Fuel pump recommendations 1971 350
Does anyone have a recommendation for a fuel pump for my 1971 350 C3. The one that’s in there is 10-11 years old and I suspect the check valve is bad, causing the hard starting and long cranking. I did look at RobbMc pumps, but they are pricey. Im just afraid to buy a Chinese POS. Thanks, Steve

I have a 69 and they are different, but I believe basicly only in appearence. I don't think there is a check valve, some of the filters in the inlet of the carb have a piece that acts as a check valve, but I certainly may be wrong. If you do disconect the inlet line to check the filter you may want to crank the motor over to check for the quanity the pump is putting out. As to type, it seems like you take your chances. Good luck

Perhaps fuel pump Carter P/N M6955 will suit ?
OR
Delphi P/N MF0026
can't help w/ CoO; that changes frequently
?*?* have ya sniffed your crankcase oil to see if there's any fuel dilution ?
*** On both '71 C3 Qjet I've had, when I parked em Nose-High for long, they'd tend to drain backward and siphon from carb.

The big problem lately with oem style replacement pumps from Carter and AC Delco is too much pressure. They are often in the 9-10 psi range. Way too high for a QJet. I ended up having to run a fuel pressure regulator for my QJet because of this issue. Good luck. Sometimes you get lucky and the pump is in the 5-6 psi range. I wish I kept my old one. I did an engine bay refresh and replaced mine with a Carter Classic car series pump. 10 psi - not happy.

Does the fuel filter in your carb have a working check valve in it?
Since you asked for recommendations, I'd recommend you investigate in-tank electric pumps, with a separate fuel pressure regulator. It will let you dial-in what your carb wants now, and will make you EFI-ready for the future.

About 8 years ago I replaced the fuel pump on my 1969 350 with a NAPA B-0172-P. It was made in South Korea and said withCarter technology. It has been perfect.
Also, when Lars rebuilt my carb he said to not install the in carb fuel filter.
