aftermarket gas tank slow to fill?

I thought I saw this mentioned before, but couldn't find any threads when I searched just now.

I put the Spectra RockAuto Special Premium tank in my '83 Malibu. Turned out the original tank was clean as a whistle inside, a dead sender was the only real issue. That tank was scrapped though, and now I'm stuck with this Spectra that overflows if I try to pump at anything more than about half trigger. Makes me feel like a total chump standing there pumping forever while the dollars ssslllooowwwlllyyy roll on up.

Anyone else have this wonderful experience, or should I look for something stuck in the fill tube?

If this isn't just me and it really is these particular tanks, are there any alternatives that fill at a normal rate?

Oh and by the way, the tank didn't fit the same as the original, either. I had to find 1" M10 spacers for the front strap bolts and re-bend the strap.

Funny thing though, the fill tube on the original was too long so a locking gas cap stood the license plate out too far. This thing does fix that problem, at least, so it's not all bad.

Unfortunately, a common problem. There is a fix, but requires removing the tank. Here's a link to a thread that will give you some ideas.

Well, heh heh, at least it helps to have an idea what the problem is, and know I'm not alone. Psychologically at least.

Thanks for that link. Looks like people have "been there and done that." Offhand though I'd say the fix looks like a bit much for me at this point.

From what I gather, the Spectra tanks were fine in earlier years, then at some point a few years ago this problem appeared. And it seems never to have been properly resolved, as far as I can tell.

Spectra seems to be the only option for this Malibu, unless I want to gamble on the Fineline at RockAuto -- whatever that creation might be.
