Fuel filter leak? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Sorry for the ignorance, guys. Is this my fuel filter? It’s leaking like mad. Couldn’t figure out why I was dying from fumes on last night’s cruise and this morning’s puddle clued me in.

That's an aftermarket filter that should be addressed. Never seen one like that though so I can't be of technical help there.

That appears to be a fuel filter (not stock, I think), and it shouldn't be on the suction side of the pump unless it was the factory one, which is pretty big, IIRC. I'd just take it out and replace the flex line while I was in there. There should be a filter in the carburetor, unless you have an Edelbrock (I suspect this because that other item appears to be a pressure regulator).

Thanks! Carb’s a Holley. You think just do away with the filter?

Replace with a one piece filter. Please don't use the 3 piece glass filter from your favorite auto parts store. They are fire starters. Just get a regular one-piece plastic unit and call it a day.

I had one of those glass three-piece jobs that Corts60 mentioned on a car once, and it started leaking. Tossed it and put on a metal can type. This filter should be fine if there is no filter in the carburetor, and even then it should be fine. Put it on the line between the pump and the carb, though, and just lose that whole plumber's nightmare.
