PPE pumps? Good? bad? only OK?

I've been digging around the net and a pump that shows up at a decent price often is the PPE pump.

includes the following features: provides up to 160 gallons per hour (Gph) fuel flow; fuel pressure is adjustable from 3 to 15 PSI; internal regulator is factory preset to 12 PSI; high flow 1/2 inch NPT inlet and outlet;

I don't see much mention of them on the forums.

Are they any good?

Worth the 250-sh bucks or not?

I'm not ponying up for an airdog, and raptor pumps are within my reach but waaayyy up at the top of my budget (around 400 bucks for a lift pump? Yipe!)

Walbro FRB5 was an option, but $150-160 to get it to my door has me weighing other options....
 
Isn't that stock Duramax pump? And have you looked at that hfp953 pump off of 98-02 cummins that's been talked about in the Lift pump alternatives thread? PPE would be interesting though...

At 1st glance it looks externally to be a gear type pump, which would not be a flow on fail setup, so one would have to incorporate a bypass path, is it self regulating ie it shuts off or slows flow if output of pump is more than demand.

Yes it has adjustable regulation 3-12 psi output, but if porting more back to suction side of pump which is where I assume it dumps excess fuel there is chance of building cavitation/heat/airreation

When speccing out fluid systems one should size the components to be efficient for the max flow the system needs are, more is better is not always the case.

Unless somebody has a monster IP out there 160 gph is not needed, some serious overkill going there, buying raptors-airdogs-PPEs with 3x over what we need is puzzling to me, especially from the 6.5 crowd that normally pinches pennies on things deemed to be too expensive like TMs "can't I build my own" folks laying down big green for lifts they are only partially using full output of :confused:
 
from what I was told...they are loud...

thats why I went with the Laing D5 Strong...ultra quiet and flow on fail...
 
Its the search for a reliable option, and that more pressure can increase charge pressure and performance. If I can buy a stock like one that lasts 1 year and I replace it every year or one that will last 10 years for 3 times the price AND it provides more pressure that will overcome snotty socks, filters getting dirty etc then all the better. Over Engineer everything!!

One would need to find out why yours are failing in one year if that is the case, my original lift lasted 8 years, suggesting that the engineering design was sufficient for most.

My Walbro has been running 3 years solo now and has yet to leave me stranded, parallel with the Heath h/o that never gets switched on.

That said this is the performance section and anytime 2 gear heads or Engineers work the same problem there will be different solutions, over engineer where practical is fine, but there is a point of diminished return of over engineering in terms of budget resources, physical size restraints etc.

There are multiple reasons to have a design that is good enough, hence my goal of 300rwhp tow machine, not drag strip, street, domination or salt flat record holder.

The question was PPE good, bad, or Ok.

IMO it's Ok, never been used on the 6.5 that I know of, & IMO more pump than one needs.

Over engineer if you must, I'll stick by my solution as it is working and working well thus far.
 
PPE pumps are not that reliable and they are real noisy.

I believe it is a "vane" type.

Which is not better.

Mine will be in parallel with the stocker, so there'll be a "built in" bypass...

Raptor is my first choice though, just have to find one that's affordable.....:rolleyes:
 
There are a number of people on this forum that have replaced stock type LPs numerous times. I swapped mine and it still worked, but the one I put in still worked but over time it lost its pressure (not acceptable to me). They may have 50% good reliability, some people get a decent one.

I agree the PPE is more than needed, thats why the FP953 is so attractive, a 14psi pump that will maintain 10psi at the IP for now less than an FRB5.
 
UNdestand all the comments about overkill with 95-100 gph pumps.

Especially in a truck like mine which is essentially a stock truck.

However, I also believe in "over building" when I'm going to pull a system apart to replace or install something.

I may never use the extra capacity, or I may need a good portion of it one day when/if I get around to some serious work. Not for a long while, but I'm a notorious tinkerer, no matter what I may say.

But I'd also rather have it and not use it than.....well, you know the rest.

:)
 
I also have bought a few stock type pumps. They are a joke.

The desire is more for PSI I think than GPH. Under 5 is too low. There are advantages to higher PSI. Any decent pump that can make 8-10psi at the IP after all the filters should have more GPH than we will ever need.

Kind of like my tires, I'm happy with the thought that they can hold more weight than I'd ever load on them.

Someone else needs to wire a 2ndary pump inline on a toggle to post results of the additional PSI on the fly. It makes my truck feel like I dropped 1500lbs by flipping the switch.

More fuel at same pedal position? Better atomization of injector spray? Touch more timing advance? Little of each? Don't know. All I know is running with PSI closer to 10 than PSI closer to 5 or under has this effect, each and everytime I flip the 2ndary pump on.

So while we may not need 10psi at the IP, it sure feels good. As GMCTD likes to say "Try it, you'll like it." :)
