So if I am getting you right, I don't need to replace the fuel pump in the fuel tank and put in a Fass or Airdog and that should take care of any issues that i would have

 

If you bought the truck used then the OE pump may have been replaced with one in the tank.

If the pump is on the filter canister, it is an easy replacement with the same type pump. Can be gotten from Geno's Garage or some auto parts stores now carry a replacement. An after market pump such as the FASS or Air Dog is a better option but a little more costly and not as easy to install, although not hard.

If the pump is in the tank, I would first check that 12volts are getting to the pump just to make sure that the pump is bad. The tank will have to be dropped or the bed lifted and the old pump removed before installing a new pump or a draw straw installed in the tank.

 

The '03's did not have a pump in the tank, but it is mounted behind the fuel filter on the engine.
Some guys keep the OE filter and pump and install a Fass or Airdog and pump the fuel thru both. I chose to purchase the filter eliminator (a piece of machined pipe) and mounted the new pump next to the transfer case and ran a new line from this new pump directly to the injector pump.

If you don't have a fuel presser gauge, think about installing one now.

 

Yes they are lift pumps, the lift pump gets the fuel to the HIGH PRESSURE injection pump, I think you had the 2 crossed in your thinking.

 

Thanks for the help everyone. After looking online, I am kind of leaning towards the Raptor 150. What are the thoughts on that one? Pro's Con's. Or should I go FASS?

 

I went for the 100 because I did not need to drop the tank and install a draw straw. Unless you intend in the future to go to some exotic fuel system (read high power), why go for the higher fuel flows? For a stock over even a slightly modified system, the 100 is more than enough. Less work to install and cheaper.

 

If you use the 150 and don't install a draw straw in the tank, it will pull the fuel out of the basket in the tank, faster than it can get back in and you will drain the basket. Just get the 100 for now, much easier to deal with and no need to drop the tank. It is plenty of fuel up too a bit over 500 horse power.

 

ok I think after talking to a few shops around town and some buddys, I think i am going with the airdog system. Seems like it is best and would prevent any issues further down the road. And going to have a buddy and myself install. Any tips or tricks for the replacement?

 

Llift the bed to get to the tank. Will be less work if you do not have a 5th wheel hitch.

 

Yeah have a 5th wheel hitch. Also how long will the install take from start to finish.

 

Seriously,,, not that much work if you don't lift the bed. As long as your not doing a draw straw. Just reach up from the driver side of the tank and you can undo the fuel line. easy!

 

give yourself 2 to 3 hours the first time. So your not in a hurry

 

So which Airdog do I go with, the Airdog 100 or the Airdog 150, there is a 2 dollar difference in price.

 

that all depends on what mods you want to do. If it were me, get the 150 and not have to do any mods to fuel system later.

 

I had a 95 gph one on 450 hp and never had a hickup. No draw straw either.
So I guess its up to you now.
