Over the years. I've replaced many components on my Vette, and have to keep reminding myself that the best ones are those made by reputable companies, which 99.9% of the time means American-made. Yes, there are exceptions to that rule, but I have gotten to the point where I refuse to take my chances with components made elsewhere.
Now, to be clear, when I say "American-made" that includes parts manufactured in Canada and Mexico, as well as the USA.

I've found many great deals on eBay and Amazon in the past, but there are a lot of fly-by-night sellers on both platforms with prices all over the map, so search and compare prices before finalizing a purchase.
I found the right fuel pump for my 1976 Corvette on CarID.com (link at the bottom of the page), even though the listing did not include my model year. However, from my research, I knew this was the right pump for my car.
As a matter of fact, it may be the same fuel pump for Corvettes (and maybe other Chevrolets with small-block V8 engines) from the late 1950s all the way to the late 1970s, so always take the time to do your research.
Total cost, including delivery charges, was $36.12. A great price when compared to other part vendors.
