1996 LT4. I was gonna change the oil and filter on my car this morning. But when warming it up, I smelled gas from the under the hood. Based on those pics, does it look like the FPR is leaking? Last pic, you can see the vacuum leak. Do I just get a general hose that fits, or is a special one required?

You should be able to find a vacuum elbow that size at the auto parts store in the help section. As for the FPR? If it’s leaking gas, then it’s time to replace. It could cause fuel to leak into your cylinders when parked and cause it to hydrolock. Happened to me out of the blue!

Your last picture is of the PCV valve elbow. You can find that in the "Help" section of your local auto parts store.

Fix that elbow for sure.
Don't hesitate to start the car up and remove the vacuum hose from the regulator, if any fuel at all comes out then its leaking.
I don't think its leaking though.

I'll do that for sure. And cool, thanks everyone. I'll go and get a hose that fits to fix the leak.

Put a gauge on it. Key on, engine off and see if the pressure instantly spikes up. See if it bleeds off quickly when the key is removed.

It's not an internal leak on the FPR. It's an external leak. Started the car up just now to see where gas smell was coming from. Sure enough, saw the regulator leaking. Hopefully it shows up in the pic.

Gonna go buy a new one tomorrow. How many o rings do they use?
