Help with Unidentified Fuel Gauge

[Simon Mc]

This is my 1st post so please excuse me if I get something wrong.

I am not from a military background but through a house clearance I have two Fuel Gauges, which I believe are from a british military vehicle.

I would be grateful if anyone could identify which vehicle the following fuel gauge was fitted to.

I made enquiries with the REME Museum at MOD Lyneham and they identified it as british but could not place which vehicle it come from or shed much light on it's age..

It has the following numbers stamped on it. 

FV 494553  S.M.CODE AV4   No: 2     Mk. 2   And on the face : TS9941

It has both 'G' and 'D' stamped at the full mark. Which I'm told are marks for 'G' Gasoline and 'D' Diesel. So the vehicle it was fitted to could have had ether engine.

Also, it has no bulb fitted for lighting up at night. It has cut outs just below the top screw on ring to let light through the sides to the face. For 'Convoy Mode' ?

Any ideas anyone?

I wonder if the sender part of this fuel gauge measured the weight of the fuel hence the difference at the full mark. I have come across gauges such as this before in airfield crash tenders for the water tanks. So was it for a multifuel engine perhaps.

Thanks Richard for your reply.

I think you must be right about it measuring the weight of the fuel. It's my understanding that diesel is heavier then petrol so that would account for the differing 'D' and 'G' marks.

But why would a vehicle require this type of gauge and not just a normal float level gauge ?

I suppose this design would be more accurate/reliable in a vehicle used over rough terrain ?

The guys at REME thought that it come from a Army vehicle that could have been ordered or specified with ether fueled engine, but couldn't think of any to name at the time.

Maybe others on the forum can think of some.

Strange that the gauge reading is only G & D at full, which really limits the accuracy when the tank is only partially full. 

In the first photo, are they 2 pipes rather than wires going into the gauge?

I think Richard may be correct with multifuel in which case I'd be looking at vehicles with a K60 engine such as 432 or Abbott  but I'm only guessing, there are members on here who have these vehicles so they should be able to help.

It could possibly be for an Austin K9 Series 3, they were multi fuel but were not taken in to full service only a small quantity were used. If it was used in K60 engined vehicles surely someone on this forum would recognise it.

Definitely not from an FV430 of any type.   They use a Selsyn system with five connections to the gauge.

All I can come up with is a NATO Stock No. 6MT1/6680-99-881-8694 with the description "Indicator, Liquid, Quantity"

[Simon Mc]

Just to answer 'Matchfuzee', In the first photo you can see two wires not pipes going into the back of the gauge.

These are marked with a red sleeve on the + and black on the - earth.

Hope there is someone on here who has a Austin K3 series 3 can tell me if the suggestion by Johnwardle is correct.

I can't find any pictures of the dash/interior of this vehicle online.

If it is British, would the G be for gasoline?  I thought we always called it petrol.

It has a FV number so you can be pretty sure it is British, but if G stands for gasoline, I too have wondered unless it was for some military vehicle that was being exported to a country that referred to petrol as gasoline.
