Gas spills when refueling

[MidnightBlueSwinger]

Does anyone know a way to upgrade or modify the fuel neck on a 1972 Dodge Dart to prevent fuel spill when fueling? Newer cars have a small diameter that fit the gas station pump nozzles

Check to make sure the tank vent is open and operating.
'66 and earlier with the small diameter filler necks are usually the ones that have issues "burping" fuel out onto the quarter panel- usually you don't see that with '67 and later unless there's issues with the tank vent, which is why I mention that.
Or just fill it a bit slower... nozzle doesn't have to be open 4 clicks, fill it at 3 and it'll only take a minute longer.

These cars have suffered that malady since new. While you can improve upon it, nothing really works 100%. Best bet is to hold the pump nozzle sideways, pump slow and stop pumping on the first automatic cutoff.

I take a couple of napkins from the windshield wash station at the pump and wrap it around the base of the nozzle where it meets the car. That way when the gas nozzle ticks off all the gas is caught in the napkin wrapped around the nozzle.

with CA pumps you can't let them run automatically or hands free. pull the foreskin vapor boot back get the spout in with a little english on it and pump slow.

or be prepared to go full tilt. no half stepping.

In Georgia and Florida the non-ethanol has a blue pump gun that is variable pressure. It's very easy to pump in at a slower speed. I find that helps as @Professor Fate mentioned above.

I have what I believe is a 100% fix for it. I plan on posting how I did it when I get it done to Vixen. Gonna be a little while though.

That's what that bag of hole filled socks is for. Stuff it around the filler neck and it will click off properly, then throw the sock in their garbage can!

Thats a hell of an idea, I usually just use a rag, but those old socks could come in handy

 

[toolmanmike]

Yep, they do.

Restrictor plate in the fill tube?
Been considering that myself.

 

[dadsbee]

Trust me, all you need is a sock... I don't blow gas down the quarter panel of this..

Nope. I've seen those, but I've read that's not a 100% fix.

@slantsixdan to the rescue. Sorry about the backread Dan

I like this idea, especially the spill tray. But I still need the trunk space. Do you think I could stuff a 2 inch coupler pipe into the tank grommet and use fuel resistant hose to adapt a fuel neck from a newer model? This is for a F-350.

IF i was going to do this, i'd leave the stock fill tube in the tank-- the whole gasket/tube thing is a ball ache, so best to avoid disturbing that.

i'd couple into the fill tube.

but here's the deal, modern cars fill smooth because of the interface of the cap lock, nozzle and vapor sleeve as well as the fact that modern tanks are vented much, much better than our old crap cans.

so, figure out how to mount that fill to the 1/4 panel, scab it into the stock fill tube and then vent the crap out of it and the tank and you *might* wind up with something that fills more like a modern car. maybe.

That's the meat and taters right there. That's the whole ball of wax. They simply need to be vented better. That'd solve the whole thAng.

I go low tech.

I insert the fill nozzle, but leave it out an inch. I then take a couple paper towels and turn them into a big long fatty (420 man) then wrap it around the filler nozzle. Then push the nozzle the rest of the way in.

I also glow slower than the max and do not top it off

 

[65 Dartman]

Did a car such as a 68/70 Charger have a spill problem with the filler almost horizontal?

The nozzle operator controls if you will overflow. That can be you (treating it like a metal utility gas can laying on it's side) or the automatic shutoff if you equip the neck with the baffle (like the F350). There is a kit for this (somebody share a link?). The little holes should be at the bottom so any fuel that does get above the insert can still drain but a push in insert doesn't fully seal anyway. The insert depth should be set to allow the nozzle tip side hole to go past the insert. The nozzle diameter must also be a close fit to the insert opening. Here is a video on how the nozzle works: Utube pump nozzle shutoff design

You'll still probably leak a bit since the neck does not expand above the insert to form a cup and the angle of the neck doesn't drop like modern cars. A custom neck could drop a few inches initially and expand a couple inches (leaving the entry and cap stock), then run horizontal over the tank. The hinged flap is not needed. You want the nozzle side hole to stop getting air to shut off the pump.

I can estimate how much fuel I need based on my mileage. Then, I listen as I fill.....The sound changes when it is starting to fill the neck.....That's when I stop.

My 63 Valiant was a ***** to fuel. For me completely flip the nozzle up side down. Worked for me.
Same as CFD244 I would listen for the sound and stop.

That is an awesome picture! I love seeing your cars posted because they are all top notch.

My purple car doesn’t leak gas when the pump clicks off but my gts does. I’ll have to see if mine is venting properly or not.

I bought a new Filler Tube from Classic a few years back and it comes with the modern smaller opening. It was great quality. But I like the old larger opening better because when you fill it with a gas can it's more difficult. I don't have ant problems with the larger opening. Just don't fill it all the way to the top.

 

[matthon]

Couldn't one just get a large grommet and put it into the fill hole?
Kinda like a rubber sock you don't have to carry around and remove and toss.

Still doesn't solve the issue though.

I have a TanksInc tank, it has a separate vent nipple. It's connected to the factory fill tube vent, hard line up and around in the trunk, then soft line down and out into the frame, iirc.

Even if I fill it extremely slow it shoots out in the end, sometimes getting a full tank, sometimes not.

TanksInc tank came with a aluminum breather valve, but it needs to be mounted high, which would be in the trunk, no thank you, and I misplaced it.

My other thought, fill tube in my 62 Valiant is horizontal for a mile before it goes south.

Filling from a gas can one day, I stuck a hose on it to avoid wearing gas.

Maybe carry a hose that just reaches the full tank mark and stick it on the pump nozzle?
