All new pumps available for the Stude V8 are actually pumps designed
for the Chrysler 318 engines.
The arm comes out straight and has one bend near the end.
When you push down on the arm it will move easily for quite a distance
before resistance is noted.
These pumps will work fine for normal driving but when you put the
hammer down it starves the engine.
These pumps are made by Master and have a problem with the pivot pin
comming out and bad oil leaks developng in the area of the pivot pin.
Carter also markets a pump for the Studebaker V8 but it is also a
Master pump repackaged by Carter. The only difference is that it is
 marked "made in canada".  Same 318 pump,same casting mold etc and 
the pin comes out even faster.
