Dave connors Posted March 8, 2021 Share Posted March 8, 2021 I've had to get a replacement fuel gauge for my 2011 fuel gauge as the original fell to pieces although it still worked, the new one reads a lot lower than the original one they look identical apart from the suppliers number on the back, anyone now if the replacement is correct, old one is shown on the left.

John Vine Posted March 8, 2021 Share Posted March 8, 2021 I can only guess it's to do with Caerbont's own calibration, maybe for different models or model-years. Can anyone advise on the significance of the -69B and -75B suffixes?What model/year is your car, and who supplied the gauge?If no-one can help, I think your best bet would be to ask Caerbont themselves, quoting your two numbers.Do let us know what you find out!JV Link to comment Share on other sites More sharing options...
John Vine Posted March 8, 2021 Share Posted March 8, 2021 Just a thought...Looking at your photo, it looks as though your old gauge has cracked round the rim, just under the bezel. That's exactly what happened to mine some years ago (probably due to over-tightening the clamp), and I succeeded in repairing it (with either Araldite or superglue, I think).JV Link to comment Share on other sites More sharing options...
John Vine Posted March 8, 2021 Share Posted March 8, 2021 This was mine before the repair:JV Link to comment Share on other sites More sharing options...
Garth Posted March 8, 2021 Share Posted March 8, 2021 Also repaired mine with 'superglue' ages ago! Still fine! Although going to change one day!! Link to comment Share on other sites More sharing options...
John Vine Posted March 8, 2021 Share Posted March 8, 2021 A little more info...According to CC parts website, -69B is the 1/4-sweep with black dial and chunky (non-italic) logo (P/N 71250):The previous version (1998-2000) looks to be -59B.And -78B says R400, although the label says CSR.I can't find -75B anywhere.JV Link to comment Share on other sites More sharing options...
R300 FNL Posted March 8, 2021 Share Posted March 8, 2021 I went from a 2003 to 2020 fuel gauge and the calibration was different with both gauges so caerbont had to recalibrate the new one. Maybe worth giving them a call. I wanted to change the bezel out at it is scratched, has anyone tried to remove the bezel & glass? Link to comment Share on other sites More sharing options...
Dave connors Posted March 8, 2021 Author Share Posted March 8, 2021 I've contacted caerbont so ill wait and see what they have to say Link to comment Share on other sites More sharing options...
Dave connors Posted March 9, 2021 Author Share Posted March 9, 2021 Had a reply from Caebont it might mean something to someone hereEFC1-1152-75B needs a sender that is 109 ohms empty & 4 ohms full, this may be a Caterham special as we don’t list one for those values EFC1-1152-69B needs a sender that is 240 ohms empty & 22 full, non linear end to end.

John Vine Posted March 9, 2021 Share Posted March 9, 2021 Very speedy response from Caerbont! You now have your answer.The sender resistances for -69B are in line with the Ford Sigma/Duratec fuel pump fitted up to around 2015. On my 2008 R400D, these came out as 209 ohms Empty, 24 ohms Full.A sender resistance of, say, 100 ohms on your old -69B gauge (about 1/2 full) would give a much lower reading (approaching empty) on your -75B replacement.It looks as though your new gauge is the wrong one for your car. Can you return it for a refund? Who supplied it? And rather than chase down the correct gauge, it would probably be simpler to repair the old one.ETA: An alternative might be to send the -75B to Caerbont for recalibration.JV Link to comment Share on other sites More sharing options...
