Chemical injector hose length?

I just purchased a new 15 gallon container that I only have room for at the rear of my trailer. My question is, what’s the maximum length of hose that will allow for efficient vacuum to the injector? I believe this run of hose will need to be ~5 feet. Thanks. Also I believe it’s 1/4id hose.

That will be fine. I know some guys run almost double that.

Great to hear. Thanks.
