Fuel gauge

I was low on fuel the other day and had to stop at supermarket so just put 20quid in , now I have had it before on a previous car where the gauge doesn't move so that's ok . Any way put 40 quid of shell in the same day and the gauge slowly went upto half. Ive used it a few days fine and the gauge is now showing quarter but the engine cut out just before I got home. So I'm wondering if it's low on fuel and the needle isn't acting correctly going the other way. Is this a fault any one else has seen.
 
How many miles have you done on a half tank of fuel ?

If the best part of 200 and its reading a quarter full and wont start then i would assume the gauge has stuck .. many pipes in the tank it can catch on.

I'm assuming about 400 miles per tank full for this .


Also yes to your question ... i have seen it before .

C4 or any saddle tank and if you don't put enough fuel in when empty then it will stay at empty as its a calculated value below about 1 third of a tank ...

In short it needs to have the fuel lvl above 1/3 for it to be able to see and register a value .

Put what car you have in a signature please :)
 
DeMort I have a 997 C4S and I've just run low on fuel while searching for a shell station (I only put £15 in as I won't be driving the car for a while). However when I got in the car the fuel gauge stayed where it was (low). So I put another £15 in and still the gauge didn't budge.

From reading your post above do I take it that I need to fill it up further to dislodge the sender?

Thanks

Many thanks for that, that explains it :thumb:

I did search but obviously didn't go far enough back.

Thanks again

How do I get 400 miles to a tank? 250 is about max for me.

snap


something to do with a lead right foot I believe :floor:
 
A typo from me i expect , its an old post and i was younger and more impatient then :floor: ..

I never said i was perfect you know .. 300 miles depending on how you drive the car .
 
I've just got 365 out of my last tank (997 C4S) but that was all conservative motorway driving.

Usually I get about 250 max to a tank with more local driving..
