Pierre, If you can hook the Float arm with a bit of Wire through the filler Cap ? Move the float arm through It's Arc & see if the Gauge needle moves ..!
Otherwise remove the Sender & test It with a Multi-meter set on Ohms..

Re indicator lights, if it is going on historic rego speak to your club registrar. One way of doing it is to have coloured globes (or LED's) inside the front side lights. Rears can be a more modern cluster . I think everyone agrees that these days it is safer to have two rear lights and direction indicators. If you are going on full rego the indicators will have to have a certain amount of lens area and the tiny tiny bike light may not satisfy that requirement.

Thanks hayseed - tried the wire trick but there's a baffle plate between the filler & the gauge with little room to move. Guess I'll have to pull it out as you suggest & check it. Do you think there should be an earth to the unit as it's bolted up with a gasket between it & the tank?

Thanks mammoth - I'll go with the larger indicators to be on the safe side & keep the side lights as original.
cheers

Pierre I don't know for sure - I haven't got anywhere need that stage yet, let alone think about putting the gauges back in! However, logic tells me that it is a simple wire to the tank unit, that passes through the swinging arm contacts (somehow I guess) and then running to earth first through the body of the sender unit, then into the screws to the tank, and finally through the straps to the chassis. I can see no connecting points, other than the connection from the gauge, on any of the three Bedford tanks that I have here.

I would say hayseed's suggestion is the right approach, especially if you can understand how to use a multi-meter? Sounds right to me. Good luck.

PS I was planning to use the side lights as a combination side light/indicator, although I am mildly tempted to move them down onto the the lower front corners of the bumper bar as I think the guards have a cleaner appearance without them. :unsure: Must admit I hadn't even considered the size factor though, :oops: I've never heard of that before, even when putting a modified older car through the Government Garage.

Would It Be possible for You to post a link that Verifies this Assumption..??

According to this..

pcc.gov.au/uniform/Australian%20Light%20...2%20March%202019.pdf


Pages 71-73.. There are requirements relating to the Position & Visibility of Indicator Lights. But None (that I can See) relating to Lens Size..!

The tanks on old trucks were often earthed through the fuel line. Any flexible lines had a tinned wire braid covering, so were conductive. A wire from a lug under one of the sender screws to any good earth will do.
To test the gauge (assuming the wire from the gauge to the sender is in order), run a wire from the sender terminal to a good earth. The gauge should go off the scale when the ignition is turned on. Bearing in mind there are different types of gauge movements, this is the most common result. This will work regardless of earthing the tank, as you are bypassing that.

IO guess each State can hav e different regulations on position and size of indicator and parking lights. Long time back in NSW they said you had to have 2" square of lense and the old style rounnd lights as used on the Land Rovers met this size. Then during a build of a hot rod, not mine, it was stated that motor cycle indicator lights can be used. So check it out with the relevant authourities first.

Thanks for putting that document up Vic, it is a great resource as it puts to bed some of the old inconsistent rules and urban myths. So, in the case of the Bedford model K, it was made prior to 1966 and therefore is not required to have indicators, and if they are fitted they must be visible at 30 metres, and I guess lens area will be a factor of the very subjective "visability".
Stepping outside the thread a little the regs do not address LED lights or cheapo Chinese lights not marked as ADR compliant. For example marker and side lights must not be greater than 7 watts but what is the equivalent led rating?

As Vic Rhodes points out, Australian Design Rules stopped most of that "each state" BS when concerned with the construction of vehicles. All states are now 99% standardised. If this was not so we would still be driving around in old Holdens because we have zero car manufacturing and no International car maker is going to produce vehicles with 6 special models for each state.

The ADR's align very closely with Euro and US DOT regulations and vehicles from each of these markets only have minor differences and these are normally a case of one or the other getting ahead a year or so before the rest catch up.

Differences come from administrative regulations such as registration requirements, annual inspections, drivers licensing, vehicle write off etc.

Thanks asw20.
When I have the ignition on & connect a wire from the sender to a good earth the needle on the gauge moves up a further 1/16" on the gauge?
