 Topic: Fuel Pump 1971 Ford Torino 500 351C 2VPosted: 16-October-2025 at 7:58AM |

I have concerns on Fuel Pump for 251C 2V. I've cross referenced a dozen times. Bought a Carter M6882 from RockAuto as it looked like same dimensions in the picture. Carter customer service and RockAuto both confirmed it is the right one, even after I sent comparison photos.
They are not the same dimensions when comparing side by side. The new Carter looks like junk compared to the old Carter too. Carter verified the new version is theirs, as I thought perhaps it was a knock-off in Carter box. Side by side, there are some major design issues. The actuator/lever is about 5/8-inch lower than the original, and the diaphragm housing is about an inch smaller. Not to mention the lever fulcrum pivot is a pin held in by bent aluminum vs. the original that has a bronze fulcrum. NAPA pulled one of theirs for comparison, and it is identical to the new Carter dimensions. The point: Has anyone else used the Carter M6882 on the 351C (not the 351W..different pump) with success even though the lever is lower? I have pictures, but it doesn't look like I can add them in this post. |

Unfortunately the fuel pumps have been cheapened significantly in recent times. I ordered a new Carter pump like yours a few years ago and had issues. I went through a few pumps and ended up with a Spectra that works ok. This is probably the best 351c pump on the market, but it's not cheap:

If the lever is lower on the carter pump, it would lead to a decrease in stroke length and pumping volume. I wouldn't run it if that's the case. I've got a stock pump with a doae-e tag on it in a box, and the arm looks designed differently, with the stock arm having more bend to it then the reman unit. However if you compare the pumps by the spot where the lobe hits on the arm they look to be the same height on the OE and reman pump, in that it's nearly even to the top bolt hole of the pump. Unless the pump in your hand is vastly different from the ones in carter's pictures, I'd say it would probably work fine.
Carter makes the pump for multiple sellers. It's for sure been cheapened and had it's components consolidated with similar pumps, that's unavoidable with the "lean" manufacturing ideology present in today's world. IMO it's pointless to buy multiple pumps from different stores looking for a different outcome, as there is likely only one manufacturer for all of them. Napa also sells a delphi unit, but I see no difference in the pictures of the delphi vs carter unit. Unfortunately my local napa doesn't have either on the shelf, otherwise I'd order one and compare it to my stock unit. The robmc pump is better, is likely made from better components, and would come with better customer service if needed, but at a much higher price tag and not as easily available. FWIW I went through 12 brake calipers a year ago for a toyota corolla before I found the one with the correct bracket. Nobody in the corporate world was interested in remedying this situation, or finding me the right caliper. The dozen people I talked to all suggested to continue ordering new ones and returning the wrong ones as defects. Now you know the current state of aftermarket parts (re)manufacturers.

There is definitely some difference between the after market pumps. Here is my comparison I did when I had my pump issues:   The Spectra pump is pump in on the left and it work fine. The Carter pump is next to it and it was junk. The third pump an original Ford pump and that last is an off shore hi-po pump. You can read more about the pumps in my build thread. Scroll partway down the page and you will see the discussion on fuel pumps.

Airtex 60007 is another that was surely fair quality at one time but now like anything else it's a roll of the dice i'd be surprised if Carter is actually making the pumps, are the Carter & Airtex similar enough that they may be rolling off the same line ... wherever? |

A couple of years ago I replaced my fuel pump as the old one failed on the way home from a car show. I found a Carter replacement and compared it to the old one and they were both identical. The fuel lines to the new replacement would not seal and spewed gas all over the place. I returned it and it too would not seal. Both of those units were Carter pumps but...Made in China. I ended up removing the fuel line and returned to the parts store and tested every pump until we found one that would seal tightly. The pump that DID seal was a Carter pump but made in Mexico. Have not had any issues with that pump.
Hint...look at where the pump was made and stay away from that Chinese crap if at all possible.

Probably too late to matter.... But I'm using the Carter M6882 on my 351C. I've had no issues with the lever change myself, never starved of fuel but I did have to add a regulator because my Holley doesn't want what it's putting out. Your mileage may vary.

I'm running the same Carter. It was easy enough to install, but also, I installed it when I rebuilt the engine, so it was out of the car without the power steering pump in the way. I also put on a regulator as a pre-emptive strike after hearing it puts out higher pressure than most carbs like, so I'm glad to have confirmation that I was correct in doing so.
