fuel tank can any 1 help?

[damo]

does any1 know how many liters my sj413 should hold as it can be empty and i fill it up but it will only take £20 to fill to brim wich is roughly only 15 liters. and also when its brimmed the fuel gage only says its half full any help would be much appreciated

I think it should hold around 35litres if I remember correctly? Has it been dented as that will reduce the capacity?

[damo]

yes but only slightly i would say it may take 2 or 3 liters less than it should do

Strange

Workshop manual says 40l
Average price today for unleaded £1.343 = £53.72 to fill from totally empty
I fill mine up at reading 1/4 tank and costs about £40.

Basically your fuel gauge or sender or wiring is faulty. When it reads empty you must have half a tank left.
My gauge hardly ever goes over 1/2 tank when it's full but at least seems to read correct when lower!!

I just do about 160 miles then fill it back up, I'm too lazy/cheap to find out what wrong with mine.

[Darrell]

The most likely culprit would be the tank sender but to check this properly you need to remove the tank and then the sender and then check it's resistance values at the appropriate heights/levels.
More work than I could be bothered with as I expected nothing to come undone or snap off.

Is it a standard fuel tank or has a pervious owner put a smaller tank in it's place?

[donkeychomp]

pervious? I blame Jack Daniels...previous.

Sorry about that
Right then, I can only assume half a tank reading is correct. So why can't you get any more fuel than that in it
I can't think of any reason
