The fuel pump was mounted centrally atop the rear of the engine, driven by a reciprocating pushrod from a lobe on the camshaft. High milage engines were subject to pushrod wear that affected fuel delivery, corrected by the addtion of a simple aftermarket cap to the pushrod.Mike

This was a common problem with the old flat heads..I used to braze a layer of brass on top of the push rod..it dosen't take much..an extra 35 to 40 thousands of brass on the push rod will make all the difference in the world..a air leak on the suction side of the pump is another possibility..as previously mentioned.
