I'm soon to get a fuel tank made or make one myself, just wondering what size (gallons/litres) people have.

and if anyone has internal swirl pots ???

Ben, just about to start mine too. I want a touring range of 200 miles, I expect a minimum of 35mpg touring so 6 gallons would be about right. Normal local use I expect about 20 mpg, so filling up should be about 2 hours apart!

I talked to my local tank repairer about protecting the interior of the tank - he said bugger all, a normal mild steel tank will last about 7 years without any internal protection - so I'm making mine out of mild, easier and cheaper, and yes I am going to have an internal swirl tank. a 2" exhaust offcut with a couple of 1/8 holes drilled in it.

Well if you want to make 2 at same time.... i'd happily take the spare off your hands.

Think I'll go for a 6 gallon too

Mine has got to fit between the rollbar rear supports and will only be 24" wide, but will be taller - taking up luggage space. mind you I will probably cary luggage in the passenger footwell as my Mrs will not fit in the 17" wide apperture - Oversize chassis plans are available, but I stuck with the standard plans - oops. he he he he

I've got standard chassis... and the rollbar supports will go into the boot... just like yours

What's all this about Gallon's? Our garage only sells fuel in litres...

We're planning on getting 150 miles per tank minimum so a 20 litre tank is sufficient working on about 30mpg. 1 litre of fuel occupies very nearly 10cm^3 area, so is easier to work out.
