Trying to find a part.

[CaliforniaSuburban]

I have a 1990 R2500. I'm trying to figure out what the part is called that is above the throttle body that the 2 fuel injectors are in. Because one side has a crack in it and is spraying fuel all over the place. Where would I be able to get one?

You have 3 ways to fix:
1. Replace the entire TBI assembly
2. Go to the dealer and see if just the upper TBI assy. is available and also purchase an overhaul kit. I suspect the upper TBI assy. is not available.
3. Check a salvage yard for a serviceable TBI unit

Option 3 is probably most economical. Good Luck!
