What injectors are those
 

Hi,

I got a set of yellow side feed injectors, which I'm not sure of what parameters they have.
On one side I found small UJ logo - which I suppose means Unisia Jecs.
On the other side there is A46-00 symbol - but this one seems to be used on many types of injectors...
On the top side of it I found something like 780 on one side and 0100 (I guess so, a bit difficult to read) on the other side.

Does anyone know what are those?

cheers
