4BT compressor wont start

I have an old 4BT compressor I bought a couple of months ago. It is all mechanical, and has always started right up. After I changed oil, oil filter and fuel filters, I cant get it to start. How do I prime this? It has fuel in both filters when I unscrew them, so I'm stuck on what to do next.

Thanks!

Should be a lever on the lift pump if it is the rotary IP, prime button if it is the inline.

Push till you hear the IP overflow valve hissing, you might have to crack an injector line or two as well.
