He has apologized and offered to give me a refund, however due the fact that the hose is now in Canberra I declined. I've already sent Alex a metre of SAE30 T10.

In the U.S. the SAE spec is SAE30
R10 not
T10
According to my Capt. Midnight Secret Decoder Ring the spec number printed on the hose decodes as follows:
30 is the specification group for fuel, oil, and emission hose. If the hose you are using for fuel doesn't have a 30 at the start of the identification number you can't use it for fuel, emissions or oil systems
R identifies the section of the specification group. The number after the R is the particular set of specifications. These specifications are for things such as construction, permeability, flexibility(bend radius), temperature range and kink resistance. The R number is what determines where a hose can be used; in the tank, outside the vehicle, or under the hood. If this number isn't 10, you can't use it in the fuel tank.
T identifies the revision level for the section. I understand that to mean that whenever a hose manufacturer makes an approved design improvement it can be documented by a new T number. For example: if a new rubber compound that has a better bend radius is approved, hose made with that compound will get a new T number, but the R number will still be the same. The T number will mean that particular hose will be more flexible than other hoses in the group.
The T number is useful to an engineer because it lets him see the differences in a group of available hose that meets a particular application. To the end user the minor differences that the T number represents are almost meaningless and that is why nearly all the hose being sold does not have the T number printed on it.
Bottom line, SAE30R10 should always be printed on any hose you put in your Brick's fuel tank.
