TBI injectors (just humor)

[Mathieu Blais]

if I get it right, the only color I see on all of the injectors (both the
4.3L and 5.0L) is orange, it's like some plastic that cover the two
"fingers".  Could they be the same, I did saw on Wrenchead.com that
replacement numbers were the same?  And as far as the color I see, it's the
same.  And just to make sure I really got them from a 4.3L, cause now I'm
not too sure anymore, does the 4.3L have the same throttle body with 2
injectors as the 5.0L?
