Ok so i installed a airdogII and it works great no problems but a friend of mine with a dodge has the airdog150 or whatever it is and he said that he installed a "draw straw" in the tank n drilled the tank n what not.. mine just tapped into the factory fitting and i didnt drill my tank..n i followed all instructions.

now hes telling me i did it wrong n that the fuel pump will have to work harder then normal..also i did happen to blow the inline fuse that runs to the battery for the pump about 3 weeks ago.no idea why tho.? When idle in park the fuel pressure is 64-68..when idle in D the pressure is 60-62. when driving the fuel pressure usually stays at 68 unless i let off the pedal it drops to around 60-64... i guess im asking if anyone else has there airdogII installed the same way into the fuel tank and what kinda fuel pressure they see at idle and cruise.?

Well as far as I know you installed it correctly because that's the same way I installed mine. My fuel pressure varies by + or -2psi. My average is about 64. You're well above the minimum pressure, which is 45psi. I wouldn't worry about it unless the pump is making weird noises or anything like that.

Have you changed your fuel pressure regulator spring to the blue one? The BB mod would give you similar results and save you $70. This helped keep my pressure a little more stable...I forgot to mention that before

Well you have to buy a kit from Ford that includes the spring. It costs $70. The other parts in the kit really aren't necessary to change out so that's why I just used a BB from a kid's gun. The spring weakens over time and this will help with idle quality and fuel pressure. Here is a link to another thread that thoroughly explains what you need to do. It's pretty easy and only took me about a 1/2hr. The thread says it's for a 7.3 but works for the 6.0 too.

Awesome,ill deff have to do this. ill just use a BB since it tells you in the write up which size it has to be.

At first i thought you were talkin about changing the spring inside the AirdogII lol

I know that someone else on here was having the same problem as you are and this didn't help him. I figured it's worth trying though because it worked for me and it's easy enough to do...good luck
