Managed to get my WRX on the road, and filled her up.

My question do the marks on the gauge have any relation to litres in the tank??


As the gauge doesn`t look to be 1/4, 1/2, 3/4 etc, or are they exactly that?? lol.



If I`m being an idiot sorry, but just trying to under stand what the guage is trying to tell me.

 

You know what that is a very good question. Bever thought of it like that before. lol

Chances are the shape of the tank makes the drain non- linear. That would be why the marks are not spaced equally. Just my theory.

 

But the shape of the tank isnt exactly a cube, the tank has round corners, i think the marks on the gauge will show how many litres are in the tank thats why there not evenly spaced apart.

 

Are we agreeing?

 

Aye mate, agreed. started writing msge at same time as you but by the time i put it into words you beat me to it..

 

But the top of the tank is wide the bottom is narrow, so there would be some difference in the volume as the level got lower. Most petrol tanks aren`t square, and have bumps and lumps. And even then its still possible to have a proper gauge.

Say 50 litre tank.
50 litres is full.
37.5 is 3/4
25 litres 1/2.
12.5 is 1/4
5 litres red line.

The Gauge doesn`t show that at all.

 

My opinion guys when mine goes near the red all i know is it needs some V POWER if not it just won't go caughs splutters then gives up all hope in life then dies with my luck im having prob at a major set of traffic lights P.M.S.L

 

TIP: Regard the "1/4" mark (even though its not spaced evenly lol) as Empty! The fuelling can run lean when hooning round corners with less than 1/4 tank - and curtains, dead engine....
