I am subtracting time i.e. 15:03-14:55 and getting :08 as the answer. I
would like to use :08 as a value of just 8 so that I can use it in a
calculation. For example, I have a pump that pumps water 1080 ml/minm, if
it pumps between 14:55 and 15:03 I would like Excel to calculate the number
of minutes, 8, and multiply by 1080 to get the number of mls. However, Excel
calculates, :08 and multiplies by 1080 gets 0:00.

Multiply the time value by 1440, the number of minutes in a day.

Multiply the result by 1440. E.g,

=D2*1440

Be sure to format the cell as General, not Time.

You need to convert minutes first:

In A1, put 15:03
In A2, put 14:55
In A3, put =A1-A2 displays :08
In A4, put =A3*24*60 format as general to display 8
In A5, put 1080
In A6, put =A5*A4 displays 8640
