Carrying fuel in your vehicle is covered by The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009, which you can read in more detail here: www.gov.uk/government/publications/carriage-of-dan...d but in brief the total quantity should not exceed 60 litres per receptacle and 240 litres per transport unit. However, we would suggest limiting the amount you carry to the minimum, and some fuel stations may have restrictions on how many fuel containers you can fill in a single visit.

If you are looking for a safe means of transporting fuel we would suggest looking for a mesh-filled container which reduces the chances of explosion, such as those available on jerrycans.co.uk
