Bill, I can tell you from my research and experience of all the aftermarket parts the most likely one to be junk and fail is a mechanical fuel pump. Regardless of the brand. As everyone has indicated, rebuilding an original is your best option. I am on my 3rd fuel pump with a grand total of less than 10 hours on all 3 of them combined. The last one seems to be doing okay and the only reason I put it on is because the 2nd one that failed was a Carter and had a one year warranty. They gave me a replacement at no cost or I would have gone the Then and Now route. If this one fails, they are my next stop. FYI - Carter use to be a quality name in auto parts. I found out my Carter fuel pump was made in China.
Otto, your pictures show the fuel pump with the glass bowl pointing up. I thought they were supposed to be point down to collect any debris coming through the line? My fuel pump only work with the bowl down.
