I have a craftsman lawn tractor with a Briggs and Stratton 19.5hp engine vertical shaft model 31p672 0912. G5. I'm trying to find out what this part is, I'm thinking it's at least part of the fuel pump? If someone can please help I would greatly appreciate it. 20230421_200526.jpg20230421_200815.jpg

thanks VTX1300, Mark
Your carburetor part # 591734, if description does not say B&S OEM Part, it will not work properly.

No problem, I’ve looked at everything I can find and I can’t find a diagram with that part in it, I believe it’s the original fuel pump

That is the EPA vapor line/roll over protection valve that mounts into the top of the fuel tank on riding mowers.

Not the fuel pump.

Where'd that part come off the engine from?
To the left of the starter, it looks like the mounting plate is part of the dipstick tube, as you can see in the picture to the right of the rectangular plastic plate.

Didn’t realize that because the gas tank is missing, could the fuel pump mount to the rectangular plastic plate in the photo or where does it mount because it’s missing as well

The fuel pump normal location is on the blower housing next to the air filter cover on what would the left rear of the cover if you were sitting on the rider seat with a vacuum line connected to the dipstick tube for the pulse line. It is held on with two christmas tree fasteners on the newer models.
