Bad Float?

Hello everyone,

The fuel gauge on my 2000tc is working intermitently. I have had someone testing it and it seems fine. What can be the other causes? A bad float perhaps?

An intermittent fault is more likely to be a bad connection somewhere. The float will either float, or sink, and although it's possible for the float arm to stick intermittantly, I've not come across it on a P6.
 
The gauge has been stuck marking 1/4 , with the tank full of petrol, in the last couple of days. It comes down normally when I switch the ignition off, but does not seem to go any higher than 1/4 when on. Any guesses on where I should look first? Cheers
 
That doesn't sound to be what I would call an intermittant fault, rather that it just reads incorrectly according to how much fuel that you know is in the tank. I'd remove both the wires from the tank unit, and with the ignition on, earth the supply wire from the guage, and see if the guage reads full, and then join that wire to the earth and see if it does the same. If you get a full reading both times then the tank unit is faulty. Only option then is to remove and check it, but only do this in a well ventilated area, with as little fuel in the tank as possible.
 
Thanks Harvey,

One thing I forgot to mention is that the tank breather seems to be clogged, as it is very annoying to fill the tank up - the nozzle keeps stopping during the process - it takes ages to have the tank fully filled. However it isn't always like that - sometimes it seems to be fine. What I've observed is that whenever the the nozzle does not keep locking during the process and the flow is constant, my fuel gauge does not complain and works absotely fine (it shows full tank when I finish). Any ideas on that?
 
I'm pretty sure that is just a coincidence. The P6 is a known bad filler. You have to get the angle of the nozzle just right and even then it is unlikely to be able to cope with full flow from the pump.

Hello,
I've come accross a tank fitted with a working sender for 20 quid. Do you think I would be better off to change the whole tank instead of just changing the sender. It seems to me to be quite tricky to take the sender out with that funny ring, being underneath the vehicle...
 
Agreed, definitely the best policy. But make sure it is the same capacity tank. V8's and 2200's have 15 gall tanks, 2000's 12 gallon. The cardboard divider in the boot is in a different position for the two types.

Thanks Chris,

That's a really good point, I did not know they had different sizes. I'll make sure that it is the right one before carrying on. Also, I have noticed that my fuel lines are quite rusty and I am afraid to split them whilst changing the tank...

By the way, shall I take the opportunity to apply any special treatment to the tank to remove any durty/gunk?

Andre, the fuel lines are mostly made of plastic. It's just the curved pipes coming out of the tank that are steel and they're held on to the bottom of the tank by unions and olives. If you're patient you will be able to separate them and reuse them.
