gas filling solution?
 

Those of us that have issues refilling in CA, has anyone swapped out the filler neck for one that has the hole just big enough for the nozzle to fit in? Wouldnt that help with the splash back? I was thinking of taking my necks off (dual tanks) and seeing if someone could weld those in there. Think it would work?

May or may not help but I have a full open hole filler neck on my 79. What I have to do is barely put the pump in there and let it hang down. Like on the last notch seeming as if its going to fall out. Works perfect for me. Hits the angle just right for the flow.

I need a solution to this problem as well. Sub'd for a good answer (hopefully)

I had the smaller hose in my 77. Pain to fill. Swapped in an 84 bedside and 84 tank/hoses that are larger. Still a pain to fill. I don't think there is a "one size fits all" solution for this problem.

Is the issue that the fuel filler location is so low on the side of the truck?

I (sometimes) have the same problem here in Michigan even though we don't have those fancy nozzles.

The only solution may be to tip the truck up on it's side....

Still having issues Gramps?

I know those California pumps are a pain in the butt. I hate it everytime I drive over there. Doesn't matter what vehicle I'm in, it's always a 30 minute session to fill the car.

I turn the nozzel 90 degrees and fill at the slowest pace. Sucks but it works.

Re: gas filling solution?
 

I fill all my cars at the slowest pace, and actually hold the trigger myself, so in reality it's slower than the first click ;)

I do this because I don't trust the clickers, I've had some that don't shut off and poor gas all over the paint. Takes a little more time but it's worth the hassle to have a stain free paint job (or avoid paint peeling, and yes todays gas has peeled the paint on one of my cars.)

My 79 pickup is actually the easiest to fill, being a BBC 1 ton it never had cats from the factory, so it was lead fuel capable. With that said it has the very large lead filler necks. I can lay the nozzles straight down and fill without issues because the filler hole is 3 times the size of the tiny unleaded filler nozzles, no need for the 90 degree trick.

On my classic cars however, with the filler behind the license plates and practically level with the tank, backwash is a real problem so I really have to take my time.

I have the same issue, and when I do the blazer tank swap. I am going to make the fuel neck drop straight down into the tank. Then I will run the fuel fill up the inside of the bed jut to the bottom of the bed rail, and make a sheet metal cover for it.

Beyond that I don't believe there is much that can be done. Because of the 2 bends in the fill line. Most new cars have effectively no or less the 45* of bend as far as the fuel coming in sees.

I have checked my vent line, and it is fine. Plus the fill line is bigger towards the bottom.

What's makes this a California problem? Are the gas pumps different than the rest of the world?

Bunch of BS air quality baffles and seals you have to contend with on the CA gasoline nozzles.

I don't miss those days. I used to flip the nozzle upside down and it would work about 90% of the time. On the other 10%, the local police dispatch was flooded with calls about a 5150 losing his s__t at the gas station.

I ended up swapping over to a later model bed w/ the fuel doors and larger diameter fill hoses. Seemed to fix it.

I have this problem more often with my 2002 Olds Bravada. Believe it or not, my 89 R3500 is easier to fill without a problem. I just don't put the nozzle in to the neck more than halfway. If I hadn't bought the truck first, I would probably be wondering what was going on with the Olds.

Re: gas filling solution?
 

Getting the filler necks with or welding in the small hole items into the necks will not stop the splash back. My truck had them in it, but I did not want to use the unleaded fuels in th edays when I first bought the truck and I punched out the pieces, so I could put in the larger fill nozzles. For the most part, I don't have to much issue with filling and splash back, unless the station has some really good pumps on their islands. I also tend to force feed my tanks, if I have a station with a low priced fuel, so I fill till I see it and it is full.

yes still having the problems and now is the time to find a final solution. Trucks about to get painted. :uhmk:

When I bought my square new in 1978, there was no mandatory smog testing in Kommiefornia. I dumped the cat and went with straight dual exhaust and swapped out the filler neck with a model from a leaded fuel truck. That did the trick in preventing back wash every time I filled up with gas. I swap in the original non-leaded filler once every two years when I get it smogged.

Re: gas filling solution?
 

Does it swap right in without issue? I was thinking of doing that, but could of sworn someone had said it wouldnt work.
I had thought of pulling mine off and having someone weld in that restrictor

Which of these would I order?

Re: gas filling solution?
 

Might try one that uses unleaded as they have the small hole, my 83 has saddle tanks and never have a problem filling up, stick the nozzle in flip the little lock down and she pumps away, only time I had splash back was when I would try to top off manually ;)

Re: gas filling solution?
 

Just take an old sharpened wood chisel and a semi decent sized hammer and slowly cut out the block plates and open up the filler. Mine came out smooth and there has been no issues over the years.

Re: gas filling solution?
 

I pulled my filler off a 74 C-10. It was a direct installation.
