#'s on 24 injectors?

I just got some new injectors that are supposed to 24#'s but the top is off white instead of blue.

Here are the part #'s on the injector...

F5TE-C1A
0280150991

Please help!

heres the numbers on my light blue ford 24#
F1TE-D5A
280150947

Try scratching off the white on one of them to see if they are blue underneath , maybe someone painted them ???
