GBMUD Posted December 4, 2015 Share Posted December 4, 2015 Are there any baffles in a Td5 90 plastic rear fuel tank? New Siemens/VDO fuel pump/sender fitted the other week and now the fuel gauge is a work of fiction - reading empty when it is not, not reading full when it is, rising during a journey etc., any suggestions? AFAIK there is nothing in the tank to get the float caught on. After driving for 29 miles with the fuel light on last weekend I only managed to get 39 litres in till the tank was brimming.

Mo Murphy Posted December 4, 2015 Share Posted December 4, 2015 I don't think so Chris. It sounds like your float isn't floating, perhaps it's punctured. Unfortunately the only way to find out is to drop the tank again. Mo Quote Link to comment Share on other sites More sharing options...
Les Brock Posted December 4, 2015 Share Posted December 4, 2015 Seem to remember Chris it needs to go in a certain way as the arm catches on the side of the tank or sumfink, been a while since I did mine Quote Link to comment Share on other sites More sharing options...
Boydie Posted December 4, 2015 Share Posted December 4, 2015 No, no baffles, the fuel just drops to the lowest point which is the pick-up point Quote Link to comment Share on other sites More sharing options...
GBMUD Posted December 7, 2015 Author Share Posted December 7, 2015 Thanks chaps. Much more likely to be a duff sensor than the float jammed up on something then. IIRC from doing the sensor in my 110 years ago, there is just one plug serving both sensor and pump? Chris Quote Link to comment Share on other sites More sharing options...
GBMUD Posted December 16, 2015 Author Share Posted December 16, 2015 The problem turned out to be rather simple. The sender had become detached from the pump/swirl pot during installation and was hanging on it's wires ion the tank. It has now been refitted and seems to work correctly. Gladly, the mechanic who fitted it for me took it on the chin and did it all FOC. Chris Quote Link to comment Share on other sites More sharing options...
mickeyw Posted December 16, 2015 Share Posted December 16, 2015 Gladly, the mechanic who fitted it for me took it on the chin and did it all FOC. Chris As I would expect a good mechanic to do Chris. Alas there seem to be rather too many fly-by-night types with no interest in nurturing good customer relations. Glad you are sorted and that the problem was an easy one.
