? about napa wheel bearing seal and carb?

[richards72chevy]

I bought some wheel bearing seals from napa and it looks more like an oil seal it even says oil seal on the box.I checked the part number online and it said it was the rite part!Any body else have this problem?Is brown wheel bearing grease ok i have always used the red?THere is a pin in the front of my carb that wont go up or down should i try working it with a pair of pliers?Im pointing at it with a screw driver.I would like to go with the origanal fuel line and filter for safety reasons.Who makes the best fuel line?This is a 72 chevy half ton with a 4barrel 350.I got the carb at autozone a few years ago i think it is the stock quadrajet.Thanks guys.
