Holly blue pump batman!
O.K. I got a holly blue pump and I want to do the install this weekend. I have some questions.
1. do I replace the whole fuel line from the tank to the lift pump or do I just "tap into" the existing line?
2. If I replace the whole fuel line do I need to remove the tank to do this?
3. does anyone who has done this have a pic or diagram to show exactly where is the best place to install the pump?
4. I can get ahold of 1\2 inch aluminum tubeing to use as a fuel line, should I use this since it is free or should I go with braided SS?
5. The install diagram from holly shows installing the supplied regulator between the filter and the "Carb", should I place it between the filter and the VP or between the pump and the stock LP since I will be leaving it in place?
6. does anyone know what type of connection I will need on the tank and at the stock LP?
Thanks,
Tengu

I never used a regulator on my Blue and it was fine with over 450 HP for over 50K.
A simple way to do this is to mount the Blue at the factory position by fabbing a bracket for it to fit. Diesel approved black rubber hose in the 3/8" or 1/2" depending on your fitting. Simple to tap into the existing line on the frame just under the driver...slip 3/8" hose over the hardline and clamp it.
You will find several different ways that folks have done this.
You can also do away with the banjo bolts and hardlines after the Blue but be wary of the Automotive Aeroquip red and blue fittings as they are highly restrictive. Just a heads up if you choose this route.

When you say "factory position" are you saying to do away with the factory LP and place it there? I was under the impression that the major flaw was the forward position of the LP. If not the Aeroquip red and blue fittings then what do you recomend?

If you are running stock power...then I would not be concerned with the aeroquip or other fittings to replace the hardlines. I would look at bigger banjo bolts.
I tested pumps at the tank and pusher pump combos and never had much success. The best was the Blue with hydraulic fittings and custom adapter from those to the metric thread of the VP and filter housing.
As I mentioned before...

Theres several different approaches.
This one worked best for me and this is where the Wildcat Max Flow Fuel System evolved from with our stock pump.
I am certain others will post their solution and or thoughts on this.

This is the pic of gsdog1's blue mounted along the frame infront of the fuel tank. The pics looking toward the back of the truck. In about a week a full kit will be available with everything needed to mount a blue in this location and upgrade all of the fuel lines.

Tengu:
I mounted my Holley Red Pump on a bracket on the
inside of the frame rail (drivers side) in line with the
support bracket that holds up your transfer case.
My son designed it by using a piece of "L" channel
steel/aluminum and then drilling holes to line up
with the stock bolts that hold up the transfer case
support.
I have -8 stainless steel braided line with Aeroquip
Fittings running from a 1/2" "pick-up" in the fuel tank
all the way up to the VP-44 Fuel Pump. In hindsight,
I think this may be "overkill" though! If you use
the bracket as I have, you can just cut your stock
fuel line, then "tap" into that fuel line with a "hard
line adapter" or "compression fitting" from Summit
or Jegs and then go into the Holley Pump with the
-8 and out of the Holley Pump with the -8. I have
a friend who also uses -6 and has not had a problem.
If you decide to go with a bigger pickup in your tank
(which I would not want to do again) you will have
to either: #1.) drop the fuel tank down or #2.) take
the bolts out of your bed and "jack" the bed up to get
to the plastic "cap" to the fuel. We competely removed
the "stock" pickup and replaced it with a "custom" 1/2"
aluminum pickup with a 90 degree -8 "Aeroquip" Elbow
coming out of the tank. One warning on doing this though..
...........make darn sure you cut that pickup long enough
to go completely through the stock plastic "fuel canister"
(or "BOMB" as I call it ) ALL THE WAY THROUGH
that canister and near the bottom of the tank!!!
Failure to do that will result in the pump "cavitating"
and sucking air causing a possible failure of your lift
pump or Holley!!
We also DID NOT use the Holley Regulator "Tengu."
I will try to get my son (banshee) to post the older
picture of his pump mounted on his 2001 so you
can see exactly what I mean. FYI,....I personally
like the stainless steel braided line under the truck.
It is tough and can take the dirt and water that can
get on the fuel lines etc., although many of the other
members just use the 1/2" rubber fuel line.
Hope this had helped you some. Send me a P.M. if
you have anymore questions or anything and if needed
I can send you my phone numbers!
Good luck Tengu!

This is a pure fallacy that has spread like wildfire around the 'net. What is important to a pump is the vertical distance between the inlet of the pump and the bottom of the tank pickup. The Carters, Holleys, and PE pumps that we've messed with all ask that the inlet not be higher than 1.5 ft above the bottom of the tank. Once the pump starts up, the siphon effect from the tank takes over and there is a constant stream of fuel supplied to the pump. We've measured the siphon effect on our trucks, and found it to be upwards of 120 GPH. This more supply than the VP44 could ever hope to burn, and as such, our lifts spend a large part of their time in internal bypass mode, which is non-pumping anyway.

Anyone who doubts what Rod is saying can do this.........
Get under your truck and disconnect the fuel line at almost
any point and see what happens! When we "cut" the
lines to install a "stainless steel braided" or rubber fuel
line for the various "pusher" pumps you better be "ready"
because I am here to tell you that the fuel is going to come
out of that line,......FAST and HEAVY!!
Good point Rod!!

If I'm correct, you can pick up a Holley Blue at the local Autozone, right? My PE pump is fine, I just want to have the blue as a back up pump and so when I ship the PE off to have the update done to it, my truck won't be down.

Since I am at stock power for now can I just put the blue pump in back near the tank and use the stock lines etc. Later I can go to the Max flow or similar system when I add more fueling capacity. This will give me the fuel pressure that I need now to be safe with the leasdt amount of hassle in the short term.

I put the blue into the frame rail just in front of the fuel tank. I replaced the stock hardline-hose combo from the tank to the blue with a 10mm rubber hose. (Because my quick connect fitting at the tank wasn't tight any more and let air in- not good)
From the blue to the fuel filter I use 12mm rubber hose with a homemade fitting to the fuel filter. From the fuel filter to the VP44 I use a part of the wildcat max flow system. (Thanks Rod for sending me just the right parts and not selling me a complete kit I didn't need)
The holley blue is powered by a relais that is switched by the power on the stock LP harness.
A little tweaking of hte regulator in the blue gave me 18-19psi at idle and 16 at WOT.
This has been running like that for about 60 000 kms now. So I can say it works for me.
I made a little protector cover for the holley blue from aluminium sheet metal to avoid debrisbeing flung at it.

It is targeted for the trucks under 600 Hp.
Due to the fact that I am not a site sponsor I do not want to say anything more at this time and get myself in trouble.

What a nice smell 25 gallons of diesel on an unsealed concrete floor. Actually I may not have admitted that til now. LOL I had the hose aimed up and it stopped, then I came back to a lovely fountain.
The stock lift pump if fed properly and has good stock pressures will do real good when fed with the Wildcat Max Flow and the banjo bolts are dropped.
It is imperative to have a good stock pump! Some of the folks running over 450HP have 10's of thousands of miles on their trucks with a stock pump and safe fuel pressures.
