1979 C20 Fuel pump

[mrgm]

1979 chevy c20
454, th400, 14 bolt rear with 3.73
dual tank.

might have an issue with fuel pump. The old fuel pump on it looked new when I replaced it.

I drove this truck 5 hours back home at 75mph when I first bought it. Then just around town with about 10 miles of highway for about 2 weeks. The truck started bogging down at times on the highway. Then left me stranded. Fuel pump went out. When I pulled the old one out, looks like the rod where the pump arm pivots broke. I replaced the fuel pump with what Autozone had. Its been about 7 weeks and about 300 miles later, I felt that bog again on the highway, I have not driven it since. About to give it another go. Video shows filter at the carb. Not sure what it could be and if that is normal. when I first replaced pump, that thing looked to always be full.

Should I use a "heavy duty" pump sourced elsewhere.
