I just installed a dual action fuel pump on my Chevy 235, so I can use it to run my windshield wiper motor, but it is leaking out of these four holes I circled. This is the first time I have ever used a pump like this, why would it be leaking there? Are there supposed to be plugs in those holes, what are those holes even for? Also, can anyone tell me how to hook the hose for the wiper motor up to this pump, I see there are two threaded holes near the bottom, do I just put a barbed fitting into one of them and plug the other? I should also mention this is an old pump I found, but it seemed like it was in good shape.
