Today we're going to be installing the new updated AirDog in-tank fuel pump module upgrade
kit for the quick connect hoses from AirDog. And I really wanted to go over the fuel module
with the in-tank pump and this is on the '98 trucks to current. If they've had the modular
upgrade done or if it's an '05 or lighter truck. This is exactly what you're going to
see when you pull it out of the tank. There may be different variations to it from different
suppliers just depending on where you get it from, but they're all going to be basically
the same.
The basics of the canister, we have so many questions on this. This is probably one of
the biggest tech calls that we get. Some of the basics of the canister, we'll start up
top here. The pressure side is always the larger of the two. Smaller the two lines here,
those are both quick connects. That's your return side. And then you've got in the middle
there, you've got your electrical portion that hooks up for your fuel level sensor.
And actually the power to the pump and then a fuel vent here. This gray tower is a fuel
vent and then this is an unused port and we're actually going to use it back and I'll get
into more of that.
The pump itself is down here in the fuel bowl in the canister. This is, it is held by three
black tabs. You can see those through the canister there and we're actually to remove
this pump. We're going to remove this pump out a tank to give us more volume to the canister,
more fuel volume there to the canister to draw from. We're actually just going to cut
these black plastic tabs to get the pump out of there and that'll allow the pump to come
out.
Now this module has some spring to it. When it goes into the fuel tank, it actually compresses.
When you put it into the tank, you actually compress it and then put your locking ring
back on to it. So you have flex between the top of the canister and here at the T-block
and then it's rigid from the bottom of this T to end of the cancer. Now that's just a
basic operation of how this operates. Fuel pumps, out of the pump, to the pressure side.
That's just a basic operation of the fuel module.
There's ways to modify this module. If you put a stock lift pump on the truck and find
out that you got the pump in the tank and what do you do? It's the weekend. How am I
going to get my truck up and running? You can modify this canister. We're going to get
into that at the end of this video after we've actually done this install. But the at first
I wanted to give everybody a really good look at this fuel module and now we're going to
get started installing the AirDog in-tank module upgrade.
Okay. To start our installation of the in-tank fuel modular upgrade kit, what we've done
first is we have removed the pump from the canister. And here's a shot of the canister
with fuel pump removed. All you that you need to do, to do that is disconnect the wiring
to it. Cut these black plastic tabs away. There's three of them there, cut those away.
Then simply lift the pump out. Here's a shot of the pump. That was pretty dirty, goes to
something be said for fuel quality here folks. And I'm also going to take just a minute to
talk about this canister.
For the guys that have found out that they had an anti fuel module and they mounted a
pump up on the bar, can't get any fuel to it. They call in here all the time. How can
I modify this and get my truck up and running? I've got to get my truck up and running now.
So here's going to be a quick crash course as to how you do that. Cut and remove the
fuel pump out of the cancer. Just like normal, no problems there.
Here there's a T block here for the pressure side. What you'll need to do is remove the
cap from the T block and inside there you'll find a check valve. That check valve is nothing
more than this little piece of plastic and it is down inside of the barrel of this canister.
When we were talking about doing the in-tank upgrade, if you do not get the in-tank module,
if you're on the side of the road, you need to get this going real quick. We talked about
taking this [inaudible 00:04:38] flat here and one thing I forgot to tell you is you
actually have to cut this spring check ball out of here as well. The closure valve. Once
you get that out of there, you will have a no restriction pick up here that will help
to get you up and running.
The spring assembly. Everything attached. Once you remove it
and you can put the assembly back together, snap it back together and that'll give you
a no restriction way to draw out of this module. All you would need to do here is simply attach
a piece of fuel grade hose, take it to the bottom of the canister, cut it eighth of an
inch off the bottom of the canister and you're up and going. Apply it back to the suction
side and make sure you still have no restrictions and that'll get you up and going.
And now as far as back to our install, now what we're going to do is we're going to find
a surface on the top of the module to begin mounting our bulkhead fitting. And we're actually
going to start here with the unused vent hole that is already on the canister. It just has
a rubber plug over top of it. And what we'll do is we'll remove the rubber plug and we're
going to actually drill our bulkhead fitting in here. The reason why we're going to use
this surface is because in these cones, in these channels here, you can ball mill this
and get yourself a flat surface wherever you feel like putting your bulkhead fitting in.
But we're going to use this right here because it's already milled out. We're going to drill
right straight through here with a five eighth drill bit and we're going to Mount our bulkhead
fitting right there. It's going to give us good flat surface.
And when you're thinking about this where to put your bulkhead fitting, all you want
to think about is you want to think about your locking ring. It has to go back on here
and how your hose is going to be oriented when you have this done. So you want to take
your time here and make sure, "Hey, I'm not getting this in a restriction of... I can't
get my quick connect hooked up because of the electrical portion here on the canister
or it's going to hit in here or..." Just take your time and think and you won't have any
problems. So we're going to drill this out and mount our bulkhead fitting.
We've got our bulkhead fitting assembled here. You use Teflon tape on the quick connect and
to the bulkhead fitting. This old ring right here is your sealer that is going to keep
fuel from splashing out of the hole that you drilled. It goes right here on the bulkhead
fitting. Like I said, these kits have been changing here lately, so don't take this as
textbook, but as right of now this is current. So the five eighths hole. We've got here,
we've got a good flat surface. We made sure on the bottom side of it we've had a flat
surface. We actually hit it with a little bit of emery cloth to get everything in check
here.
So we're going to set our bulkhead fitting where we want it. Put our nut and our Teflon
lock washer or Teflon lock nut on the bottom and tighten it down.
Okay. We have installed our suction line. Now this is a... And again, I'm not going
to go over exactly what's in this kit because I feel like the kits are changing a lot. They
come up with a new update and a new idea. So you get a piece of corrugated fuel grade
hose that comes with this. There's also a piece of nylon rigid tube also and this small
mounting frame.
So what we did here was we mounted the frame to the canister exactly as the directions
called for and then the nylon tube entered the bottom of the canister, connected the
corrugated hose here to the nylon tube and they sent spring clips with this kit. We didn't
use those. We actually used a small radiator style clamp and tighten both of these up to
make sure that we didn't have any leaks.
Now this is installed, your nylon tube is against the bottom of the canister and one
of the first things that we want to do because we're almost done here, we're getting ready
to install the kit. We want to compress this the way it's going to be going into the tank.
Compress it and make sure that this isn't going to have any adverse effect on our tube.
Our tube is not going to fly up, go against an inch off the bottom of the canister or
anything like that. So this looks good.
We actually found a small peg down here that we pegged this against. You can see it there.
We're pegging this against that, and as you compress this, this stays perfectly still,
no problems with it flying out or anything like.
The last step on our install on this is we're going to drill one half inch hole, a couple
inches from the bottom. This will allow fuel to enter the basket. And if the basket were
to give, the pumper to overwhelm the basket, it'll aid in getting the fuel in here. So
that's our AirDog in-tank module upgrade. Quick connect, and if you need anything, just
let us know. We're getting questions. We'll be glad to go over it with you. Thank you.
