Cheap cortina fuel tank sender need (Scottish scrooge price though)
Mr Whippy - 12/2/09 at 10:37 AM

Anyone know of a supplier

Cheapest I've found is £60! Get me the ventilator

Alternatively, how easy would it be to rewire it? I suppose it’s just a coil of wire but I don't know what the resistance value would be to replace it with

Cheers

Series Land Rover on ebay for around £ 15 in p+p

These are top mounting and usually have the arm in 2 parts with small clips to join (although I soldered mine) hence should be usuable in a vaiety of tanks.

resistance full - 30 ohm, full 330 ohm (figure from memory) there is miliatry verison that works in opposite way!!

To rewire is a delicate operation, not sure how successful you will be. As you correctly assume, this is special high resistance wire - nichrome - if you did the sums correclty, I am sure you could wire one up.

Are you missing one or the one you have fitted failed?

I rejevenated an LR one by taking the cover off, unbend the small tabs, then clean it up. It is usally the arm that fails to make contact due to white deposit from the fuel (unless the wire tracks are worn), then a bit of copper grease and fit the cover back on, job done.

The top plate may not be identical but you could make an adapter from a metal disc.

I’ve got one fitted, all I know is no power goes through it, not sure a landy one is going to fit and unfortunately to take the tank out requires that I dismantle the back of the falcon which I’ve just finished painting… yeah rather a slight design flaw there! Though the side sender is easily accessible normally. I’ll take the thing off and have a look, perhaps you’re right and it could be easily fixed.

cheers

you have 2 senders?

when you say no power through it, you can measure voltage going to it and the sender does have earth to complete circuit?

you also know the gauge is working - usually disconnecting wire from sender and earthing it will show a full tank.

do you know if the float arm is moving? Is there fuel in the tank?

can you measure resistance across the sender, as before should be in the range of 30 - 330 ohm.

No only one, I just mean that to fit a landy one on the top I’d have to take the car apart

I’ve had a meter on the senders terminal as well as connecting 12volts to it, zip going through the sender. Been like this for years and years, run out of fuel at least 10 times…

Gauge works I connected it directly and it moves. Arms moving up and down too, just seems to be an open circuit in the sender, I’m a bit wary of mucking about with it tbh as I can see the thing burning out and the tank exploding, which would be a bit annoying

I doubt LR one can be modded for side fitting.

current from gauge is low so you are unlikley to get any sparks. also the air space in tank will be replace by fuel and you know about having the correct air/fuel mixture otherwise there would be no need for AA nor RAC nor Eeezestart.

hmmm not sure about tanks not exploding due to shorts -

big tank explosion

The NTSB investigation ended with the adoption of its final report on August 23, 2000. In it they concluded that the probable cause of the accident was an explosion of the center wing fuel tank, most likely as a result of faulty wiring.

yeah, but you are not driving a plane.

^^---- not exactly convincing is it?
