As of recent I've been having extreme gas pressure release when I take off my gas cap to pump gas ,and now there's leaking after a drive right underneath my charcoal canister. And there's liquid everywhere as you can see in the pic. Any thoughts if both issues are related? Any solutions for a fix ?

P. S. 3rd photo is from underneath the charcoal canister. You can see the black fluid droplets on the starter solenoid next to the red transmission bellhousing

Your Gas cap vents vacuum or let's air in. Your rollover valves vent pressure to the canister it sounds like you either severely overfilled your tank or more likely something is plugged your vent system between the engine and canister. A third option and mine did this is my fuel pump was overheating badly creating more pressure than the vents can handle it had all the gas in my tank almost to hot to touch

if that was gas... you would certainly smell it. Does it smell like fuel . . .

Stop whining about the 'ride' - If your YJ ain't wrangling your soul free, then might I suggest you buy a stationwagon... at least you can fit all your bull**** in the back.

I think you have your answer then. Now you need to run the lines to see where the failure is. That can turn into a dangerous situation quickly.

Yikes! I don't even like the smell of oil cause that can catch fire too....... although much harder than fuel....

If you cannot fix it with a hammer then it has to be an electrical problem.

Mine was running like crap after I got it and I ended up dropping the tank cleaning it out and blowing about a 100psi down the line. The crap that came out was awesome. I ended up putting a third filter on right where the fuel line comes off the frame and over to the fuel pump. I used a clear filter so I could monitor the crap. Oh my jeep is a 88 4.2 with a carb.

Sure doesn't look like gas to me. Looks oily. What is it, gas or oil? Kinda makes a difference!

I dont know what I was thinking origionally when I looked at those pics. You should check your oil pressure sender and your dipstick when I got oil there thats where it came from.

You also need to find that fuel smell. My fiancee was was killed when her jeep caught on fire. Dont risk it it isnt worth.

That's why I wanted to confirm with the OP if it was gas... vastly different smell.

The texture and its appearance doesnt look like fuel. Its grimey. Dipstick tube may be blowing out oil or even from the valve cover on that side..if it was the sending unit, it'd be all over the place... hood, fender well, hell even the radiator. And i am fairly certain his engine would be seized by now...a sending unit failure can be catastrophic in no time

Doubtful... but a hairline crack on the dipstick tube somewhere on the pipe should be inspected for

Or if your an idoit like me and screw it in tight but not tight enough the sending unit will leak slowly. Definitly looks like oil. I dont know why I was thinking those pics were in the back. Fuel is still nothing to mess around with. It defdinitly hits a spot. I would be worried about the fuel smell first then the oil

When something isn't right with the fuel this can happen and did. Snuffed a life far to soon and took 2 kids mother away.
