I am in uncharted waters, but at what speed was the 25 miles driven? and what damage has/could have been incurred with the injection pump. Gasoline provides no lubrication to the pump, What damage could have been done.

Having said this, I do hopefully that this is of no consequence and your engine has many trouble free miles in its future...
