Where do primer pumps usually leak from?

[78240D]

Hey everyone!

Here's the situation. My car starting sputtering really bad yesterday and sure enough my prefilter was clogged. So, filter replaced all is good. Now I am noticing fuel seepage where the primer pump (old style) screws into the lift pump, but the 'shaft' of the primer pump is dry. It seems to be seeping with engine static as well. I put a wrench on it and gave it maybe another 1/8 of a turn but still seeps? Any ideas or is replacing the only solution? I didn't noticed a leak before replacment nor did I use the pump at all after replacement. Could the way the car was running (really sputtering) have caused this?

I'm not clear on what you mean by: "It seems to be seeping with engine static as well:
But its probably just a coincidence that it started leaking.
I suggest you replace it, the old style primer pumps were improved to the new style, they are not expensive and you never know when you may need to prime the engine (like when you run low on fuel on the side of the road?)

Where it's leaking from is not the issue...It leaks ,it's Bad/Junk.
Replace it.

Agreed. What does it matter where it leaks from?
Leaks = Bad
Plus, they don't cost much at all......

It costs $15-20 and takes 5 minutes to change, replace it.

I'll agree with most, it's usually an internal leak, replace it.
