so i drive my 70 dart daily. i dread goin to the gas station cuz everytime i fill up, the autoshut off stops an spews gas on the side of the car. annoys me cuz im losin abpout $1 in gas alone that is just wasted and eats whats left of my paint. i understand that the pumps have a diameter that fit newer cars. is there a way that i can change the size of my filler neck? some sort of conversion? does someone near me know how? i have 0 technoical skills and wudnt wanna try cutting up anything on my own.

ive asked before and never got a solid answer so im bringin the question up again. i NEED to fix this
 
I would first find out how big the gas tank is. Then (if the gas gauge is correct and assuming you have a 1/4 tank left) just stop shy and finish pumping slowly.
example (I don't know how big the gas tank is so these are just random numbers I'm using.)
full tank is 16 gallons, you gauge says you have 4 gallons left. I would pump 10 gallons and pump the last two slowly. That way you won't spill any.
 
Mine overflows too but heard it was pretty common. I think there is some type of vent line that helps prevent this but still need to look into it.
 
letme know if you learn anything, i just want it to fill normally. i know it sounds lazy, but i dont wanna have to watch how i fill the car, ya know? just wanna fill it n go no hassle
 
When I bought my 66 Dart,I noticed that the filler tube had a bigger diameter tube welded in.(no spewing at fill up)With not having a welder,maybe you could cut the tube and clamp a bigger diameter hose to the tube?(about 18 inches long)Make sure you get proper hose that can withstand fuel.
 
It happened to me onetime and after that I knew the auto shutoff was going to be a problem. What I do is activate the nozzle holder and wait until I hear gas start sloshing around in there. After that I manually fill it up from there.
 
Laysons makes a conversion vent kit to help prevent the overflow. It is pricey though. My '76 Swinger isn't really a problem, but I too listen for the gurgling in the tank and shut it off. My '65 Valiant is a different story. Filler is much lower on the bod. I never fill this baby full anymore. Full tank and a right hand turn equates to gas running down the fender. I just live with more frequent "rest stops". Not a bad thing. The cars always draw attention on the fuel stops.
 
I saw a pic of the conversion for the early A. Don't know if Layson's does something similar for the later cars or not. Best I can recall, the conversion was basically some sort of washer with a smaller diameter hole welded into the fuel filler neck a little ways down from the opening. There was also some sort of removeable plug that you put in there after you filled your tank. The point of the conversion was to keep gas from sloshing down the sides of the car when cornering. Don't know if it helped or not as far as the auto stop feature of gas pumps.

You might be able to take a washer with the correct size hole to fit the nozzle & reduce the outer diameter to fit in the filler neck. Then have somebody weld it into the neck. Of course you'd have to remove the filler neck from the car first. Probably would need to drill a smaller hole in the washer to help air escape as the tank is filled. I think it might be worth a try if the problem is as bad as I remember it being on my car back in the day.
 
they used to sell (back in the late 90's) at pep boys, a kit that they blled as an anti-siphoning kit. it was a large plate (the size of our tanks fill tube) with the smaller fill nozzle hole in it. also had a spring loadd trap door installed, just like a new tank.

now that this thread jogged my memory, im going to starl looking for one to see if it cures the problem, as i am also lazy at the pump.

the reason why the filler tube is bigger in diametre ?

drum roll ...


... because nozzles for leaded gas were larger in diametre . Slightly-smaller than Diesel fuel nozzles , and noticeably-larger than the now-common unleaded gas nozzles .

One way to avert this problem ( I notice you live in Ca . We're stuck with the shittiest "clean air" pumps ; 49 state don't have those irritating an completely ineffectual "boots" on the nozzles !!!! ) is to hold the nozzle upside-down , which keeps the pump from kicking-off and spraying gas everywhere ; and listen for gurgling ; stop pumping when the gurgling starts .

1970 & later "A" bodies have 16 gallon tanks ; '69 & earlier have 18 gallon . I think this was an emissions' concession , as EEC ( et al. ) was introduced for the 1970 model year . I believe that the EEC lines ( Charcoal Canister hard lines ) necessitated the smaller tanks .

My 66 spills all over. I wish the gas fill was higher on the body. I'm sure 69 Chargers don't have that problem. I would like to re-design the fill tube . May-be more of an S shape.
 
my 69 barracuda has the same problem with the flip top style cap , I grab a couple of paper towels from the squeegee rack then twist them up and wrap them around the nozzle seems to work as long as I fill the space between the rubber shield thing and the outer rim of the flip top base , waste full yes but if they would calibrate the pressure correctly it wouldn't be needed

I've come across those PITA boots in states besides California. Never been to California at all. I know when I lived in Maryland over 15 years ago they had them. Seems like some of the other east cost states might have had them too.
 
Here's some info on the overfill limiting valve from the '72 shop manual.

i never use auto shut off when filling my dart. hell its shot the nozzel right out of the car..lol. i always hod the nozzel upside down to fill th ecar and i fill it slowly. the new pumps don't seem to like the older cars.

Do they let you pump your own gas in New Jersey? IIRC, when I drove from Maryland to NYC, it was in New Jersey where they didn't have self-serve gas. That was back in 1994.

Nope. No self serve in jersey. But I always pump into my dart. Screw them. :)
 
New Jersey and Oregon both have "Mini-Serve" and "Full-Serve" fuel stations . You're not allowed to pump your own fuel(s) ; I believe it's a state(s) fire law , iirc .

There was a wonderous grace period here in AQMD-EPA Cali , wherein the gas nozzles ( diesel nozzles haven't been plagued with "clean air nozzles" ) were devoid of those stupid , completely ineffectual vapour recovery nozzles and their thick *** ,heavy *** boots .
From 1994 - c.2004 , we were blessed with straight nozzles ! Just a simple anti-splash shield , and nothing else . ZERO problems filling ANY tank , any vehicle , of any year .
