Raw fuel or just running rich smell? Raw fuel strat with the basics, check all the lines and hoses. check around the fuel pump, carburetor, charcoal canister and if equipped the rollover valve. also check on top of the fuel tank. If it smells really rich there are a lot of possibilities. I would check float height for the carburetor first. Another good suggestion is to carry a fire extinguisher!

Vapor lines on top of the fuel tank are my first guess. The ones which return to the charcoal canister.

+2 on the vapor lines. Depending on their age they are probably cracked and leaky. I know mine were when I replaced them last year. The soft line at the tank leading to the hard line running up to the pump was bad too. Fuel was literally seeping through it and dripping on the ground.

Your '76 started out from the factory with a fuel return line and a vapor canister system. How much of it is left?

This is a link to the 1976 Jeep Factory Service Manual:

Look up Section 4A, most likely about page 18 in that section.

But that's just a guess; it could be the carburetor too. Not too much info to go with.

Hope the FSM helps.

I'd rather be lost on the trails than found at home!
