How to stay active in research when my faculty job involves mostly teaching and administrative duties?
Where do you expect the funding to come from? In my experience, in UK and other European countries, the research funding comes from successful proposals to the relevant funding bodies. There are research centres that were established and keep going only because the staff there constantly submits project proposals (somebody told me that the success rate is 1 out of 5 or maybe even lower).

You are on your own, so your best bet is to find out what funding bodies can sponsor research in you location. Then you have to come with an idea about a project but keep in mind that most often than not the funding bodies have priorities, which change on regular basis, e.g. every year, and it is VITAL that your proposal fits their priorities. 

Whether you personally will have time for research is another matter. If your college is not very interested in research, you might have a heavy teaching workload and would be able to spend time on research during the breaks between the academic terms. You might have enough funding for one or more PhD students, who would do the majority of the work while you supervise them.

There is another option, which might be not applicable in your research field as you mentioned you need a lab but maybe part of the research could be done this way – find undergrad students, who are enthusiastic about your research ideas and would be happy to do some work for free (or as a part of their assessment – coursework, final year project, etc.). That is how I started my research career many years ago (as a 2-nd year student) – one of our professors invited several bright students from the courses he was teaching to take part in a very innovative research. We had the first results after a couple of months, which allowed the professor to secure funding for several further projects. Then we could buy more equipment, attend conferences, there were several PhD grants as well.
