Mystery Part Found In Oil Pan

I pulled my F head pan to replace the gasket and i found this in the bottom nestled under the drain plug. At first I thought it was a magnet or something as it was stuck in place and covered in sludge. It is not magnetic, but it doesn't look like i am missing anything from above and the engine runs fine. Anyone recognize it?

 

super curious...i would think with that missing the pump arm wouldnt contact the eccentric and there would be no fuel pumped...no running engine...then again my engine is in parts so ive nothing to base that on

 

I found the same piece in my oil pan when I replaced the gasket last fall. But I'm not running the original pump I have a single action glass bowl pump.

are you thinking "sliding pillow block" cause that doesnt look like one...about half way down that page is a pic of a ac 4693

 

i guess if a pump failed in the past because that fell off and was replaced without knowing the the reason...i could see that

 

Thanks for all the info! I'm willing to bet this is correct. The previous owner said he replaced the fuel pump a while ago. I think i have the old one in a box. Ill check it out. Ill probably pull the current pump just to check to make sure everything is working correctly.

 

When you do, don't lose the sliding pillow block!

Some things are better left alone.

 

I think we have the culprit. This is the old pump that came with my jeep when i bought it.

 

wow, i see it now, but really couldnt picture that being it from the first pics...im happy you got it sorted out!!!

 

You guys a good, good to have people like you to ask questions to. Thanks for being here. Rick
