Hello all, an excited new Case David Brown 1210 4x4 owner here. Have good memories of the old David Browns here in Texas but have never had the opportunity to get one but finally got the chance and picked up on old 72' model for restoration. If anyone can tell me how to install a Simms injector pump I would greatly appreciate it as I got the tractor without one. It seem the PO removed it and I found one to install but have never installed one and really dont know where to start. I have restored a couple of other old tractors but this will be my first DB. Any help is greatly appreciated. WW Texas
