Just wondering if anyone has any experience with Denso fuel pumps in GM applications. In a general sense, are they a better option than OE? I have an issue with the check valve, and will be replacing the pump assembly soon. It appears the OE part (# 19153374) is made in USA, but that could be NOS. With the high failure rate of fuel pumps in this application, I'm looking into Denso (# 9533052) as well.
