John, I am new to MGB ownership and regularly check out your videos. They are very helpful especially this one for the fuel sensor. I am happy to report my gauge is now fairly accurate after following your video fix. Thank you
Hi. Great video! Love the deep explanation about inside that box. Didn't understood very well ( not my main language) but the thin wire could be replace with other thin wire? Why I need to keep the old one their?
Good video, thanks. The sending unit on my '74 B was so gunked up, I replaced it. Prior owner had allowed old gas in the tank. I eventually was able to clean up the bad gas and the car runs nicely now.
I repaired a "closed cell foam" float by drilling a hole in it just large enough for an automotive marker lamp (baseless bulb about 1/2" OD) Buoyancy regained and gage works great again. Drill hole slightly undersized for a tight press fit of the bulb glass into the foam.
Am going to try on my nissan atlas truck 🚚 hope that fix my problem. Because my gauge do work but sometimes it say half or empty then it work again then do same thing again and again 😢 i would like to see it work great 😅
My gauge only swings between 1/4 (empty) and 3/4 (full.) Clearly not a float problem and I find it strange that, if a calibration problem, it is at both ends of the range equally.
Also I wish I had seen a video like this several years ago when my sending unit failed. The new units are not consistent as I get a different reading each time my gauge starts to hit the red. (1977) Sometimes I need 1.5 gallons and other times I need 2 or more. I try to rely on the trip odometer but that sometime is finicky, possibly due to age.
