Pusher Pump Installed!
Before fighting with a "0" on my fuel pressure gauge with a box install I decided to go ahead and install a pusher pump. I wasn't about to spend $600 on a fuel system, and based on my prior experiences there was only one pump I really trusted. I called up Summit Racing and ordered a Holley Blue pump along with all the necessary -6 AN stainless steel braided line and associated fittings. When it was all said and done I had everything to my door for less that $200.
The hardest part of the install was coming up with a place to install the pump under the truck. Thanks to the new hydroformed frames there are much fewer holes and windows in the frame, and drilling holes or welding is a no-no. I made a custom bracket that bolted to the frame through an existing hole and mounted the pump to that. I cut off the stock line using a pipe cutter right around the crossmember, and used a hard line compression fitting to adapt to the -6 SS Aeroquip line. I ran the -6 line from that adapter to the pump and from the pump to the stock lift pump. Once the lines were plumbed up I wired the pump using a factory 30A Chrysler relay and triggered the pump off the stock lift pump signal. I also included a quick disconnect plug down by the pump should I ever have to make an emergency swap. As I learned with my 2nd gen... always carry a spare lift pump!!
The results?
Before the pump install I averaged about 7.5 - 8 psi at idle, 6 psi at cruise, and could pull it down to 3.5-4 psi at WOT. With the new fuel pump installed my numbers jumped to 23psi at idle, 22 psi at cruise, and the lowest I could pull the pressure while hammering it was 18.5 psi. The pump is very quiet and I can only barely hear it at idle while sitting in the drivers seat. Outside the truck you can't hear it at all unless you're standing at the driver's door, and only then you have to listen for it and know it's there. For anyone with an aftermarket exhaust I really don't think you'd notice it at all. Driving down the road drowns out all the pump noise (what tiny bit there is at idle).
Overall I would say this fuel system is a great alternative to the other high priced pumps. The install takes a few hours (thanks Dad!), but the results are worth it! Now it's time to add some fuel

***UPDATE***
One year later the pump is still on the truck and still going strong. I have not experienced any issues with the pump, the lines, or the FP gauge in my year of bombing. This setup has about 20K miles on it, and it has been exposed to driving conditions ranging from drag racing at the strip to hours on end on an interstate while towing. It has seen temps ranging from 100 last summer to about 5 degrees this winter. The pump has become even quieter with age and is now unnoticeable even when standing next to the truck at idle. My max FP has actually increased a little to a max of 28 psi, and it will hold steady at ~15psi at WOT (my previous WOT pressures I noted were with less fueling, so don't compare directly). I do have a spare pump under my back seat, but if the current trend continues I won't need it for a long time!!! For the do-it-yourselfer I contend this setup works great... especially for the money!! If anyone is interested in a parts list let me know and I'll be happy to email it to you.

The blue is placed between the tank and the stock lift pump, and the fuel is run from the tank, through the blue, through the stock LP, through the stock filter canister, and up to the CP3.

Banshee, I think Scotty has a plate of some sort that allows you to bypass the stock lift pump - might want to look into that. Great to hear the update though, as I know some had questioned the reliability of the Holley pump.
Aren't you worried that you have TOO much fuel pressure? It seems a little excessive to be in the 20's.

Lightman,
The CP3s have a different internal system than a VP44 and are not prone to overpressurization. An internal diapgragm on the VPs would give way at around 30psi. Having looked at a cutaway of a CP3 I don't think the pressure is an issue. The single pump would probably be a simpler setup, but I'm not sure it would keep up with the demand I need. I suppose I'd just rather see 15 psi vs 2-3 psi at WOT.

btw - you can drill small holes in the frame without concern.
Keep them along the centerline of the vertical surface, never along a top or bottom horizontal. Keep them spaced apart.
I've got a hitch bolted onto the frame and it's fine...

Banshee - I don't know much about 2nd gens or vp44's. I've just heard concerns about too much on the 3rd gens not being a good thing. I don't have any links or exact quotes by any means, just curious if you were worried about that high of pressure or not. Most folks with FASS setups or otherwise aren't getting near the 28psi you had mentioned... Anyway, congrats on successfully running it for a year, that's certainly a step in the right direction!

I have 15k in three months with Scotty's Smart Fuel System (Holley Blue pump) and no issues. I have had many cold nights up in Colorado (down to minus high teens) and have never plugged. Have not seen any weather hotter than 80 yet.
The newest style Holley Blue is a good pump IMHO. Still wondering if I should carry a spare in the toolbox...
Max pressure of 15psi or so...

Although I don't have a 3rd Gen Dodge CTD, I too am running a Holley Fuel Pump,
although mine is the Red Pump installed the same way as "banshee's!" Thanks
son!
Mine is over a year old and I have not had any problems either.
Another DTR Member (Goody's-1Ton) is running the exact same system as "banshee"
and has had good luck with his too. I really like the Holley Pumps as you can buy them
at ANY "Advance Auto Parts Store", they come with a full one (1) year replacement
warranty and they seem to be very quiet. "banshee" and myself both had the high
dollar "PE 4200 Fuel Pumps" and had nothing but trouble with them!! I actually had two
of them @ $300.00 each and neither of them lasted over three (3) months! We tore
apart the PE 4200 and the Holley Red Pumps to examine them and internally the PE
looked as though it was made alot better than the Holley, but the PE's just DID NOT
hold up well!!

mine is in the shop getting tranny work done and the trannt guy said he would instll the lift pump for me while it is on the rack,so if i read this correctly just cut the fuel line between the tank and the stock lift pump and install the blue.you guys operate your with the key like i did on the dmax or did you run a pressure unit device.also did you install the regulator or jsut leave it out

I do love my set up. As with the Porterfield's I carry a spare one which at a $100 a pop is not that bad and the luck I have had with my first one I do not think I will need the spare. But the day I take it out of the truck is when the stuff will break down.
With the help of Banshee and John P the set up was really easy. The hardest part was getting the diesel smell off of my arms when I cut the fuel line. I see day to day at 50 degreess out side, 24 PSI on start up/idle and then at WOT I may see 17-18 PSI. I have plenty of fuel and it is apparent when my TST is on 7/7. I can proudly say, I am one of them.
One of the annoying diesels that puts out thick, stinky, dark smoke. ( not every day, I do not want to give us CTD owners a bad reputation.)

your 05 has the stock lift pump in the tank.

Jess:
Don is right, your "lift/supply pump" is now located in the in the fuel tank
where it is now technically "pushing" fuel up to the fuel filter canister and
from there up to the CP3 fuel pump. Prior to 2005, the lift pumps were
mounted next to the fuel filter canister.
Jess, you can mount the Holley Blue as you described or do it like we did
on my son's 2004 or Tom's 2003. We have mounted the Holley Blue Pump
on an aluminum plate on the INSIDE of the frame rail near the left front
wheel and tire. If you will look behind the left front wheel and tire you will
see an open hole that goes all the way through the frame. We pushed a
bolt through the hole and into the aluminum plate. We had pre-drilled two
holes in that plate and then mounted the Holley Blue onto the aluminum
plate. On the 2003 and 2004 trucks, Dodge had a combination rubber and
metal fuel line running from the fuel filter canister to the metal fuel line
under the truck. We took that out and fabricated stainless steel -6 Aeroquip
lines to run from the Holley Pump all the way to the CP3. We did not use the
regulator Jess as we didn't feel it was needed. "banshee" sees about 25-27
lbs of fuel pressure at idle now and I have never seen it go below 14-15 lbs.!
And yes, we wired it to be "key hot" but did use a relay also, probably similar
to what you and Buck have done on the Duramax.
BTW,.....what kind of transmission did you install in the 05'???
