fuel filler problems

-
@wheelsport I'm not sure we have all the info about your issue,

Does fuel come out while you are filling of only at the end just as the nozzle trips off?
how about some photos of the filler area with the gas cap off?

if you force air (low pressure, 5 psi?) into your tank through the fuel filler inlet (wrap tape around an air nozzel enough to seal against the filler tube) does it pressurize the tank (clogged vent line)
 
"Do y’all sell the converted filler tubes or do we have to send in our own to be converted?"

There is a core charge involved. We do have the converted units in stock and ready to ship, but we do want your old one(as long as it's in decent shape...) to convert so there will be more available in the future.

We do not do any sort of conversion for the 67-76 A-body as we have not had any customer feedback saying there would be a need for them.

The conversion kit contains one modified filler tube, a new foam flange gasket, a rubber expansion plug, and a specially modified tool to install and remove the expansion plug. The stock fuel cap fits as it normally would. This positively eliminates any fuel spillage from coming out the end of the filler tube.

So you all do two things...
  1. You install a reducer into the fuel inlet to make it sized for modern pumps
  2. Then you supply an expanding plug that after filling the tank the user inserts into the reducer and expands positively sealing the fuel tank.
Am I correct?

I can't imagine how this would work or what it would look like. The fill pipe restrictor/flap door does the whole job.

I was asking Rick at Laysons about their process, not referring to the spiked insert "tank sentry"
 
Could someone please explain how the tank in a '65 Barracuda vents to the atmosphere? The original tank was missing when I bought my car, but I do have a new replacement. There is only one vent line, and it comes out of the fill tube near the tank, comes up and vents into the fill tube near the top about 1.5" below the fuel cap. the fuel cap is not vented, and I don't see how/where air would enter the tank as the fuel is used up. The service manual mentions to be sure the vent line on the tank does not get clogged with undercoating or the tank will collapse. I could be missing some parts, but have looked at the parts book and I seem to have everything except the rubber seal between the fill tube and tank. The "vent line" can't vent to the atmosphere because the cap seals off the whole tube assembly including the vent line. What am I missing here?

Yes, that is correct.

See post 4 first photo. The small tube from the fuel filler goes down and exits into the frame rail, not the tank
 
Slantsixdan and rick@laysons take it down a notch.

Slantsix obviously has had problems. Rick not representing Laysons well.

Both of you can do better.
 
Thanks, I see it now. It was apart when I bought the car, so I was afraid I was missing something. It doesn't stick out very far from the rubber seal, but evidently it doesn't need to.

I was thinking about all you guys having trouble w/ this yesterday when filling up my 68 fastback , which I have no trouble with at all when filling up.
Much unlike a new 68 fastback I had when I was young , it puked fuel every time , from the factory .
As I posted earlier , its a vent problem , always has been , unless ur filler tube is way low to start with , which magnifies the problem.

I have had problems with refilling my car forever. Gas will burp out all over while refueling. I know I'm not the only one with this problem. I've tried going very slow which isn't really working like it should. While refilling slowly, fuel comes out of the vent tube. I was just told not come back to the gas station until I fixed the problem. Some of you guys have modified the filler neck. I have an idea that might work to stop the fuel from coming out of the vent tube. The fuel gauge sender on my car has a vent line that I have plugged. Will connecting the vent tube to the vent on the sender solve the problem?

my dumb dirtyword 66 Valiant was doing the same.... so.... i bought a 3 ft section of 1/4 gas hose which i insert into the filler tube and then fill up. no burping, etc.

^^^^^^^^^^^^^^^^^^^^^^^^^^^vent problem------------
 
Thanks for the tip on what to try and for the hints on the install. Im uploading what I found at one of the links just incase it doesnt work for somebody else in the future.

Thanks again everyone

I know thais is an old thread but I was thinking...

The newer style filler nozels have a return air built in, to reduce vapors from getting into the atmosphere.

That should eliminate the issue being the air vent in the thank.

I guess there are places that don't use that type of filler nozels?
 
I previously posted a fix, with pictures, that works great, which is very similar to the Tank Sentry. I used a valve cover oil filler grommet that I ground to fit inside the filler tube. I stuffed it about an inch inside the tube. The cost was zero because I already had the grommet from another project.
