Good To Hear!!!!

That is not cool. . Is there any other pump that even comes close to this one. . I have only heard good things about the PE4x00 until now.

I am about ready to buy another OEM LP from cummins mount them on the frame by the tank and just run them parallel with separate lines to the fuel filter, and a couple of one way flow fittings.



It's almost like our CTD's, DO NOT LIKE FUEL PUMPS!!!
 
Thus far, we are aware of two issues with the PE pumps:



1) A faulty run of cartridges has caused some early failures of the PE4200 and 4100 pumps. PE has corrected this problem.



2) Improper fuel system design has caused some early failures. PE pumps cannot be installed at the tank where water impregnation can occur. Coating with waterproof substances may prolong pump life, but overheating can occur. The pumps _must_ be installed where water contact on wet roads is minimal. These pumps also cannot be installed with a pre-filter.



PE has temporarily suspended diesel operations, and are undergoing some trials. They intend to test several configurations, however they feel that a system which mounts the pump forward under the hood, utilizing the stock lines from the tank, and -8 lines from lift pump through to the VP44 will work fine. Bench testing will occur, and PE will develop a recommendation of how their pumps should be used on our trucks to ensure maximum life. They want to be part of our merry little band of misfit dieselheads, and as such, we will be working closely with them over the next few weeks to ensure that we can develop a system which will meet everyone's needs.

Product Engineering specifically proscribes the use of pre-filters with their pumps. The pumps are designed to be able to pump sand laden gases and fuels (indeed they were tested this way), and all filtering must be done post-pump to prevent any further stresses on the pump.



Actually, in my experience, most well designed electrics, such as the Carters, Holleys and Aeromotives in use in the agricultural and trucking industry proscribe the use of pre-filters. Its too much strain on them to pull through a tight filter, then push through another tight filter.



Just a note for the guys who are building their own systems. Contact the manufacturer of the pump and ask what their specifications are vis-a-vis line sizes, draw lengths, pull height, and filtering requirements. All pumps are designed to operate within a specific set of parameters, and the chances are pretty good that the manufacturer knows more about their product than we do.

You said that

But I ordered my pump directly from PE and they told me to use a prefilter. ???

Weird. I talked to both John and Mike, and both told me not to use pre-filters on the PE pumps. John was especially adamant about no pre-filters.
