:confused:How can I tell if my sample tube is matched to my injectors? I bought the car with alot of mods done to it already and I was told to check the sample tube, but i dont know what i am looking for. I found out i have 42# injectors, it is a 73MM MAF. Anyone have any ideas. I have no clue at all. This is the first time i have dealt with aftermarket performance mods on a computerized car. Thanks alot. I am really not dumb, but i have not run across this before
 
You will have to look inside the MAF. Inside the MAF will be a smaller tube that is a bolt in tube. That tube will have a color painted on it. Post up the color. I don't have them memorized. You can search the boards to see which one is right for 42 lbs injectors.

Thanks guys! I will check it out. Only 1 more week and i should be able to start working on it!
 
Are you sure you have 42's?..You said a dark blue ring on your injectors no?

They are the exact same ones posted in the pic on the NY chapter forum. He said they were #42. I guess i will take his word for it unless someone disputes it.

Damon just look at the thread in the NY chapter forum lol, i posted a picture of injectors with the same color ring he has. And they are 42lb injectors.
 
I believe he posted a stock picture and not of whats on there. Earlier he stated it had red rings which are not 42;s/ Thats why I asked.
