I have something on the passenger front of my engine, down low that looks like it has a fuel line running into it and then out to a Holley double pumper. Both input and output is at the bottom on the item. Is this a fuel pump of some sort? It looks like it might have oil running to it through the engine and is just a bit smaller than the oil filter in size. I changed the oil today and was checking to leaks afterwards and saw this moving like crazy then realized that this piece was missing 1 of the 2 bolts that held it on and the other was about 1/2 way out! Yikes!
