2nd time buying one with the same results, LEAKS LIKE CRAZY!

I purchased the first one for a project about a year ago and had issues with it leaking,speedway sent me replacement with no luck and finally had to modify it to get it to work good enough. Well a year later and i made the mistake and bought another one for the new project thinking they should have fixed the issues with them by now and i was wrong, its the same junky product and leaked just as the others did. They all leak around the top filler plate because its made of soft aluminum and will not seal for anything. Until they start making the top out of more sturdy material i will not buy any more nor recommend it to anyone. speedway has some good products but this is one they need to pull from there store until they can get it corrected.

What Cap dose this take.? I'm planing on replacing the filler neck I now have,I don't know who made the one I have but I'm using one of these,or at lest one that looks excatly like that in photo here, I got from a buddy some years back. When I first put it on my t-bucket,the cap would not seal,there is no bends at all or scraches in the top were cap fits on,so tryed 4 other caps with the same no seal happening. At that point I found out the cap neck is too deep to seal reg caps. What I'm asking is this one made for reg size caps or some oddball like this old one? And have you herd about these old ones before cap size wise? I've always got great stuff from you,but this was not from you,but looks the very same,so before buying one to replace it,I need to know. Thanks
