Checking/Fixing a fuel gauge.
I've got a feeling my fuel gauge isn't working, it might be but I don't think it is. It sit's a three quarters full, even when
the car's turned off. I think it was lower than this when I bought it and put £90 in but I can bet sure and I put £10 in last week and it might
have moved but I might have imagined it.
I'll probably just brim the tank next week to see if anything happens but is there an easy way to check if it works without putting fuel in or
taking it out and what should I try to fix it if it is broken? Could I get something thats easy to fit that will tell me when I'm low as I
don't appear to have a warning light for fuel.
It's a '90 eunos roadster is it makes a difference. From a quick image search I'm guessing the fuel needle doesn't drop to
empty when the engines off in a alot of these, is this actually the case?

Mine ('92 Eunos) doesn't drop to zero when the ign is off.
You must have stuffed the tank totally full and beyond as I can't even imagine being able to put £90 of fuel in it (unless it's mega
expensive where you are).
The guage seems to be very slow to respond when fuel's been added - it must be well damped - put fuel in mine today and it took a good ten
minutes for the guage to catch up.
If it isn't working and unless it's a simple connector fault prob the easiest check it to remove the dashboard and see if the printed
circuit on the back is still conducting.
I've just fixed my temp guage (opposite end of the dash to the fuel guage) by repairing the break in the printed circuit by carefully scraping
back the insulation, soldering then coating with Araldite to insulate.
HTH.

Thanks, It might have been less than £90, my memory is a little hazy from breaking down a couple of hours later but I put in a lot of fuel. I'm
sure it didn't reach the top so it might be that the gauge won't go all the way over, I'll find out by brimming it, I thought about
putting a stick in the whole to see if I could work it out that way but then I realised I know there is some fuel in there and with no knowledge of
the tank dimensions or what have you thats the only thing I could prove.
I could do with taking the dash off anyway as the light bulb for the fuel gauge doesn't work either.
I feel a bit better from what you've said as it might not be broken and I've only done 6ish miles since I filled it. The biggest problem I
have is I have to go down the dual carriage way to get anywhere and I'll be in trouble if It breaks down there.

The Eunos has a 45 liter tank, so even if you had literally drained the tank dry, you would have had to pay £2 per liter to brim it for £90. Unleaded
peaked at around £1.42ish this year...
