I put the 150 on mine the install went great. I will agree on the hose and fittings that sucked. I am still having hard start issues but I had them before I put the airdog on so I am still looking for the problem. I have a ? for you airdog 150 guys. Whenever I hit some washbords on a gravel road I can here the pump hit the bottom of my cab. any body else have this problem and what can I do to fix this. I am sure it is not good for it. thanks mike

loosen the frame bracket bolts and readjust them to give you more clearance. loosen the top and tighten the bottom, that will pull the pump down

the air dog 100 is easier to install becuase you dont have to drop and drill the tank I think every thing else is simple but if you go with the 150 make sure the tube is toward the the middle of the tank. The hose was a b_____h to get on the fittings but over all when the bugs get worked out it will be fine the other thing i might add is if you think about the unit that drops in the tank and modify the lid or use the existing opening that are there then youll be alright. when the truck is running you can not hear the pump running the newer 3rd gen trucks are quieter than my truck and may be able hear it. oh well all this rambling is making my fingers tired so i hope this helps you a little.

I installed mine in the sender assy, so that the straw whent into the basket, BEFORE you drill the hole check the back side of the sender as there are ribs there that can and will interfer with the grommet. I had to pull the bottom off the basket to remove the orginal pick up and I cut out some of the orginal plastic line as it was in the way of the straw, it kind of forced it to one side. as per Mark from Coaltrain I also drilled a couple(4) extra 1/2 holes in the lower basket just incase the Airdog could draw more fuel than could get in the basket. I left the lower screen in place. getting the proper straw measurement was the tricky part. I have no such low fuel issues.

other thing that I noticed was that the fuel return (hot fuel from engine) is dumped straight into the basket, but it does not seem like a very good idea to me, If I had, had the time I think I would have re-routed it

even with your draw straw at the back of the tank I wonder if there is anyway to leave it there and put a "basket" under the straw?? Maybe remove the bottom 1/2 from a sender assy and set the draw straw into it?? just throwing out ideas.

Thanks, Nick (nickg). You don't happen to have any pics of how you did that install, do you? If so, I'd really appreciate it if you'd share them...

Thanks!

Well, my lift pump was only putting out 2 psi at WOT so after lots of research I decided on an Airdog 150 setup. I now have it installed and operational and thought I'd share my thoughts on this product.

PROs:
1. Fuel pressure is in the 22-23 psi range at idle and 21+ at WOT. Great!

2. I can't hear it in the cab at all if the doors are closed. Nice...

Sadly, the list of "con's" is quite a bit longer. The last two (in red) are the ones that concern me most.

CONs
1. Putting the 3 barbed elbow fittings onto the blue hose simply sucked. Even with some motor oil in the hose and on the barbs it was an absolute bear getting them seated. I ended up needing more fuel line (I mis-measured on the second hose and made it too long) and used some 1/2" hose from NAPA and it worked as I would've expected. The fittings slid in nicely and wouldn't pull out. Not sure why the Airdog hose didn't work that well.

I had no problems with the fuel lines or seating brass fitting. I had got all mine done in a single day. The trick is to start the fitting in the hose slightly... Then put the fitting against the ground or a work-bench and push! Easy as pie!

2. The instructions weren't bad, though I think they could've been written a little more clearly with little effort.

True... The instruction should be written solely for the model your got and not for 2 different models...

3. The draw straw was supposed to be trimmed so that it was only 1/4" from the bottom of the tank. Most people have to trim them. Mine was too short and sits probably 3/4"+ from the bottom.

I got mine with in about 1/8" inch and added grooves in the end of the straw to keep it from sucking the bottom of the tank.

4. I primed the system, but it still took some effort/time to get it started. I had to work the throttle to get it to start.

Had zero problems getting primed up. I used the Dodge FSM method and fired up the first time...

5. I pulled out of my driveway with just a hair more than 1/8th of a tank. It died in the street (no fuel pressure). I added another gallon of fuel and managed to barely coast my way into a gas station about a 1/2 mile away. I suspect this is also due to the draw straw simply being too short.

6. Now warm starts often require me to work the throttle to get it fired up.

In my research I didn't read anything about people having these issues, other than some folks have hot start-up issues sometimes. This is a quality product, but has anyone else run into this? I was quite surprised and I'm now concerned how about how "small" my tank is now.

Thanks,
Tommy

Most of the problem is you draw straw was cut wrong...

I can pump nearly ever onuce out of my tank... :thumbsup

Here is my write up on how I did mine...

You think rectangluer vs. V notches would make that much difference? I think since this it the third time I'm dealing with this mess I'm going to take my time and find a way to fit this straw into the OEM baffle.

Also, I wonder if it's easier for you long bed guys to mount the straw farther forward? Most of my tank sits directly under and very close to the bottom of the cab.

See what I'm talking about?

Here is my setup and it took only a hour to install...:w:

I pulled my tank out from under the truck and was simple as well. Two bands on the tank, two hoses, sender, and carrier bearing (dropped the driveshaft) and the tank came out...

As for the tip of the straw I notched it with my grinder. Just lightly touched the end of the tube...

TommyR, in the pictures it looks like the return from the airdog to the fuel filler neck is pinched. I have mine rotated 180* , it faces the cab. I also have the 150 but if I did it again would probably gone with the 100. Good luck.

Yeah, I've seen your setup several times. I know you didn't have to run lines, but you must work really fast to do all that work in an hour!! Although I wouldn't doubt having a long bed may have made things easier. It's cramped under mine.

So you notched a rectangular section as opposed to my V-nothces?

Thanks for noticing that, but I strain-relief it when it's installed so there's no kink in the line.

I agree. If I could do all this again, I'd go with a 100. I should also point out that while I'm happy that Pure Flow sent me a few extra springs to reduce the pressure of my pump (22-23 psi!) I'm rather upset that I even have to do this in the first place. Apparently, the quality control on their springs isn't up to snuff.

Well I kind of cheated... :lol3: Stock pump and vulcan big line...

The new setup... If you look close you can see the previous mounting holes... Notice the fuel line is dirty... Yeah I re-used a lot of hose...

I already had a Vulcan Big Line Kit in the truck so mounting the pump what 4 allen screws and 3 bolts... Run the wire the same place the old Vulcan lead was. Then install the return line... I pull 2 clamp and cut the hose and installed the fitting... I used my old wiring as a snake to a pull the new through using the old. spent a hour doing this...

But skipped the draw straw because I had a trip to make up north and figure if the stock sender would hold up then I wouldn't bother... But the stock sender kept pulling the fuel pressure down...

So next avalable time I installed the draw straw. I can sit under the truck and grab the sender ring and loosen it. Left it attach to the lines and electrical. Pull both band (2 nuts) carrier bearing (2 bolt), slid the tank out on the floor (empty of course). Drill 1 hole and trimmed the tube. Notch the end and re-assembeld in about a hour...

I used all air tools so wrench time is reduced...:w:

So roughly 2 hour total but the draw straw was really easy to do...

But if you where to start from ground up yeah... It would be a long project...
