I have a g35 coupe 2003 the book says i have i think it was 75 litres and i can only fill up to 45 is that correct is the book wrong or do i have somthing wrong with my car?

 

not sure what the exact conversion is, but 75L is roughly 20 Gallons,

When you do 45L, does that bring your gas gauge to full?

 

no it doesn't bring me up to full.

i get 3/4 that is what the needle says i just thought it was my guage broken but i don't know.

 

i have the same problem, its the sending unit

 

One of your sending units is out.

 

There is a TSB on the Fuel Tank where your needle indicator only gets to 3/4.

 

Any links to that TSB... i have same problem... i'm only ever filling up bout 3/4 ways... about 13-14 gallons...

 

ya same with mine this car is a piece of crap compared to my honda

 

Any???? Is this covered by the dealer even if the car is out of warrenty????

 

i had the same problem when a full tank will only indicate 3/4 and sometimes gives false readings... i did the repair myself.. all you need is a q-tip and 30 mins of your time... there is an access to your gas tank on your rear seat.. remove the bottom seat...remove both access covers... remove screws and pull out your gas guage... clean the both floaters with a q-tip and your'e done... very easy repair... dealer said "schrader valve needs replacement"... yeah right... everything is working fine now... gas guage reads full and all readings are correct...

 

Does any one have pictues of the floaters?

 

I think you would have to change the main fule level sensor (P/N 25060-CD00Reference number is ITB05-043)
if that didn't work then you need to change the Shutter valve then i think it would be all fixed ( reference number is ITB05-031)

 

you don't need to replace the fuel level sensor... i just cleaned mine with a q-tip...

here's a link on your fuel system schematics...
