'67 "A" code Autolite carb
« on: June 12, 2015, 01:20:23 AM »
Is the original Autolite carb on a '67 "A" code a 4100 or 4300?  The 4300 carbs I've seen have the fuel inlet on the left side(driver's view) which doesn't line up with the pump to carb steel fuel line....whereas the 4100 inlet is on the right side, which does.

I believe 4300's were introduced in 1968.

Some early 67s had 4100s but most had 4300s. The were a lot of problems with the 4300 so many cars were changed.

The best part about a 4300 is that it's easy to switch it out for a 4100.   ;D

    I'm not aware of any 4100's used for 1967, with the exception of the few 67' hipo's (489 units). 2100's were the main stay for the 2v cars and 4300's were used for the small block 4v cars,  "A" codes in 67-68 . The same goes for Cougars and I think some of the part numbers cross over between the two lines.   Big blocks received the Holley 4150 carbs that I believe were rated around 735cfm??

     I have also heard of issues with the 4300's including "flat spots" in acceleration. But, some builders have supposedly worked these issues out. Pony carbs was one that claimed this but I do not know of anyone to back this up.. (and they have been out of business for sometime now). I have numerous Mustang specific 4300's as cores because face it, many folks want the original set-up now a days and they seem to be holding their value probably for this reason. I'm sure a lot of folks in the day replaced the 4300's with over the counter Holley's (600 cfm's)... Hope this helps

How does the pump to carb fuel line attach....the only fuel line I see available for a '67 289 is the one that will end up lined up with the wrong side of the 4300 carb, which has the inlet on the opposite side.  I have a 4300 for my '67 A code, but don't see how to get from the end of the fuel line to the carb inlet.

4300's have fuel inlet on the drivers side of the carburetor, behind the distributor. The fuel line runs on the drivers side of the distributor (LH drive cars) , behind the distributor then angles up with a bulb or "barb" on the end of the tube. ( The earlier 66 style 4100's have the fuel inlet on the passengers side, same fuel line that the 1967, 2100 [2-barrels] used) I'm looking right now at a A-code 4300 for a 67 289 and I know I have seen the fuel line available reproduction before, but I cannot remember where right now.

How does the pump to carb fuel line attach....the only fuel line I see available for a '67 289 is the one that will end up lined up with the wrong side of the 4300 carb, which has the inlet on the opposite side.  I have a 4300 for my '67 A code, but don't see how to get from the end of the fuel line to the carb inlet. 

On the fuel pump, it connects with a fitting. On the Carb side, there is a short piece of 5/16" fuel line and two pinch clamps, and connects to a carb-mounted Fuel Filter.

Hard for me to find pics on Google of a 67' "A" code engine right now. 1967 -68 would have been no doubt identical but since this is a concourse site I assume you only want 100% correct info for the 67' A code. I have however, found a pic of a 68' J code. My opinion is that this would be the same gas line you need. In 68' it would have been a 302 with a 4300 carb (J code). I'm sure one of the members on this site has a pic of a survivor car (engine) for your reference. The major parts suppliers should have what you need? Try Virginia Mustang or NPD,etc. Maybe even West coast Cougars could help since the engines were pretty much interchangeable during these years. Take a look at the pic supplied. It appears the 4300 used an inline filter and small section of hose between the carb and fuel line. You could also try and move this post to the 67-68 section (or start a new?) where you could get a more definite result and quicker response. Hope this helps

That does appear to be the pump to carb line  I need...I didn't see that available under '67 289 fuel line...I'll check under '68 and see if I find it there.  Thanks for the picture...it's what I needed.  My 4300 is dated correctly for my car so I'll try to use it...although I've read that it's a problem carb..

Before I install the correct('68 style)pump to carb for the 4300.....am I correct that an April '67 San Jose built 289 A code would in fact have had a 4300?  The carb is dated properly for the car, I don't have enough previous owner history to know it is original to  the car.

Yes, starting in 1967, Ford installed Autolite 4300 carburetors on all 'A' code or 289-4V engines.

Note that there are 4 different numbered 4300 carburetors on a 1967 Mustang (or Cougar). 49 state automatic and 3/4 speed manual transmissions, and California emissions automatic and 3/4 speed manual transmissions.

As mentioned previously, K code or 1967 289HiPo's still got Autolite 4100 carburetors.
Shelby's GT500 all trans = Holleys
GT350 w/4 speed = Holley
GT350 w/auto = Autolite 4100

krelboyne, is it also correct to say that a cougar fuel line is identical to a Mustang for this year/application?? That's what I have always found to be true.

Also, socalgt, what trans is original to your car and what is the stamping/tag on your carb?? I  believe that states with emissions (California) carbs had "brass" tags while other carbs had the standard aluminum tags. Looks like your tag is indeed brass. I know this holds true for earlier 4100's and I think it's the same for 4300's.

Yep, so C7DFD is for a 1967 Mustang ,289, AT with emissions. If your car is an auto than that is the exact carb for you! 8)
