Leak on top of fuel tank.

[Ron Olczyk]

Anyone might know what might be leaking from top of my fuel tank on 1970 Roadrunner? Leak coming down from side or top of tank on passenger side. Is there a vent or fitting on top that could leak? Thanks. Rons442@gmail.com

There is a vent in that area in a 69. Not sure about 70

A vent on top of tank? What is it for? So gas can leak out of it? How do I fix leak?
Thanks

Should be one that goes up to the shock tower. Then one that goes to a line up through the back seat pan in the trunk and down to the frame rail over the passenger side. You might have to pull the tank. They can rust out up there. Just like the trunk floor pan. A lot of trash can get up in there.

So its a hose leaking? Do I get to it from trunk, behind seat, under car or what?

Thanks

Under the car you will see those vent lines that are by the feed line for fuel.

Are they rubber hoses? So u think it’s leaking from one of those? All feed and return lines fine. Tank sending unit gasket new. Does tank have to be lowered to replace? Looks like leak from top of tank.
Thanks

Nothing on top of tank, if it’s leaking on top you have a hole in top of your tank probably.

1970 will be vented near the rear axle possibly to a canister or junction of vacuum lines I'm not sure but the rubber lines are probably the leak. You can crawl under with a flashlight and see them.

Thanks. I’ll check, but didn’t see leaking hoses. I’ll look again…

It’s a roadrunner, nothing is ever easy to see, find, or reach
