Newbie fuel gauge help
Right, Iv bought my zt 2.5 v6 off a member on here, the fuel gauge seems to read what it likes, some times it reads near full then next time I get in it, it reads under half. Now he mentioned somthing about a orange clip on a recall. Is their any one on here who's got a idiots guide on how to check for the fault. I'm good with machanical bits but no good with electrical.
I'm located in Derbyshire/Nottinghamshire if anyone is local who knows what their doing Sorry if this has been discussed before |

Best you can do is search yourself in the search toolbar. The orange (or white) clip has nothing to do with the fuel gauge, it's a recommended fix to prevent the fuel filter unscrewing on later model cars. Again try the search. You could do much worse than attend one of these meets: http://www.midlandsnanomeets.co.uk/meets_2014.html where there are a host of knowledgeable guys who can fix just about anything. Regards |

I think the orange clip referred to is to prevent fuel filter separation (FFS) aka the Fabled Orange Clip or FOC -in later petrol cars the fuel filter can come apart leading to non starting - the solution is to bind the filter with a clip ( originally orange).
So your issue re the gauge reading is not linked to the clip - it sounds like there is a fault in the fuel tank sensors/floats.

Here's the MGR Technical Tip covering the issue: http://www.mediafire.com/file/dwu9ob...%2529.pdf/file The filter is inside the fuel tank on the LHS. To access thia you have to lift the rear seat cushion. This in itseft can be a chore, but there are helpful tips. You'll find some in Post 3 here: https://www.the75andztclub.co.uk/for....php?p=2531165 There's a screw-down hatch in the floor that gives access to the filter module. Info on getting the module out and most importantly, refitting it correctly is given here: https://www.the75andztclub.co.uk/for...ad.php?t=58832 and here: https://the75andztclub.co.uk/forum/s...ead.php?t=9108 TC Last edited by T-Cut; 1st March 2020 at 09:20.. |

There's a level float in both sides of the tank. One on the pump module (RHS) and one on the filter module (LHS). They each send a level signal to the ECU which integrates them into a tank content signal for the fuel gauge. A common cause of faulty readings is through work being done in the tank (like replacing the fuel pump). This sometimes causes the float arm to be installed incorrectly so it binds/sticks.
You may get a clue as to which float unit is faulty by running the IPK diagnostic mode. sEE link below for instructions to run the vehicle diagnostics. https://www.the75andztclub.co.uk/for...iagnostic+mode

More on tank diagnostics. This is a copy/paste of my standard response:
The tank is divided by a central ridge and fuel is drawn from the drivers side by the pump module. The high pressure fuel flow is divided and operates two venturi (static) pumps within the tank, which distribute the contents to ensure the supply to the pump inlet is maintained at all times. There is a float level sender in both sides of the tank - one on the pump module and one on the filter unit. The gauge integrates their signls to display the net contents. Erratic gauge output may be due to erratic floats. If one or both has been disturbed when the pump and/or filter module has been serviced, it is difficult to get the floats repositioned right. This may cause binding in certain positions. The floats operate a rheostat with a linear resistance value against float level. You can check the float resistances using an ohm meter. There's a connector socket under the rear seat, driver's side. This diagram may help. TC |

Right Iv done the diagnostic check on the dash and it came up as 6.2 ___0229
So I'm assuming it means the n/s float has a fault |
