Vapor leak detection pump leaking?

Hello good people, was removing my spare tire winch mount this morning and realized that the gas tank was caked in dirt from what seemed to be a leak I cleaned it off and did a test drive now I have little splatters over the back of the fuel tank and some on leak detection pump. Anyone have some insight on this?

 

To be honest it is really hard to see. Do you have any other pics? is there any damage or holes on fuel tank?

 

Not that I can see maybe I will upload a better picture after some driving because I wiped the area clean before taking this picture

 

You could just use UV flash light also, it should show. But yes its hard to see in picture.

I personally haven't checked or seen anything yet, if I saw leak on ground i would check probably but none so far on mine. If its wet again it is probably leaking, maybe a stone chip or something

 

Here’s a few more pics I can’t really see any punctures anywhere

 

I’m actually thinking it’s coming from the pinion seal and is flinging diff fluid to the fuel tank.. but it also might not be.

 

Doesn't look like fuel. Fuel would spread more...

 

Drive more worry less it could have been from the road.

 

Yeah thinking it’s diff fluid from the pinion

 

Had a regear done 10k miles ago so maybe pinion seal didn’t get seated properly..

 

It also looks like it got flung onto the exhaust pipe

 

Yes seems like its coming from somewhere else and just happens to be caught by fuel tank because its boxy size. I would avoid driving it until you find where its coming from, if its differential, you dont want to run low on it. Assuming its been spewing since yesterday or whenever you noticed it, maybe longer who knows

 

I just cleaned the diff breather just incase it was that but doesn’t seem to be actually leaking from the pinion just small bits of it flinging everywhere

 

It has to be coming from somewhere, any smells on it? when you wipe it off, you cant see color of it probably with dirt?

I want to say maybe one of the lines is leaking but I dont see any rust or damage to lines so no idea

 

I’m 80% sure it’s diff fluid coming from the pinion seal

 

Pinion seal leak will leave oil on the botom of the diff it is the lowest point and will show up even if it's parked.

 

Good point will have to check after work today Thanks for the insight

 

Looks like it is also slinging onto the tire...?

 

Not sure I rotated it yesterday so it was up front

 

Yep can definitely see some seepage near the bottom here. thanks for pointing that out. Got in contact with the shop that regeared luckily they have a 2 year warranty gonna take it in this week thank you for y’all’s help
