What size injector do I have? The color is pink. I have a 03 f-150 4.6l extcab short bed 2wd with an auto trans.

 

You are running 19lb. stock and I would guess they originally were orange and now are faded because of a harsh engine cleaner

 

Not faded, the color is not a faded orange, I have two other 03 justlike this one the three of them were bought at the same time. Two have the orange and one has pink!

 

Can you post a pic? This could be interesting

 

I will try to get it and post tomarrow.

 

the 02-03 mustang gt's had pink injectors. 21lbers

 

Now thats funny JDM asked me when they tuned this truck if it was a mustang with a 3.08 rear end.

 

I can not get the pic to post, help any one!!

 

I don't know how this works!!:o

 

It worked. That is the pink injector in my F-150 4.6l 2003 STOCK!!!! Never changed injectors!!

 

Looks like you got the 21s that built was talking about, learn something new all the time around here. Wonder if your factory tune is a little different or did Ford just throw them on?

 

are all 8 pink? if so you might have a pony engine

 

tune would have to be diff wouldnt it?

 

It's only a rule of thumb way of indicating what you have. I have seen red which are a common 30lb, turn out to be 18's. I have seen Lt. Blue common 24's turn out to 19's.
There is a good site, do a google search and type in Stan Weiss injector flow chart. It covers just about every injector on the planet. I have only come across two that were not on that chart myself.
