Well I am not sure if you have a combo fuel/ vacuum pump but what ever you have should not be leaking oil. I think no matter which pump you have you will want to replace it. just my opinion and it is worth what I charge for it.
Good luck

If someone put a hollow bolt in one of these, something's wrong. If you have the combo pump with fuel pump on top and vacuum pump on the bottom, there will be two vacuum lines on the bottom. But since your truck should have electric wipers (I think) you wouldn't need a vacuum pump.

I have the same thing on my 59 235.
There's a small hose that goes to one of the vacuum fittings on the fuel pump, from the hollow stud. Darned if I know why..... | | |
