely checked the return to tank as I remember using my girlfriends coffee mug to collect the fuel in... She wasn't to happy |

I'm also trying to find out why the 044 allows fuel to flow when it's de-energized, I'm guessing it does allow fuel to flow either way so then it can release the pressure in the line when the car is off |

A lot of swirl pots have a restrictor in the return to the tank, I assume it is to keep the swirl pot slightly pressurised to keep it full and stop the fuel sloshing about, they aren't usually baffled or anything inside. If that is the case you will get some flow, as the injectors open the pressure will drop on the flow to the fuel rail and you'll get enough fuel to give it an idle. Some pumps have non return valves in them but they don't have anything in to stop fuel flowing through them when they aren't operational. Was wondering if it didn't happen on Rich's tank because they sit that bit lower and also the flow is picked up from the bottom of the tank so there will be some restriction there. Your's won't be far off level with the fuel rail so you won't need much pressure to generate some flow. ________________________________________ Oulton Park in a BTCC 306 vid 1Oulton Park in a BTCC 306 vid 2 Lap of the 'ring |

afaik the 044 will have a normal non return valve on its outlet, this only works one way.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I think i removed the non return valve if it's the bit I'm thinking of, when I got the pump from think automotive it came with a fitting on the out let for a banjo fitting but it was around an 1" long so I guess the nrv was part of that |

Nope, I don't have one yet... I'm pretty sure it's an electrical fault and the fuel system is not to blame, weather it be something shorting out or the alternator not charging the battery so when the hp pump is connected it draws to much power and takes it away from the ecu etc |

My 2 high boosts ran 044's and so did this before but I had a new one so sold the old one! Its not the pump as it primed and runs fine before the engine starts! I'm using a different regulator because iv got the bigger charger |

I can't see the battery being an issue, if it starts the car the alternator "should" do the rest! I'm not running a heated rear screen, electric windows etc just the bare minimum |

I will do but I'm starting to think alternator, hope it is the battery as changing the alternator will be a right pain in the arse |

But if there is a current demand the battery will back up the alternator. Uve already let the battery go flat which isnt advised with a race battery________________________________________ |

Well it didn't go dead hence I stopped and waited for it to fully charge! That's what I mean if the alternator isn't charging the battery or working as it should its relying on purely the battery power |
