I just need to know what is the best fluid to spray the lines to check for vacuum leaks. Brake cleaner? Carburetor cleaner? Wd40? MAF cleaner? Does it matter? Do any of these work?

Here are directions for doing it. In the link, carburetor cleaner is used. Please remember that if a component that is hot enough is sprayed, it can catch fire, so be careful.

Let me know if this helps.

Take care,
