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.

but I did suggest the 3/8" line from the tank.




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 ???

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

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

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.

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

Good information here. How do you make a favorite thread so I can keep track of this?

I'm wondering the same thing. Replacing my fuel pump and can't seem to find an adapter that will work????
