An oil leak as a result of a bad fuel pump is not the problem. Totally separate issues. Where is the leak coming from. The 4.2 is prone to leak from the valve cover, rear seal, PCV, dip stick, oil filler cap, etc. Each problem has to be addressed individually but it's not because of the fuel pump. It sounds like you have a problem with the carb. Try to first bring the idle up to at least 800 rpm in neutral with a hot engine. That might solve your problem. If the fuel pump was bad it wouldn't run properly while you're giving it gas that's why I say try the carb first. With a 4.2 carb try the simple fixes first. If you need a fuel pump by some off chance there are two types for this engine; the first has the outlet facing forward, to the front of the vehicle and the other faces to the rear. See which direction you have it will save alot of aggravation if you need to replace which I don't think you have to at this point.
