petrol guage

[DirtyDave]

my fuel guage on my nova seems to have a problem, since yesterday its been ready full all the time except when i go into a roundabout quite fast then it moves down, but when i'm strate it goes up again?
why is it doing this, how can i fix it?
(it hasn't got a full tank in it)

if you haven't been altering your dash then it could be;

dodgy earth, think that it's near the boot for the fuel sender
knackered fuel sender
guage has given up the ghost

i'd try the earth first, as it appears to be reading at fsd.

the guages are the originals, but its never been rite since i bought the car, always reading high eg: ?5 half tank, ?10 3/4 tank, ?30 well over full tank, but then yesterday morning it was reading half then i went out last nite and it was reading full and i put a tenner in it and it went up a little but hasn't come down any.
I've put some fuel in a jerry can so i'm gonna run it out and see what the guage says then.
i'll try and find the earth and re-do it.

Thanx

Dave
