Does the color of the injector denote the size in 4.6 engines? For instance, I am shopping intake manifolds and have seen yellow, orange, black and purple injectors on factory Ford intakes. What sized do the colors denote?
Any help would be greatly appreciated.

 

My guess would be flow per hour.

 

yup the color of the injector = the size. I think the stockers are yellow? or maybe and orangeish. They are 19 lb/hr.

I recently bought 19 lb injectors from a '01 4.6 mustang and they are pink.

 

Were they Motorcraft injectors? Maybe they are a different color per car application?

 

Anyone know for sure what flow the orange injectors are?

 

ANYONE???

 

i'm pretty sure the color has nothin to do with the flow rate the yellow ones are self cleaning and the black ones are non-self cleaning,that's all i know about the color

 

Here is the codes I found, Didn't find pink

So they're color coated according to flow rate. makes sense.

 

Found some old posts from Neal and they gave me the answer I need. The flow rate for the yellow/orange is 19Lbs/hr.
