Anyone know how to work out the Liquid of a Fuel Tank.

Length x height x width (measured in cm)
Divide by 1000 to get litres.
Try doing that in inches and gallons!
David
P.S. Divide by 4.546 for UK Gallons

It gets complicated if you have less than simple shape. Depends how exact you want to be i suppose.

Couple of measurement conversion sites you might find useful:

fill the tank with expanding foam then cut the tank open to get your foam tank negative out and then fill a bath with water to the brim and then
plunge your foam tank negative into the bath and measure the volume of the water displaced, eureka!
seriously though either fill it with water or fuel if its installed, syphon out the liquid and measure it/weigh it
OR
if its not in the car weigh it, fill it up with fluid and weigh it again. you can work out the volume from the difference in weight

if its not a simple shape, just post dimensions - i love that sort of problem  my favourites at gcse were working out the angles of tent posts from
obscure areas etc

me!

Give me dimensions and I will model it in AutoCAD. Give me our address and I will send you AutoCAD and you can model it yourself. Offer open to
anyone.

100x100x100mm = 1 litre
If its an oblong or square, just multiply all the sides together and divide by a million - then you get litres.

If the tanks already made and you need to know the capacity measure the weight of the tank and then fill with water. Then subtract the original weight
of the empty tank. 1 litre of water equals 1kg of weight so you can work out the capacity.

Or fill it with milkbottles full of water, if you can find a milkbottle!
Divide the numer of milk bottles by 8 and thgen you've got gallons

yep, you did, as lxhxw.
I just made it easier to visualise what volume a single cubic litre actually occupied
so there

Ps - Also David, you are being anti american - you didnt give the US gallon fomula - there are certain people that pull you up on these things
so, its
3.7854118 litres per US gallon

That doesn't sound right!
Take an example tank - 10cm x 10cm x 100cm
This is 10000cc, or 10 litres, roughly 2.2 galls.(UK!)
Convert this to imperial - roughly 4" x 4" x 39"
Which is 624 cu in. Multiply this by 6.25 gives 3900 gallons!
The correct mutliplier is 0.0036047, which gives 2.25 UK gallons for the example tank (spot on, allowing for conversion errors)
I'll stick to metric, thank you...
