Glacier Diesel Power Kit + 2 micron Filter Kit

[99Supercab]

this pump has me interested. . what are the threads on the in/out on that walbro pump??



i have access to loads of -6 thru -12 hose scraps from work so i can use that for my plumbing [-10 pickup to strainer/filter, pump, -8 to stock filter, -8 to boost ref regulator, -8 to 2u filter, -8 or -6 to cp3 inlet. . ]

Nick, do a search here, on www.dieseltruckresource.com, and on www.cumminsforum.com and you`ll find all the info you ever wanted to know about the Walbro pumps.

Thats the funny thing, There is no set models that have the apps under the battery or on the engine... .

I think most 03-04 sticks have it under battery, But then again I have saw an 04 6-spd with it on the motor.

6 in one, half dozen in the other

what is "apps"?

 

[Tomeygun]

what is "apps"?

Accelerator pedal position sensor...

Accelerator pedal position sensor...

Yeah and those sorry suckers from Dodge put mine on the engine! Now I have to wait for the other kit to come out!

Hey Tomey,



Did you get the new kit on this weekend? Just curious on any preliminary results...

Hey Tomey,



Did you get the new kit on this weekend? Just curious on any preliminary results...

sadly no, I am missing one part I needed to do the install (not a Glacier part, a part that I need in my custom fuel system... )



It will be here tomorrow. Should have been here friday, But the darn company forgot to UPS it... ARG!!!!!

 

[Tomeygun]

I did half the install today...



I ran the return line and installed the bypass valve. . IT works great, I regulated down to 15 psi (just to test) - I will up it to 25 psi when I ge the pump on...



Till then. .

I have had this kit in my truck and I love it. It took me about 2 hours to put in. I tried to talk other people into buying this. My fass just didn't work out and I went with this system and have had no problems. And to all the Holly pump lovers who see the above pictures and have talked bad about or been afraid of this walbro pump take a good look at it because it looks just like a Holly pump without the sticker. O wait I read that walbro makes Hollys pumps as well as other companys pumps that place a sticker on them with there name on it.

SOOO.....



I got the pump on today. With the the weakest shim I have 13psi at idle. .



AND let me let ya, When I say this thing is quiet, I mean it. I mean so quiet that I had to open the fuel door and listen for the fuel rushing back in the tank to see if it was running...



So far the walbro is winning against my Dpp/Fass pump based upon volume in cab. But the true test will be when the truck is really pumping the HP. I honestly dont mind the noise, But the PSI dropping to 12 got my attention. My intent is to prove a winner based upon psi that can be held when my truck is on the 600hp setting.



Testing coming soon!



I plan on using the 15lb spring and the 40thou shim. Till later... ... .....

 

[lmills]

how much is your psi at idle??

 

[Tomeygun]

how much is your psi at idle??

now - 13psi



Planned with the shims - 25-27

I was one of the "original" Walbro installers. This was before Rich started his new company. I'm planning on running his bypass valve or possibly a regulator in the future. Currently, I have a direct bypass from the cp3inlet to the return side in a loop using 5/16" fuel line as a restriction. My pressure sender is in this line. I've been running this pump for 9000 miles and since the install, I've added a pre-pump filter and a post-stock pump 1 micron filter. Thru 3 filters, I still see 20psi at idle, 19psi while cruising and about 12psi at wot. The lower number is why I'm contemplating using his valve or a regulator. This pump has so far, been very quiet, very consistent and downright inexpensive, compared to the alternative. I've got less than $250 in my "homemade" setup...

I got in this morning and still can't believe how quiet... I mean like virtualy silent

AMassaro, I don't think the 12psi at WOT is anything to be concerned about. According to some posts that I've been following on other threads, that is right in line with what Bosch wants to see feeding the CP3. Here is a clipping from one post on another forum that discusses this... .


yes I did read the info on the CP3 from the internet. But not satisified with that, I sent an Email to Bosch. With no response from them towards my email. I called their European 1800 number and talked to their tech line. Lots of valuable info about how the pump works and the increase of pressure.
But values were vague.
As for inlet pressures 0 psi will suffice as long as the volume is with in spec of in or around 40-60gph. But I was informed that running 10-14psi is normal operating of the CP3 in our application. Further to that any increase in the head pressure would result in a higher rail pressure. That was stright form their Tech line.

As for how and why it effects our engines well it is pretty long and drawn out. Needless to say the truck runs at preset settings, those settings are not set hard in the way you would think. Ie 5000psi @ idle may actually be 6000psi. To many variances to account for.

With the higher head pressure the CP3 is able to get to it's rail pressure quicker. Hence better response and ability through out all operating parameters.

On a side note to this the CP3 family of pumps is used in many different applications from small cars to heavy trucks. They all share the same common components but are all spec'd to run at different sustained flows and pressures.


The poster states that increasing the lift pump PSI also increases rail pressures according to Bosch. I'm not sure about that part, which is interesting. But, 12psi at WOT seems to be nothing to worry about.

I'm not sure what my dual-return-line Walbro setup is running at WOT right now, but I'm installing an in-cab fuel pressure gauge this weekend and will have that information soon. After 2,500 miles of use I can't say enough good things about the Walbro pump.

I'm not sure what my dual-return-line Walbro setup is running at WOT right now,

Dual return line?



why more than one?

 

[JasonCzerak]

My main point in a new fuel system is the Air sperator deal.



Other then FASS, can something like this be customized in?

 

[MFalkinham]

Dual return line?

why more than one?

Like AMassaro, I was one of the early Walbro installers before the Glacier kits came along. During my research, I saw posts about the possibility of overpowering the stock fuel return line with the Walbro bypass. As a precaution, I added a second 3/16" return line from the CP3 to the fuel tank.

I can't say for sure that it has helped, but it hasn't hurt anything either. The only difference I've seen is that my CP3 fuel pressure at idle (13-14psi) is lower than other Walbros have due to the 2nd return. But I'm more interested in the flow rate the Walbro provides than the PSI. To me, as long as the stock CP3 is well fed with a solid flow of fuel, having a high PSI doesn't mean a whole lot. Bosch seems to confirm that per my earlier post... ...

Ahhh... I see. I am running the same - one added fuel return with regulator inline (from glacier) and the factory one...



I like the sound the fuel pushing back into the tanks, its cool... .

So how is the walbro working for that modded CP3? is it able to keep up? I am using you as my guinea pig, if it works for you w/o issues then it will probably work fine for me too.

I had my in cab FP gauge out because I was measuring it underhood when testing the CP3 - So I need to get it back in cab...



But so far I have notice at least as much performance - More I suspect. The spoolup seems better for some reason, and I have not even cranked up the PSI yet...



Dont worry, if theres one thing I love, its a good head-to-head test!!



RESULTS to follow...
