Re: Fuel Pump Leak?

Looks like a dual function pump/vac/fuel.
I like to put a fuel pressure and vacuum gauge on my old cars to help diagnose what's going on. Those small 1" round ones.
If the pump was rebuilt and installed correctly, and is putting out the right pressure, then it should not leak for some time. But no way to look at a picture of some stain and diagnose issues over the internet. That's wishful thinking. I'd go around and check the screw tightness just to be sure. Sometimes they get missed uneven torq.
In a dual, if the diaphragm leaks it can go into the vacuum side and not be noticed at first.
I was having a rash of bad new mechanicals and opted to go full electric. It was a manufacturer issue, not a rebuild. Whatever works.
