Two new HPFP and both leaking from front seal

[08BIGRIG]

And I still have 15 psi at the air dog and 10 at the return regulator.

Glad to see you got it figured out! Sounds like its been a major PITA for you.

Now go drive the wheels off that sucker!!! What all did you end up doing?

 

[madman1234509]

So what did you do to fix it

 

[08BIGRIG]

Got a new pump. This time it's a Siemens OEM pump that was made in Germany. Not remand here in the US. Truck even idels differently with this pump. I have another good pump here that I just recently bought from one of my homies on here as well. Things are finally going the way it should.

Well its nice that your truck is running right, but it sucks that you weren't able to get the "new" pump to stop leaking. Sounds like we need to get a better seal in them before there installed in our trucks. Which is complete horse sh!t to get a new pump and have to worry about it leaking.

Did you take a pic of the tag?

Where did you source the Siemens pump from?

 

[08BIGRIG]

I got the pump from an independent guy. I am seeing if I can get more but it looks doubtful.

And I also got a continental pump with the seal like the original pumps from a buddy.

I was told on another thread that Continental bought out Seimens so it makes sense to have the Continental seal. I have been trying to make sense of the numbers if you happen to have that.

I know this is bringing up an old thread, but I had a few questions....
If you disconnect the wiring off of a K16 does it go no fuel (unlike the CP3s which are full fuel if you disconnect the wiring)?
For those of you who run an unregulated return, have you ever checked to see how much return you are getting? If I am understanding how the K16 works in an unregulated return system, you would expect to get minimal return fuel because the VCV will keep a lot of fuel from ever entering into the pump, right?

With out a regulated return you will blow the seal out of the front on the pump after a few miles the feed has to be regulated at some point

I am running Marty's kit so input is regulated. Would that not be sufficient?

just regulate the feed to 10psi and call it done. ive been running it this way for 35k and no issues, and unregulated return. the only thing I did different is I went way over kill with regulating and gauges to make sure I didn't over pressurize the pump. I set the fuelab to approx. 12psi, then it feed to a aeromotive regulator set to 10 psi with a gauge on it under the truck, then used the machined block out of elites fuel bowl delete kit on top of the engine and put a gauge there also to verify it was 10psi going into the pump. wanted to take a pressure reading as close as I could to the HPFP

If you unplug it it will not run.

The return does not have to be regulated. But yes the feed does.

Over 10 psi feed pressure, like Craig says will eventually start pushing fuel past the front seal.

 

[Morgan@Midwest Diesel & Auto]

Brett, did they get it to run?

It is running but with same symptoms. They are going over the eclectical side of things very closely now with IDS but they had already reset the PCM with Snap On.

You're selling the fuel lab kits with the dodge pumps that are set at 18psi, wouldn't that be to much then? Just curious since over 10 will push fuel past the seal. I know you run unregulated returns so does that compensate for the 18lbs feed pressure.
