how to identify these injectors?

[derick's gn]

i have goggled,gaggled,giggled i even ran these numbers thru the flux conbobulator with no luck. how do you find out what size injectors are by the numbers on them? the numbers on the ones i have are 3303 01d030b and 3293 010d030b. i know that this topic has been beaten to death but is there any easy way to indentify injectors?

thanks
