Default ‘68 gas fill issue

Anyone else have this problem?
the gas station I go to has nozzles that pump fast if they are put in modern day fuel fills but no matter how I position the nozzle or hold the collar back the damned thing refuses to fill my ‘68’s tank faster than a trickle. I let the attendant who thought I didn’t know what I was doing try (against my better judgement) but he couldn’t do any better. I’m thinking of welding a modern fuel fill to an old cap to use when I fuel up.

Never really bothered me when I had that big hole. Nevertheless, you don't need to weld anything. Get a metal plate, drill a smaller hole for the nozzle and the ring of holes for the bolts and just bolt it in under the big hole with a couple of gaskets.

Mike,
I wonder if this is by design of that particular station's nozzles? I fill my wide neck '65 tank regularly by just holding the collar back and the nozzle pumps at full speed. Maybe before you modify anything, try fueling up at another station and see if the problem goes away. Then you'll now fer sure.
Cheers, Greg

I have that problem in my '72 at some gas stations, but not all. I find that if I semi-close the lid on top of the nozzle it seems to work most of the time.

I need to ask, have you tried other stations? I have a 68 and have never ever experienced that. I just hold back the rubber thingy and let it rip.

Costco has an added spring loaded rubber thing to prevent spills. I just push the nozzle down and use the gas tank rim to support the rubber part. When it gets near full, I pull back on the spring loaded unit and pull the nozzle back a bit.
ALWAYS have the nozzle tube touching the tank rim. Static electricity can ignite the gas by flowing through the hose. I was a three year Army fuel handler. Lou.

You kinda hit on it, the station I go to is the cheapest price in the area and is also a mile from my house.
If I’m on the road I guess if I find a station that’s not gouging I’ll try them.
I realized one day just how mad I was about current events. The station I went to with my motorcycle had a different price for cash, .10 cents cheaper.
Fine I’ll pay cash . I round it up to .50 cent mark topping off the tank figuring it’s be easier for the guy t make change. Nope, he’s gives me change .50 cents short telling me he has no change. Then he says put another .50 cents in. I tell him I already topped it off, it’s a bike, how much does he think I can put in? He says “oh well”.
. I lost it !
Look my man at these prices you can’t chance ripping anyone for one thin dime so I suggest you find that .50 cents !
Ya, I guess his “oh well” was the straw that broke the camels back but he found that .50 cents and has been super polite to me since.
When and if prices ever drop to pre-Joe levels I won’t worry so much about .10 cents here .50 cents there. Until then I’ll be going to the cheap station slow pumps or not.

I wonder if some nozzles are designed to work with back-pressure inside the tank in order produce full flow.
That would cause the nozzle to trickle into a large opening because it doesn't "know it's in the hole"

Maybe, there’s definitely something going on.

My hole is large too, I'm guessing it spent time in prison

It's the pump, or the user, not the vehicle.

Well I know that. Not the user because I pumped gas at 2 different stations as a second job before my career at the Sheriffs Office started. I also let the guy at this station try and he couldn’t get it to work either.

The same thing happened to me. It turned out that the pump was bad. Jerry

Lt.Mike, do I recall that you are in California?
Their vapor capture fillers are a pain, they don't dispense unless the hose is pushed all the way "in", right? I'm not sure how they'd operate with the large opening the early C-3s have.
A large circular plate, that you place over the gas filler, with a hole for the nozzle may be what's needed. Then you're pressing the hose against the plate.

Do the '68s have the rubber bladder in the tank?

No, just a steel tank.

I live along the New Jersey Shore about 8 miles from the beach. As bad as prices are here I’m glad I’m not paying what California is or dealing with their MV laws. The fuel fill on my tank is really big and is the actual top of the tank, you can look right down into the tank.
positive side is its spotless and was obviously replaced. The down side is having been replaced the build sheet that was on top of it is long gone.

Ah, Joisey! Which exit? 🤣
My cars have the huge fill neck too - makes it easy to see when they're full!

My '72 has the huge neck also, never thought about it before but is that original? or should the opening be an abbreviated one, so that (back then) you didn't accidently put the 'regular' fuel in it?

FYI....if you have a charcoal cannister in the engine bay dont top off the tank...leave an inch or two to keep the cannister from becoming fuel soaked...in case the tank purge valve is going bad (per forum sages)
