2nd Gen Non-Engine/Transmission Is this Carter the Same as Our Carter

[Claw231]

I found this in the recent Jeg's Catalog that I received. I am wondering if this is the same lift pump we use, cause the price seems to be right. I was mainly looking at the last one listed, High Flow/High Pressure, 85. 99. See the pic for details.



Thanks,

Chris

I believe the bottom one you are refering to has the same ratings as a stock lift pump, but the threads are the wrong type,it has NPT versus the banjo bolt thread required for our lift pumps.

The top one is the one most of us running a pusher pump use!

They are different part numbers the one Dodge/Cummins is putting on is Part #(P74213) and I don't know what the difference is between the pumps. If it is just metric verses NPT that wouldn't be too much of a problem if you move the LP down to the frame. You would just have to use different fitting. So hopefully someone will bring some light to the subject if I'm wrong.

The other difference is the wiring. The one in the pic will have a place to attach wires to posts where the cummins one has the place to plug in the connection.



The bottom one has been used by several people that I know of, it fails just as often as the cummins counterpart. I have on in my shop right now and have been thinking about using it, just have to figure out a better way to attach the wiring so its more weather proof.

Another potential difference - and one nobody has answered yet, is that the LP's in our trucks circulate diesel fuel thru the motor itself for lubrication and cooling - something possible with the low volatility of diesel fuels, with little danger of explosion due to brush arcing - but that ALSO means wear particles - brushes, shaft bushings, etc, - are ultimately circulated on towards the engine - hopefully to be caught and held by the fuel filter.



The QUESTION IS, do the Carter pumps as displayed above ALSO circulate fuel thru the motor, since THEY are presumably more often used to pump gasoline instead of diesel fuel, and gasoline is far more volatile and provides no lube?

that's the one i intend to use for a rear mount after removing the front one. Banjo bolt v/s npt is a non issue in that case, and npt is actuall easier to deal with. wiring is another non problem.



good price, readily available spare summitracing also carries it same price.



half price of basically same pump you are overcharged 100% by chrylser and cummins.

Gary - I will pull the top off my 4601 when I get home in 10 days and let you know if it has the same internal bypass that the stock pump has. I have one of those that I am cutting apart to look at so the comparison should be easy.

Hey JR, that would be GREAT!



IF the standard Carters do NOT have the fuel circulation inside the motor as those in our trucks do, that eliminates a steady source of fuel contamination from internal motor wear - and I really doubt the supposed "lubrication and cooling" of our LP's is really all that great a factor in the real world
