So I am going to be dumb here now, IF I understand right, I have a 98.5 24v CTD and IF I would stay with an AirDog 100 I wouldnt have to drop the tank to change the pickup tube? I DO NOT have a tank LP, mine is still stock mounted.

 

My understanding so far on the airdog is that for the 100 gpm you can use the OEM plumbin and for the 159 you will need to change the pickup tube as well as the lines ????????????

any year that has the OEM lift pump in the tank should be removed and replaced with a new pickup tube

check this info out it will help ya


The first step in this process is to disconnect the existing fuel line connected to the fuel tank pickup tube; this can be a challenge if you have never done it before as most of the work is done by feel since you cannot see the actual tank module, I have found 2 different ways to get to the feed line pickup, first is to lay under the truck and reach up and on top of the tank you will feel it or if your truck isn’t equipped with wheel well liners then you can go in from inside the wheel well, if you choose this method it will be easier to remove the left rear wheel and support the truck with a rated jack stand for safety. The line you are after is the one toward the rear of the truck as you can see in this picture, notice how the blue retention clip is inside the plastic fuel line connector. The trick here is to squeeze the two tabs together as to release the clip from the shoulders of the pickup tube inlet, squeeze and pull the connector off, the blue retention clip will stay with the pickup tube inlet , then you simply pull the retention clip one side at a time towards you till it actually inverts itself, do this to both halves of the clip and it will slide right off.

 

Here is some intank pump info to help ya understand whats goin on there


I had the unfortunate pleasure of replacing an intank pump on my friends 99 Dodge/Cummins

Needless to say my opinion of this bandaid of a fix that DC came up with is even more rediculis than the OEM carter pump mounted on the Cummins.

This pump is 4 months old and has already failed, at idle the pump delivers 15 psi but the slightest touch of the throttle yeilds a woppin 4-5 psi, WOT will pull it to ZERO....................So the owner of the truck purchased a after market frame mounted pump from a reputable dealer and we are off to the races with the install.

The bed of the truck was full of stuff so we opted to drop the tank although he had 3/4 full. The use of a good floor jack worked well for this however we still had to put the tank on the shop floor to get clearence to pull the intank pump.Once the tank was on the floor the job was very easy from there.

Following is a picture of the intank pump along side of the OEM sendor/pickup tube combo, the intank pump/ level sendor is on the left, yes thats the actual pump at the base of the unit there

 

I think Whitmore is right, if you have bouncing boobies...er...in tank lift pump, then you need a draw straw.
Since mine is an 04.5 with the stock pump on the filter canister, I can just hook my 100 up to the stock pick up and bypass the bouncing boobies...er...pump completely.

 

from 03 and up the OEM lift pump is mounted to the back side of the OEM filter canister......................this pump will be removed and the outlet line of the Airdog will plumb in there

Damn......now I want an Airdog so I can do a good write up with pics

Anybody around me here in Wyo that wants to do the Airdog please get with me so we can get some good coverage on how to do this

I have the heated shop and camera ready to go

 

IF I dont plan to make any major HP increases outside of maybe getting an Edge Juice/Attitude down the road is there any need to get an AirDog 150 or will the 100 be well suited to handle those needs? Like Solarwarp said about dropping the tank, I am limited on hands to help and if I can get by not having to drop the tank to save me a BIG step I would prefer to do so. From what I gather from the posts here the AD100 would allow me to reuse my stock pickup tube since I DONT have an In-Tank LP and I can reuse the stock fuel lines as well. Are there any other changes that need to be done AT the tank for MY application as any of you know of?

 

IMHO..the 100 will do ya just fine for what yer after ...................... I dont think ya will need any other mods

do you have a fuel pressure gage??????

 

Where are you at in Wyo? I live in Ogden UT, about 80 miles from Evanston.
I have an AD 100 and vent tank mod kit waiting on me to get home. And it's colder than a witch's nipple in a brass bra in UT right now.

 

Shoshoni Wyo.....dead center of the state

worth the drive up for ya??????????

 

That's a long ways this time of year in a 2WD dually. I'll be sure to take lots of pics when I do mine.
I can work on the truck at the base auto hobby shop, but I'm not sure if they'll let me put my truck on the post lift, and I think they have a rule against dropping the gas tank out of a car inthe shop. Not sure about diesel though...
