The boost solenoid isn't necessary. The only function it serves is to provide an "easy" method to boost yourself, in the very rare times that is required.

Having said that - it's pretty easy to verify and/or replace as needed (it's a very simple device). I replaced mine for under $15 - IMO, that's a lot of insurance for such a low cost.
