I overfilled. Just making sure what I’m seeing is expected.

[kawahonda]

I was a dumbass. Filled it up for the first time with the new fuel system. The fuel nozzle clicked. I figured I'd keep it going. Another click. OK, one more, another click. OK, one last one. Gas came out around the fuel door.

Drove it home and parked it. Nice little stream of gas dripping from the filler neck tube/seal area. It's slowing down now. Already had about a quart drip out.

I did not replace that seal when I re did the fuel system because it looked good. Nice and plump and no wear. I'm assuming this common behavior for overfilling?

Stop at the first click!

Yes that could happen with an old seal...Ideally you'd want to replace it knowing what you've got there...Overfilling the 70 barracuda will get you a nice stream coming out of the frame that's where the vent/overflow goes with the standard tank...

Yup one click is all you can get by with.

Or...jack up  the rear and then keep filling.

Be glad it did not spill out onto the paint on your tail panel.  I rarely "fill" up my tank because I am afraid of that exact thing.

[kawahonda]

Oh it did.  Wipe it off fast and your OK.

Went to a show last month and topped off in the late afternoon. It was +95 degrees out. I didn't over fill but stopped to get coffee before coming home. Came out to the car with a cup of dark roast to see fuel pouring out the back. I'm guessing the cool fuel expanded in the hot tank. Radiant heat from the parking lot probably contributed too. It was a bit scary. Gas was pushing out the filler neck and past the gas cap like water being poured from a drinking glass.

I get fuel on my Cuda tail panel pretty often. I find if I run the gas pump on "full" and let it click, it does better than trying to sneak up on it.

Oh good.  Also, until you run the fuel level down be careful parking on a hill facing upward as this will cause the fuel to spill out more.  I did this once in the Charger at a show and fuel was leaking out of my car.

Never paint your fuel tank black , a friend did this & had a real problem with boiling fuel , we masked it off without removing it & painted it silver & the problem stopped

You need one of these....

Pumped out a quart of additional fuel. No more leak. Gauge is pinged out!

I really screwed it! That's about 2 quarts overfill.

Now it's all good.  Not certain I should replace fuel tube seal. Next time I should end on one click.

When I overfill, I open up the four barrel on way home. Problem solved.

The tube seal shouldn't leak. I would order one and change it out next time the gas level is low, all the fasteners are free now.

[kawahonda]

I wonder if I put the seal in backwards. At any rate, I'll order a new one.

I wonder if it's easier to replace from above (remove gas cap, fill tube, gasket, vent line) rather than dropping the tank (requires putting jack on stands, removing rear valance, loosening tank straps, disconnecting line, disconnecting ground strap, and then working upside side down to replace gasket).

It seems like these were designed for that seal to be replaced from the top...true?

[RUNCHARGER]

Unfortunately the tank has to be dropped a foot or so to change it. There isn't enough room to wiggle the filler tube out with the tank mounted. If it wasn't for a fire hazard I wouldn't stress but I don't take chances on that stuff.
