PE series pumps as Carter LP replacement...
Not sure if this is the right forum, but since LP issues are pretty much related to the 24 valve engines, figured I'd start here... This is a repost from info over on the TDR group, intended as a heads-up for guys looking to add/replace their existing Carter LP's with the PE series of pumps:<br><br>"After emailing PE about their pump line and asking a couple of tech questions regarding the bypass systems...they responded with this statement. <br><br>"Please excuse our long delay in getting back to you. We have been experiencing some problems with 4100, 4200 & 4300 pumps when used on the Dodge diesel. For the time being we are suspending sales of these pumps for this application until we have solved the problem. Please contact us in future (30-45 days) for an update." "<br><br>Word to the wise...

Re:PE series pumps as Carter LP replacement...
Unlike Carter (or Dodge or ???) at least they have recognized a problem with their product and have responded with saying they will correct it. Most pump folks would just say "its not intended for a diesel application...sorry". Or Dodge saying "problem...what problem??"<br><br>Looks like they are set on coming up with a real alternative for Cummins 24V Dodges. Hats off to PE pumps.<br><br>I bet when it gets corrected, it will be the pump that can go the distance. Its already pretty darn good from what I've read.

"Unlike Carter (or Dodge or ) at least they have recognized a problem with their product and have responded with saying they will correct it."<br><br>Not exactly true... Carter has made 6-8 running modifications to their pumps - those changes and upgrades have been posted several times on boards like this - and the later Carter pumps seem to be superior and longer lasting than the originals. It's pretty hard to get a good analysis of the "superiority" or inferiority of a VERY limited use of pumps like the PE's as compared to the stock Carters that come on EVERY stock 24 valve engine prior to '03 - there are not that many users of the PE pumps out there to make a valid comparison - I'm only aware of perhaps 6 guys using the PE's, and *2* of those have failed - a 33 percent failure rate isn't much to brag about, or anything to make me want to dump my Carter's for... <br><br>Plain fact is, that "failure-proof" lift pump STILL hasn't been discovered yet!

Wow! Sure hope my Holley Blue holds out long enough that the PE issue is fixed. Then again, the Holley might last a very long time. ;D<br><br>Chris

Re:PE series pumps as Carter LP replacement...
Is this Carter lift pump PE series the same as the Carter P4600HP 7 psi, P4601HP 15 psi with 3/8 inlet lines ? Or is it something all together different. Just checking before I make a comment. Thanks OverFueled

Re:PE series pumps as Carter LP replacement...
No, these pumps in question are manufactured by Product Engineering (PE). Specifically, the model most people use (including me) is the PE 4200 - rated at 270 gph and 18psi. Their website is www.productengr.com.<br><br>John

"Can you tell us exactly which Carter pump you are

Not sure what you're asking, but if you mean what model Carter *I* use as a pusher on my truck, it's a Carter 4600, 6-8 PSI, something like 100 GPH - sells for about $72 at Jegs - thay have a number of other models with other ratings and pricing as well.
I've had my setup pretty much since my truck was new, now have 12,800 miles and a year under the floorboards, about half of those towing our 5th wheel - not a whimper so far - you can see details over at the website pointer in my sig...
Some of us like to bash DC for their "stupidity" in their fuel delivery system - but so far, all the substitute pumps used to "improve" on the original, regardless of price or anticipated quality, have shown that they TOO fail, just like the Carters do - but hopefully, at some point we WILL come up with an ultimate, "bulletproof" pump - we just hafta keep experimenting!

Re:PE series pumps as Carter LP replacement...
There's nothing wrong with the Carter pumps used by Dodge, but rather the pump placement and fuel supply line design. It probably was never designed to be bolted to the crankcase of a diesel engine. Move the stock pump off the engine and put it back by the tank, on the frame, as far away from the VP44 as possible. This gets it away from the engine haet and vibration, and helps isolate it from the harmonics in the fuel line caused by the VP44. These are good little pumps which have been providing years of trouble free service in other applications.<br><br>Go to your local sewer district and talk the person who maintains pumps. There are tipically dozens and dozens of all different kinds of pumps in a sewer district. That person can tell you what REALLY has to be done about increasing pump life. Look at this web site http://www.pump-zone.com/pumpzone2.asp?ID=2, subscribe and read the magazine, then, after a while, you'll see what I'm talking about. I believe the solution to lift pump problems is in isolating and fixing the enviromental problems causing failure, rather than trying to find a better pump. The Carter is probably as good a pump as any other you'll find.

Re:PE series pumps as Carter LP replacement...
There is 5 pages of reading on the Stanadyne twin filter setup on the TDR site.<br><br>The thread site is Stanadyne System<br><br>It explains what was wanted and how it was accomplished. There are photos of the setup at this Readers Rigs album Setup Photos<br><br>If you click on "view other albums" up near the top you can see some shots of the components used and also some of the fuel module.<br><br>This particular setup gutted the stock fuel pickup module filter mesh screen. The 30 Micron prefilter/water seperator takes care of pre lift pump filtering. The mesh on the module is restrictive somewhat and it does nothing to remove water...which can be a major factor in electric lift pump failure.<br><br>There is alot of reading there but its worth it. Its also expensive as it cost over $500 for the total change plus lots of labor hours to fab brackets and "design" how it all goes together.<br><br>Just moving the lift pump is simpler and much cheaper. But filter access and super clean fuel are other benefits.
