fuel gauge accuracy

[Michel1960]

I always been intrigued that my fuel gauge indicated almost empty but I never put in more than 22 l even though Triumph states it is a 26 liter tank.

So I decided to do a little test

1. Fill her right up to the rim

2. Warning light came real soon I find ( plus it was evening , that light is real bright  )

3. About 80 km later both the fuel gauge AND the distance to go were indicating ZERO

4. After zero I continued right on ( having brought a small gas tank with me) and went on for 38 km before fuel starvation !

5. Put in 4 liters than I brought and added 19 .5 more at a gas station ( I was real close ) , that makes a total of 23,5 liters . Btw I did 525 km on that tank ( pretty good I think )

Question is where are the other 2,5 liters ?
Lesson is, dont be so scare when fuel gauge indicates low

I don't think anyone ever confirmed it, but 2 or 3 years back I recall there being a post
where it was suggested that the fuel tank capacity for U.S and Canadian markets
was 6.4 U.S Gallons instead of the usual ( and published ) 6.9 gallons.

That would certainly explain your "missing" 2.5 litres !

Perhaps something to do with emissions control, though I can't imagine what ?

The Tank on U.S models is ( was ? ) certainly different in some way from the UK Spec,
as it was subject to a Recall on early U.S models that was not applied to U.K models 

Maybe an email to Triumph asking this very question might provide the answer -
if it does please share !

In any place other than Canada and the USA. The TTSE fuel tank spec  for Canada and USA is 6.3 gallons instead of 6.9.

6.3 US gallons  is 23.84809 liters.

I am not sure why, but we lose 0.3 gallons in many cycles in the USA. Even with my 2002 Suzuki DR200SE compared to other areas.

Just got an answer from UK aftersales and the say the fuel capacity is 26 liters ( I did mention it was a model sold in Canada)

So my question remains , where did those 2,5 liters go!?

Since it is an in tank pump and the fuel is its coolant there is probably no way to completely scavenge the tank.  Doing so would leave the pump exposed and uncooled and you usually leave some clearance from the pickup to the bottom of the tank to allow for settlement of particulates.  These two thing combined probably give you the difference.

Whoever you talked to was wrong. Page 171 of the USA owner's handbook:"Tank capacity 6.6 US Gallons (25 liters)".  Also, various places on the web say the same for the USA TTSE fuel tank spec:

Dimensions and Capacities:
length2235mm
width handlebars858
height without mirror1435-1555mm
seat height770-790mm
wheelbase1542mm
rake27.0º
trail119mm
tank capacity25l
pannier capacity31l
wet weight315 kg

There, I meant 6.6 USA gallons (25L).
