If get home equity loan from rental property in 2018 to pay part of the primary residence mortgage acquired a year ago, is the interests deductible against rental income?

I have a rental property paid off but have a primary residence carrying mortgage, I would like to get a fixed rate mortgage loan (Not Home equity line of credit) from the rental property to pay part of current primary residence mortgage principles, is the home equity loan interest from the rental property tax deductible against the rental income? Thanks,
