1967 GT500 Fuel Pump (after market)

My car would not start this past weekend and turns out, the fuel pump is shot. I'm looking for a fuel pump I can pick up quickly at the local auto-parts store and get back on the road this weekend. When I'm searching on-line at NAPA, O'Reilly, Autozone, Advance etc, what year and model of Ford should I enter? For instance, would the fuel pump on a 1966 Thunderbird with a 428 work on a 1967 GT500? Or even better, if anyone has a part # for a fuel pump that fits, that would be a home run. Thanks for any help and guidance.

If it starts it's streetable.
Overkill is just enough.

Hello Roy, I found the post about the Carter M6905 fuel pump. The 1967 GT500 uses the fuel pump that has the fuel filter and canister that screws on to the bottom of the pump (picture attached). I would think a similar pump that fits the 428 on say, a Thunderbird would work. But hoping someone can confirm.

Yes definitely a 66 T-Bird Pump would work. Good luck with the new one and please test the real psi it will make just to make sure everything is ok, the quality sometimes is not perfect of the newer pumps you can buy. There are some nice pumps out there which are close to an original one but with better internals and for more hp. You also can check for the better versions of Carter Pumps as usually they have 2-3 versions of the same pump depending on your hp and use. But always make sure you dont need an fuel pressure regulator as some pumps require one.

All you need is a fe fuelpump that has the canister . T birds ,Fairlane, etc.  They will all work they just don't look like assemblyline which you don't care about for now.  You could of course use a regular carter pump and instead add a inline fuel filter between the fuelpump and carb as a alternative.

Thanks for your replies confirming an FE fuel pump will work and thoughts on the Carter fuel pumps and pressure. We have perfect fall weather and hope to be back on the road this weekend.

I'm posting the outcome of the fuel pump replacement, hopefully for the benefit of future searchers needing to replace their fuel pump.

        First, I need to point out that our car is very nice, but not nut-and-bolt concours so I did not feel the need to spend big $$ on a concours correct fuel pump.
        When searching the local auto-parts stores, the vehicle I entered for the search was a 1966 Thunderbird with the 428 engine.
        The first purchase was a Delphi fuel pump that worked well. A little too well. Following Kent's direction, I was able to take out a fuel pressure testing kit for the local O'Reilly's and thanks to Kent, discovered this pump was putting out nearly 16 psi. The specs are fuel pump pressure at 500 rpm, 352, 390 and 427 ... 4.5-6.5 psi. There was fuel coming out the top of the bowls and whew, the smell of the rich fuel mixture was overwhelming.
         The second purchase was a Carquest fuel pump part #3541143. When reading the description on the websites, it states that the Carquest pumps are engineered to the specs of the Carter fuel pumps. I had also read that if possible, get a fuel pump Hecho in Mexico and not one made in China. The Carquest was made in Mexico so I was optimistic. However, the psi was still a touch high putting out 8-8.5 psi.
         Not satisfied, I contacted our local speed shop here in Denver, On-Track Performance and he did some searching and said, "I can get you a Carter fuel pump. It will be here in a couple of days. It says it will deliver 5-6 psi." Getting pretty good at installing fuel pumps on a big block with power steering, I popped in the Carter fuel pump, held my breath and bingo - a steady 6 psi. The part number on the Carter fuel pump is M4008. It is also made in Mexico. Like the other three fuel pumps, it comes with the brass fitting to connect the hard fuel line and two gaskets. Searching on-line, the Carter M4008 is readily available from the likes of JEGS, Summit Racing, Rock Auto, etc for $40-$65. Let me repeat, this is not a concours correct fuel pump, but one that should have our car running smoothly and provide just the right amount of fuel pressure to keep those Holley dual fours happy in the coming years.

I thought I would mention that your initial purchase for the 66 T bird 428 fuel pump was defective in that the stock fuel pump for that engines needs would be 4-6 pounds also. I don't know of any 60's Ford engine that would operate properly with that high 16 lbs of pressure. I am glad you found something that works. That one at least looks rudimentary similar.  Too bad that there is not a closer to assemblyline looking lower price alternative for you and others with similar expectations. I have several assemblyline type 67 GT500 fuel pumps that it took a year and a half at considerable cost to get restored by the only guy I know that is doing them and consequently value them highly as I will not be going through that again .

@Bob I really would like to know which fuel pumps are the right ones for a 67 GT500 as I hear different stories. I think there were 2 different ones depending on the build date. But did really the very late build 67 GT500 had the CARTER logo instead of the CARburTER Logo?

What is for sure:
All pumps had the 5/16" inlet nipple.   

In the build sheet the part number is: C6OE 9350 C

The flange number on the 67 GT500 fuel pumps were 3909-S early and 4314-S for later 67 production.

All of the 1967 Shelby GT500 used the carter pump button top with the canister marked with red Autolite on a white canister not Fomoco

You have been listening. ;) You have the info correct. Yes the late 67 production engines used the pumps that had Carter instead of Car bure TER . The only caveat would be using the word "all" in reference to the fuel canister. Typical would be better . You know there could be that one guy. Of course the proof of the out of the ordinary for that specific car would be on that one guy.
