You are probably on the right track by rebuilding the fuel transfer pump. The pump has a "weep" or "tattle tale" hole betwwen the two seals inside that is supposed to deal with this issue. However, this drain hole often becomes plugged with dirt when the problem first starts. You will need to unplug this hole during your rebuild.
There are other places for fuel to contaminate engine oil, each pumping element of the fuel injection pump has a metal to metal seat inside the fuel injection pump, but problems with these are rare.
