Need 440 Fuel Pump - 02/27/09 04:18 PM
Who sells the correct fuel pump for a 1969 440 375hp engine? The OE Chrysler part number was 3004107.

Go to your local auto parts store.

I've tried. They show the 383 but not the 440 with the correct threaded fitting for the metal fuel line.

Others, far more knowledgeable than myself should chime in here, but I went to O'Reillys.

See if you can find a Carter #M4845. It has a 3/8" inlet with the correct angle between the inlet and outlet for your stock fuel line to the vapor separator.

If your looking for a "real" one,try ebay #400031828989,although I thought Carter reproduced one that is very close to this original design

You can also bolt on a Hemi filter. That's what I had on mine until I knew better.

Thanks! The picture looks like the pump I'm trying to find.

I don't know what HE meant, but I also bought the Hemi pump and was about to use it until several knowledgable people told me it'd have way too much pressure for my 6 Pack. It was a carter that came from Chrysler and was rated at 8.7 PSI; I was told that anything over 5-6PSI was too much.
I ended up using the M4845 pictured above.

Would that be too much for a Holley??

Someone told me it was wrong. It worked fine on my U code, but obviouly not was not aesthetically correct.

I would imagine so (after all the 6 pack centre carb is basically half a 4150), but I have no relevant direct experience.

I run the Hemi 120gph pump 8.5 psi max with no regulator on a six pack and it works great. Pulls hard through all the gears. At the worst you would need to add a regulator, if i did that I would set it at 7.5 psi, as far as the 120 gph the engine won't use more fuel than it needs but it certainly will run bad if it doesn't get enough.
I used some of the other Carter pumps and my engine layed over in 3rd and 4th gear and ran like crap, didn't pull the way it should have. The other pumps discussed are prob fine for stock rebuilds, any modifications and I would use the Hemi pump. Just my

I use a Hemi type pump on mine but it has a max of 7.5 psi pressure. Carter has several. The #4589 pump has a 3/8" inlet. I use the 3/8" Hemi fuel line from the tank and am planning to switch over to the 6.5 psi #4845 from my current 7.5 psi Hemi type pump. You can get whatever you want from Summit. It's not a bad deal except for the mandatory $9.00 handling charge...or is it more now? Check out the available Carter pumps on the link below. Click on the part number for the specs.

The 6.5 flows 80gph the 8.5 psi flows 120gph. My car wanted the extra volume.

The 4845 has a 120gph max 6.5 psi rating. Bob K (Mr. Sixpack) told me that anything over 7 psi would blow past the needles and seats on the 440-6's. If you are not worried about concours judging, I would get the 4845 if you have a 5/16" fuel line because you can get the fittings for either 3/8" or 5/16" inlet. The OE type #4589 also has a 120gph max 6.5 psi rating but it has a 3/8" inlet. You could slip a 5/16" fuel line over it with a little lubrication if you have a 5/16 fuel line. You may have to get a fresh hose for ease of installation.

Re: Need 440 Fuel Pump - 03/04/09 01:26 AM
I have no issues with the 8.5 psi pump the part number is 4862 you might be right on the flow for the part you mentioned there is another version that only flows 80gph. Check it at Mancini. I have no issues with the 8.5 psi not blowing past the seat 6 pack runs strong with no issues. Real world...if there was an issue all you need is a reg after the pump set it to 7.5 psi. A good six pack will run out of steam with the lower psi IMO.

Re: Need 440 Fuel Pump - 03/04/09 02:12 AM
I have no issues with the 8.5 working on your sixpack. I wish mine was running strong right now. However, it seems like GEETEEX is looking for a stock appearing replacement because he mentioned the p/n? It's a 4 bbl and probably not a race car. Do you really think he needs to try a high pressure non-OE pump when the 6.5 at 120 gph will work fine and looks like the one he's trying to find? I'm just trying to answer his question about where to find a correct appearing pump. I do not believe it's a matter of maximum performance...but I did suggest the 3/8" line from the tank. By the way, I had the Carter 5903 7.5 psi on this car. No problems at 120mph in the 1/4.

Depends on what you want, on the street you would never know the difference because you would not be doing 1/4 mile passes.
On the track if you have 6.5 at launch you could easily drop 2psi on top end which would not be enough. Depends on your combo and needs, just relating my experience, the hemi race pump works for me on the street and track with no issues.

... several people told me the same to stay away from the hemi race pump, after going through 3 diff carter 440 pumps I installed the hemi race pump and my issues were solved. I could have saved some $$ by buying the right pump in the first place. Honestly I think most would not know that they are fuel starved on top end because they don't work their cars hard enough to find out. If you do I think the choice is clear.

JD , his car is it's a GTX would have the 3/8 line on it from the factory , it makes ZERO sense why chrysler left the 5/16 line on A12 cars ???
Posted By: GeeTeeX
Re: Need 440 Fuel Pump - 03/04/09 03:27 PM
Yes this car is just a stock 69' GTX, 440 375hp with the carter 4 BBL carburetor. It had the original stock type fuel pump on it and started leaking. That's why I wanted to find another OE type pump to simply bolt up to the fuel line etc. As suggested I found a carter M4845 pump and should have it by Friday.

Just to be clear; the people telling me (and JD) are racing thier 440-6's in Pure Stock, so they definitely KNOW if they don't have enough flow. Most of these motors are pushing well over 400hp at the rear wheels.
As I said; my car isn't even running yet so I guess time will tell, but I was told by several people that the 8.9 PSI pump will cause me problems. Also, since the car is stock appearing, I don't want to run a regulator.
Don't get me wrong; I'm sure your setup works well for you, but I don't think that a healthy 440-6 NEEDS the 8.9PSI pump to run properly....even up to the 450-500 gross flywheel hp level.
cheers,
Dave

Re: Need 440 Fuel Pump - 03/04/09 04:10 PM
Oh, I just remembered another thing; my engine builder buddy was giving me a hand the other day and he took my fuel pump and checked it for play. He said sometimes the play is excessive and then you lose serious output from the pump.....just a thought

Re: Need 440 Fuel Pump - 03/04/09 04:23 PM
My 440 is a stroked 493 540 solid lift cam with Modern Cylinder Heads ported Stealth heads it needed the xtra volume. The other pumps fell off, and the pump puts out a max 8.5 that doesnt mean you get that psi at idle. My six pack is jetted pretty fat with a 50cc accelerator pump 3/8 line.It needed the xtra volume, the other pumps couldn't keep up and were a waste of money.

Re: Need 440 Fuel Pump - 07/30/09 05:29 PM
I'm confused. My FSM calls out a Carter MS-4434S fuel pump for 440 H.P. It says the 4589 is for 383/440. I ordered a Carter 4434, and am installing it now, and it has a 3/8" inlet, but the threaded outlet is smaller than the 5/16" line to the vapor separator that I have. Is this wrong, or is there supposed to be an adapter?

I had a Carter street pump on my six pack set up and had trouble with it pushing past the needle valve. I put a fuel press gauge on it and with just the starter spinning the motor it read 9 psi. I went with a stock factory type six pack pump and so far so good. My motor puts about 380 HP to the rear wheels and while on the floor dyno the tech said it showed no signs of leaning out or starvation.

I did the same thing decades ago, playing with various pumps, Carter, Holley, and continue to do the same with customers and people building 6 pack motors,.....skip the rest, go straight for the race Carters,......on my 440/6 motors I run the Carter M4862 8.5 psi, and I've been running the Race Carter M6270 on my Challenger T/A 340/6 for about 20 years, after going thru countless Holleys and other Carters that can't keep up with demand in high RPM/ high GPM demands,.....but I allways swap out the rubber tipped needle seats to the Holley all steel needle seat assemblies,(costs about $50 for 3) as a high pressure pump can load a stock needle seat,causing it to stick in the "closed" position, and cause a starvation problem,(empty bowl) I've never run a regulator at all in 30 years of running basically nothing but 6 paks, never had one "blow fuel" past the seats, had Stock seats get stuck from overpressure or debri, but have allways gotten in the habit of tossing the stock seats everytime to avoid problems
