Hey,
Funny or not so funny thing happened at my local gas pump(depending on your pov). I used a small funnel in my gas filler tube so I could gas up my car today. Previously, I could not get the nozzle into the tube as they have all these humongous rubber bladders attached to the nozzle. If you don't get it seated against the tube the pump won't operate thanks to a safety switch in the bladder.

So.... I used a small funnel today and voila!! The nozzle fit, so I put the trigger lock on and was enjoying the view when I saw gas pouring out of the nozzle and all over the ground!! Ooops. So in the "lessons learned" book, I have learned to pump it slowly and by hand. The attendant came right out and mopped it up as I apologized.

So to all you 49-54ers out there, be careful gassing up. I haven't seen any old style nozzles out here in Lotus Land so far.

The 1049- 1952 cars have a well vented gas filling system. If they don;t accept gas at full flow something is wrong.
The 1950-1952 also has a filling whistle that stops whistleing when full. It is activated by the air passing out of the tank as the gas enters.
I would suspect for all of this to function properly the nozzel has to be well into the filler neck.

My vent hose got plugged once from the inside, as the gas had eaten and blistered the rubber into a ball of goo. The vent got plugged, and same thing happened...gas everywhere. It's likely time for you to replace the rubber hoses...

Actually there was no plugged vent or hole and it DID accept gas at full flow.

The problem was the gas nozzle would not clear the door opening to make the fit into the gas filler tube, with the large rubber bladder attached to the nozzle. Gas went in fine once I installed a funnel to accommodate the larger nozzle and handle with all the rubber junk.

If I can find a pump with just the metal nozzle, it fits fine like the old style gas pumps. Today's modern pumps have these rubber bladder seals with interlocks built in so if the nozzle is not firmly seated in the tube it won't pump. I've had to hold the nozzle just in the tube and hook my finger under the seal to activate the safety switch to operate the pump. This was at an Exxon Mobil station in San Diego.

Pumps I used back in VT didn't have all these gizmos.

Welcome to California. Where we live in Oregon we just have plain nozzles with no rubber bladder seals. We also don't have self service either. yay

The do-gooders convinced the authorities that normal everyday citizens in AreWeGone? were not capable of safely filling a gas tank from a pump. An example of once on the books it is difficult to remove a law. Even though there are hundreds of millions of other USA citizens that can accomplish the task apparently there are a few in power that still don't think so.

Heck, I like the law of no self-service. I don't have to get out of the car to put gas in my tank since they do it for me just like the good old days.....and they even wash my windshield too!

It is nice not dealing with some dude in a locked up security building and also paying money in advance before getting gas even though I don't know how much gas I will need. Yep, in Oregon I just drive up to the pump, tell the attendant how much gas I want, he puts gas in the car, I pay him directly and away I go! No muss....no fuss. What a neat concept!

Actually same thing in New Jersey but for a different reason--to provide more jobs.

Actually, I will add this to my list of things-to-do in retirement. I can scout out gas stations and find a nozzle that fits. LOL willy

The pumps I used in California had a vacuum to suck all gas fumes from the tank as you re-filled it. This is a "clean air" device. That is the "rubber hose" that presses against the filler tube and is around the gas nozzle. Our old cars just weren't made for this "modern invention". Or is it that the designers of this contraption engineered it wrong! I would complain to the State Of California for they are the ones making a problem.

Good point, although complaining to CA state officials is an exercise in futility. Anything related to "clean air" is out of bounds and they either ignore you or lecture you. I tried this with my local tree hugger state rep on the "Crapanol" corn squeezins gas issue and all I got was an uninformed lecture on hydrocarbons.

We just have to grin and bear it. It's the price we pay for living in paradise. I do note however that SEMA does list an old car caucus of folks in Sacramento so hope springs eternal for us old car guys and gals.

Shades of the good old days.

Update on the funky CA gas nozzles. I can fill my car by using one hand to depress the shut off switch at the end of the nozzle bladder, while holding the nozzle tip just into the fill tube. Have to pump slowly or blow back down the vent tube happens. Meanwhile others waiting are getting pissed they have to wait a long time while I pump slowly.
I think I'm going to just fill a 5 gal gas can and fill from that. So much for enviro concerns as this new fangled nozzle causes spills. Take that CA ARB!!

Using a funnel causes spills too as I can't get a good seal. Maybe I'll drive 2 hours to AZ!!! hello2

Hum.....didn't you recently move to California from another state? Due to many issues in California a lot of folks seem to be doing it the other way around. Welcome to California!

I did move there from the frozen Tundra.
Small price to pay to live in paradise. I would swap cars before I moved for this. wink

Have contacted the CA Air Resources Board, which was responsible for mandating the nozzle design change. Got a prompt response from an engineer who confessed they did not test open vent systems on older vehicles. I have sent him pictures, so it's gratifying a state agency is so responsive. We shall see. I also contacted Mobil/Exxon Corporate and they did not offer any solutions e.g. adapters, etc. May resort to filling from a gas can.

Fellow region members here are coping ok with the various challenges to owning an old car here. So far, no ethanol issues with my car--knock on wood.

Where I live the gas nozzles on the gas pumps fit all cars....old and new alike...with no problems. The best thing I ever did was to move out of California. yay bana2

Is the filler nozzle covered with a rubber collapsible boot? N.H. used to have them and may still at some stations but now the ones I go to just have a flat disc presumably just to deflect backsplash. The other style I believe was intended to catch any escaping fumes. Maybe you could fit a rubber "doughnut" over the filler nozzle before pumping to push it back.

The problem is the angle of the nozzle. I can't clear the filler door to get the nozzle seated in the filler tube. They made the nozzles shorter and less angled so with the bladder surrounding the nozzle, I can't get it into the tube.

Other alternatives are filling from a can as I don't like spilling gas on the ground and holding the nozzle with two hands.

I did speak to an engineer at the CA Air Resources Board, which mandated the nozzle redesign. It seems their preliminary study did not include older open vented systems.
As it is a numbers game, he explained there weren't enough older cars to justify fixing the nozzles. Too bad they didn't have the foresight to do a wider sample population during their studies as a better design would be a universal fit.

Update on quick fix. Went to Ace Hdwe, bought a plastic funnel with a long tube. Voila. Shoved the tube down the filler neck past the overflow, stuck my shorty CA pump nozzle into funnel and filled her up. Just have to watch for blow back. No need for anymore gas cologne. LOL

New Update!

Eureka!! (not the town. lol)
Shell stations in my area use a different brand nozzle. It fits!! What a difference a 2 inch longer nozzle makes!

Size does matter. wink
Would urge folks in So Cal to give Shell stations the biz.

Bob,
What's your take on the "Upper Tier" gas thing. Myth or fact?
Just a move to get us to buy branded gas over generic??
Consumer Reports published an article recently, but it seems more anecdotal in favor of branded fuel.

Top Tier fuel (brands that contain fuel injector and intake cleaning additives) is recommended by most major car companies.
I always choose one of these brands as, at least in this area, the prices are all the same. In a 1951 Chevrolet it probably dosen't make much difference.

The above should say intake VALVE cleaning. On some engines deposits build up on the back of the intake valve. At idle the "deposit" absorbs the fuel causing a poor idle condition. Other than removing the head and cleaning the valves walnut shells are used for removing the deposit with the engine intack.
Problem #2 is engines with direct injection. The fuel is injected directly into the cylinder so additives are of no great help. Cleaners can be induced directly into the intake manifold on most engines except some Like the Ford Ecoboost.

As a chemist Rick, you understand the value of Tier One fuel, it's not a hoax.
As Gene stated, Tier One won't make your '51 do burnouts, but its not going to hurt the engine either.
Chipper may chime in, as well.
He's a formula guy, as well.

Agree as long as you buy fuel within your vehicle's octane requirement and don't go chasing additives in higher octane fuels. The Fuel Marketers would have you putting the highest octane in your 75 Pinto which is a waste of money and possibly cause poorer performance regardless if it has super duper varnish removers...

In Canada most of the Tier 1 stations near me also state their Ethanol content which is nice. Typically cheapest grade up to 10% Ethanol, mid grad up to 5% and Hi Test No Ethanol.

That is interesting.....what would I do? .....buy the lowest octane which has 10 percent ethanol and is more than enough octane for a pre 1955 car.
Spend 30 cents a gallon more for 5 percent mid octane (which is not required)or spend 65 cents more for a non- ethanol grade with the highest octane that I don't need or want.

In my home area it is all 10% ethanol. I can drive 30 miles to get either non-ethanol regular for about 25 cents a gallon more (I do get this for winter storage, especailly for my small engines) or pay about 75 cents a Gal. for premimum non-ethanol. (Never do this).

I really have never any problems with using ethanol in my cars.

In my area all we have is the 10% Ethanol junk as well. There is one station that has non-ethanol gas but I have to drive 20 miles to get it. My car absolutely hates Ethanol!

I think the thread is getting a little off subject.

The top tier gasoline vs generic gas has to do with levels or ratio of detergent in branded gas vs unbranded.

Chev Nut makes some good points. I just wonder if I would have less buildup on my recently replaced intake valves running the branded stuff.

I'm thinking Shell is a Tier 1 fuel, plus Shells' 2" longer nozzle works for your car. A bonus, compared to the funnel approach.

The additional bonus would be cleaner valves.

A win, win situation. dance

iagree

Also, I would add that after multiple tank fill ups with the E Gas, no problems so far. driving I put a couple ounces of Startron Fuel additive and some Marvel M.O.. and she seems to like it. Keeping the tank full helps too.

Cheers
