AirDogII question

[sleeper1]

I installed an AirDogII this morning and set the pressure to 65psi. Everything seemed to be running fine but when I took it for a test drive, at WOT the pressure dropped to 60psi. From what I understand, it shouldn't be dropping this much. Can anyone chime in and let me know if this is normal or not. Thanks

hows your fuel filter in the valley of the engine

[sleeper1]

The fuel filter on top of the engine is fairly new. I have my fuel pressure gauge hooked right up to the fuel bowl so I'm thinking that if I'm losing fuel pressure there, then the AD2 isn't keeping up with the demand for some reason. I noticed there were two lines coming off the top of the fuel tank. If I hooked up the feed line to the wrong one, which I don't think I did, would this cause of loss in pressure?

Did you install the new pickup tube that came with the AD II?

[sleeper1]

I wasn't aware of any new pickup tube. I just looked over the directions and couldn't find anything either. I had to connect a suction line to one of the existing fittings on top of the fuel tank and then to the AD2 but that's it.

the AD2 doesn't come with a new pickup, it uses the factory pickup. A 5psi drop is more then acceptable especially at that PSI, factory spec is 50 +/- 5 PSI so you are still more then ok.

Okay good. I figured everything was fine by the way it was running and the fuel pressure was still way above minimum. I drove around a little bit today and I'm pretty happy with it. The truck definitely pulls harder at WOT on the highway and the engine does seem to run a little quieter...but that could be just me. Well thanks for the help guys

how hard is it to install the air dog 2? and where did you mount it

[sleeper1]

It wasn't very hard to install. You will need a fuel line disconnect tool, which you can get at an auto parts store and isn't expensive. It probably took me about 3.5 hours to put it in but I was taking my time. I ended up installing mine on the outer driver's side frame rail up tight to the bottom of the cab. I know people usually put it on the inside of the frame rail by the transfer case but I couldn't seem to fit it in and still have easy access. I think it will be fine on the outside though. It definitely makes changing the filters a lot easier

For what it's worth when I did mine I didn't want to have to deal with the fuel bowl filter anymore. If you take the stand pipe out of the fuel bowl you can do away with that filter too. It's about a 5 minute mod.
