Air Dog and Pre-Pump Filters
1 - 7 of 7 Posts
An Airdog can solve a lot of those fuel system issues that are otherwise dealt with in different places and more complicated ways, besides also providing better and easier-to-access filtration (which was the main reason I wanted it).
The only bad part is the cost (which may or may not be cheaper than doing all the other individual mods) and having to retrofit it to a van. In my case, I didn't have much room available, so it took a bit of engineering to make it fit, but I wanted it, so...
I got a kit for an F-series, though they also make them for Excursions I think.

Nunes,
How did you make it work?
And I just looked at a you tube video of an Air Dog running with just the key on, not started. It makes a loud sound, almost like a hydraulic lift, lifting up a car, type sound. Is yours noisy?
I want one for the same reasons, better filter of the fuel and the fuel with no air delivery. And how did you route the return line? Where does it dump the fuel?
I bought a set of the Ford 2000 Van Shop Manuel, the Dealer Issue set, Vol I & II, and it has the entire van broken-down in all the parts. Well worth getting a set. Like how to change a fuel filter, take the turbo out, the tranny etc. And even how the fuel lines go to the tanks, very helpful.
The DVD is nice, but you have to print so many pages. I got a nice, new set with no grease and missing pages. The Local Dealer gave me a deal.

It does make some noise when it runs, but you don't hear it when the engine is running. As far as the lines, I didn't do the final hook-up, just mounted the unit. It is meant to return the fuel to the filler tube, with a new fitting they supply.
I did read on the other thread about your wanting to run the return line to your rear tank. I wouldn't recommend that --- the Airdog runs a high volume of fuel. I think over time you would be pumping all the fuel from your main tank to the rear. And even if the Transfer Flow pump ran as fast (and I'm not sure it would), you would have a lot of fuel pumping thru your tanks. At worst, you'd eventually empty the your main tank, and overfill the rear.

The Trax II system with the Transferflow has the built-in computer that reads the gallons in both tanks, as the fuel is added or removed the System will turn on the rear tank pump and dump the fuel in the main tank.
If I dump the fuel in the main tank, the trax II will be telling the system to add fuel to the main tank. If the fuel is leaving the main tank, and the Aux Fuel is dumping in the main tank, then if I use the main tank for the return it may overload the main tank.
I'M going to have to talk to the tech's at transferflow about how fast the fuel pumps (GPH) from the Aux to the main.
You have 53 Gallons of fuel in your Van, that's incredible. My van holds 62 gallons and it's hard to believe when I look at a 55 Gallon drum my van holds a drum and a five gallon pail of fuel. 62x8#s=496#s .
I am doing more soundproofing in the undercarriage area of the van, I'M using Dynamat and 3M Rubberized Undercoating. The 3M stuff is great because it dries into a hard rubber that will not break-down if fuel or other things touch it. Many black, cheap undercoatings never cure and will smear and make a mess of it.

I'm not exactly clear on your concern, but I have the same rear TF tank and Trax system, with the Airdog installed its normal way.
Again, my point is that if you change design of the fuel flow out of the Airdog, you may get results you don't want. At best, you would be unnecessarily circulating all of your fuel thru both of your tanks via both pumps. At worst, you could effectively drain your main tank by sending it all to your rear tank via the Airdog (also unnecessarily IMO) a nd then not be able to pump it back out.
It's an interesting engineering question, but you need to compare the flow rates of the puimps from both the Airdog and the TF tank. If the Airdog outflows TF, forget it (and I would bet this is true). If not, then your concept may work, but I still don't think it's worth the additional complication or even necessary. Hooking up the Airdog to your main tank -- as it's designed -- will not change the level of fuel in that tank any more than normal consumption, as it's a constant circulation. And the TF pump will only come on occasionally to keep the tanks relatively equal.
Yes, I like the long range I get from the TF tank, I only wish I didn't need a shortened main tank for the Quigley conversion, or I'd have 62 gallons too...

hey, I would be very pleased with 52 Gallon range. I wish we could get 100 gallons of fuel under the van somehow, safe that is. The TF is DOT approved.
The 4" Magnaflow exhaust almost touch the 27 Gallon TF Tank, I have my entire Exhaust system wrapped with the Thermo-Tec 2" heat Header Tape Wrap, and it helps shield the heat from the exhaust heating the fuel in the 27 Gal. TF Tank. The Thermo-Tec Tape Wrap really cut's 1/2 the sound from the interior noise problem I once had. If your system is not wrapped you may want to consider it. I'M going to wrap the two pipes under the doghouse that are on the drivers side. They make a Turbo Boot and I will get one of those. That should really quiet the ride. I already installed a blanket inside my doghouse and it helped very much. Little by little the van gets better.
