Will 1980 injectors work in 1983 turbo engne

[123mike]

I have a parts 1980 engine. Are those injectors the same as a 1983 turbo?. It’s a 300d. I have an injector leaking and I don’t think it’s the return hoses. Maybe the metal return fitting is leaking or above the return hose.

Side note. I blew into the return hose and it seemed a little restricted but I was able to blow air in. I suppose the return goes back to the tank. All thoughts appreciated.

Will any deep socket 21mm. Work to take injectors out? Mike
