Injector pump AT vs MT
 

I am rebuilding a 1983 240D with a manual transmission. I found a freshly rebuilt injector pump on Ebay and purchased it for about $200 plus shipping. When I got it, I noticed it looks slightly different than the old injector pump I have removed. Then I found out it is an injecotr pump for an automatic transmission 240D.

Is there any problem using and AT injector pump on a MT vehicle?
