Just pulled the fuel sender out of my mk2 escort drop tank and it's pretty well toasted.
Anyone know of any replacements that will do the job. Wondered if ford used them in any other models.
I have read the UK version of the sender is hard to come by but wondered if the Aussie drop tank version
Was any different.

Why is the sender "toasted"?
Should all be repairable.
 

Hey Peter,
 
Would be very happy if you are right on this one. Took a couple of photos of the senders current state. 
The next question (if you believe it is repairable) is can you recommend anyone to fix it for me. Knowing
my abilities I am happy to out source the repairs to get it back up and sending again...

Everything is fixable. It is just time and money.
Looks almost brand new to me.
 
Assuming the float still works all you will need is:
- a new seal to the tank. Any good spare parts shop or carburettor reconditioner should be able to help.
- a new fuel filter. Any good spare parts shop or carburettor reconditioner should be able to help.
- a new resistor card. MIA Instruments at Maryong NSW (Blacktown in western Sydney) should be able to help you with that. Or if you know a good electrician he can check the resistance wire specs and rewire using the same card (assuming it is not damaged).
 

Apologies I have given you incorrect info.
 
The company is:
MIS Instrument Service
Ph: 9621-8190.
 

Thanks for that Peter. I really appreciate it. Long list of jobs to do so it is a big help to get pointed in the right direction.

Check the instrument voltage regulator. 
It is a "thermal" type regulator using a bimetallic strip contact to drop the voltage used by the fuel and temperature gauges. The output of this regulator is a pulsed voltage that averages down to around 5.6v rms.
It looks like yours may have failed and placed 12v across the gauge and sender ?
That would have the effect, on the sender, of burning it out.  The gauge may have been damaged as well.
As a test...
If you connect a 22 ohm (1watt) resistor from the fuel sender wire to ground (chassis) your fuel gauge should show about 1/2 full.

Does anyone know the resistance figures for full/ empty on underbelly escort tanks. Got some new gauges and want to know if they are compatible. Thanks,
Len

Has anyone had a fuel sender unit repaired lately. Google says that MIS Instrument Services is permanently closed. Just wondering if there is a good alternative place?

Regarding the fuel sender it’s supposed to be 90 ohms empty and 10 ohms when full according to Ford. In the real world mine reads 75 - 15 respectively. My VDO gauge is matched to the sender and works fine. According to VDO the sender should be 90 - 10 ohms.
