1986 300sdl WVO Fuel Injector maintenance

I have a Mercedessource inspired 2 tank WVO conversion set up in my 1986 300SDL. I have put on 14,000 miles since the conversion about a year and a few months ago. Everything is running fine.

What is the sign that I will see when my Monarch injectors need to be replaced? They have been on for all 14,000 miles. I don't intend to pull them off for the "fun" of it, because quite frankly it is a pain on the 300sdl's (getting to number 3 and 4 requires removal of the intake manifold.) So I want to only do it if needed.

Thanks for you advice.

Car wont start. New strainer, clean tank, new bosch primer pump and assembly, new plasic lines, new feul filters, new glow plugs and all are working, did diesel purge (2 cans). Car runs on diesel purge setup. I'm lost so I took car to foreign car mech (local benz expert) and he tried an electric pump and....ran for one day then died again. He's saying air is getting in lines...but we both have no idea...please help!!!
