Mark Posted September 9, 2007 Share Posted September 9, 2007 HI All How easy would it be to put a fuel gauge in my Jimmy, it currently does not have one except a marked stick?. It is 12 volt as well was this normal or were they 24 volt originally. Thanks Quote Link to comment Share on other sites More sharing options...
Tony B Posted September 9, 2007 Share Posted September 9, 2007 Is there a way of putting a float into the tank? You could use something like a Land rover unit. the problem will be the length of the float arm. you may not get accuracy but at least it would mark the embarrassment level. As yours is 12 volt there are plenty of candidates. Wiring is easy earth, tank unit, gauge power. A hole can be cut in the tank with a pipe cutter drill. WARNING- Any drilling on fuel tanks, empty and inert tank first, one way of inerting is to take the exhaust gas from another engine and feed it into the tank. Another way is a co2 extinguisher fired into the tank. PS do any of this outdoors. Quote Link to comment Share on other sites More sharing options...

Mark Posted September 10, 2007 Author Share Posted September 10, 2007 Jack I have a blanking plate where the gauge was and I have not looked to see if there was a sending unit in the tank. Were they 24 volt orignally Quote Link to comment Share on other sites More sharing options...
Degsy Posted September 10, 2007 Share Posted September 10, 2007 No Mark, they were 6 volt. Quote Link to comment Share on other sites More sharing options...
Mark Posted September 10, 2007 Author Share Posted September 10, 2007 OK thanks for that , it is going to be a problem then to get a 12v sender unit and gauge then?? Quote Link to comment Share on other sites More sharing options...
TooTallMike Posted September 10, 2007 Share Posted September 10, 2007 OK thanks for that , it is going to be a problem then to get a 12v sender unit and gauge then?? Mark, I've got several 12V gauges FS but frankly I wouldn't bother except as dash ornaments. WW2 era truck fuel gauges were/are cr@p (in my experience). The stick will be much more reliable :-D Quote Link to comment Share on other sites More sharing options...

Tony B Posted September 10, 2007 Share Posted September 10, 2007 If you truly want a gauge. Have a look at the kit car market. Wouldn't be period though. Quote Link to comment Share on other sites More sharing options...
Jack Posted September 10, 2007 Share Posted September 10, 2007 OK thanks for that , it is going to be a problem then to get a 12v sender unit and gauge then?? Hi Mark. I would go for one if you can as mine was pretty spot on. You can use a 6v unit (like mine) but you will have to put a reduce in the sender line ( think that is the right term/product/gadget but Degsy or others are best place to confirm that). I have yet to do mine :oops: Quote Link to comment Share on other sites More sharing options...
Joris Posted September 11, 2007 Share Posted September 11, 2007 I have a fuel gauge that gives you an idea of the fuel level but will never be reliable. Most of the WWII fuel gages I see are like this, it's very tricky to get it to work properly. Quote Link to comment Share on other sites More sharing options...
shopnut Posted September 11, 2007 Share Posted September 11, 2007 Hi Important to remember on 6 volt fuel gauge, is to have a good earth, I always have a earth wire on the sender back to the frame, and ensure a good earth on the gauge to the dash. Found it worked well. Quote Link to comment Share on other sites More sharing options...

I have yet to do mine :oops: The item your referring to Jack is a voltage regulator a LM7806 is one type available from most electrical components suppliers . It reduces the voltage to 6v from 12v at 1amp (if your running a 12v system)as the sender unit and gauge's were designed to run on a 6 volts system. I've never had a gauge work correctly ,it's got a lot to do with the way the gauges were wired during manufacture.I'm going to do some experiments using a modern day 12v smiths gauge wired to the GMC sender unit to see if i can calibrate it using resistors to get the right deflection on the gauge ,I'll let you know how i get on regards Steve Quote Link to comment Share on other sites More sharing options...

Steve Great advice Steve - I will get one sorted as I haven't had a gauge since I went over to 12 volt (still the best thing that I have done).

Marmite!! Posted September 11, 2007 Share Posted September 11, 2007 Couple of options... http://www.avnet.co.uk/lts/pages/fuelgauge.htm or an in-tank mechanical gauge.. half way down page.. http://www.dieselveg.com/fuel_tanks.htm Quote Link to comment Share on other sites More sharing options...

N.O.S. Posted September 11, 2007 Share Posted September 11, 2007 Hi Mark Jeeparts now do an excellent 12v repro gauge. You can use this with the original sender unit (this is just a variable resistor). If you want to use a 6v gauge, the voltage reducers are under a quid from Maplins or similar.
