Also Wondering if the airdogggg fuel system is worth my time and money ??

 

YES!! I would use either the AD100 or AD150. It will quiet down the injectors, remove all the entrapped air and filters the fuel better than the OEM filters. It's worth it!

 

Get the AD2 though, since it is regulated. Then you wont have a need to spend $700 on the ITP regulated return setup, since it is built into the AD2.

An AD2 is a worthwhile investment for even a stock truck, it will save the life of your injectors. A stock truck with just a tune can drop fuel pressure, so having the AD will take care of that. I believe all of the AD2's are the 165 versions now.

 

Thanks Guys

 

The OEM regulator works just fine, install a fuel gauge and see what's really happening. I have read of too many issues with plumbing the return when using the AD2.

Add to your install the newer OEM Fuel Regulator spring to maintain greater pressure. Buddy just did the OEM kit alone and is running a steady 60-65 PSI during all modes.

 

Where did you read about problems with the return line? I've seen a couple install threads pop up recently with pics and don't recall reading about issues with the return line? I would do it just to get rid of the stock pump. The AD is just a pusher pump is it not? The AD2 is the whole setup...

 

so were do i get this spring at and do i have to remove my filter housing to install it cuz im sure that is a hell of alot cheaper than the AD2??

 

There were several early installs without the modded tubing "Y" that were spitting fuel out of the OEM return line that is disconnected at the tank.

The OEM pump will do the job just well as the AD2. It can push out fuel over the suggested 75PSI max. If there's no issue with the current pump WHY replace it?

Yes the AD is a pusher and if need be can be added with a Raptor in line while removing the OEM pump.

It's all the same just what do you really want in the end.

There are a few aftermarket springs out there currently. Ford has recently repackaged their Regulator kits to include the new spring. Locate pn# 3C3Z-9T517-AG at your dealer. It's the complete regulator kit so it's not just the spring or cheap. ($65) I'm just going to rebuild my whole fuel regulator so the kit it's not a waste of money.

Install a fuel pressure gauge first to know what the drop is in your system. If you need the AD or the regulator then take your pic. $65 for a spring is cheaper than the AD but the AD ADDS so much more life to the injectors it's worth the upgrade as well.

 

I can't say I agree with this. The stock pump can push the 55psi needed, but even with a tuner you can drop the pressure on a stock pump. If it doesn't, then great, but chances are it will. Even with the new spring to hold more pressure, it doesn't mean the pump can keep up with that. The spring isn't going to replace the airdog in anyway. If the stock pump cant keep up with 55psi with a tune, it's not going to keep up with the spring either. The spring is only a "fix" for a problem that already exists, which is a worn out spring. Having a worn out spring will cause problems yes, but like you said why replace it if it's not necessary? If the stock one can hold 55psi, you dont need to get another one.

The best way to see what is going on is a fuel pressure gauge, you are right. That will tell you exactly what you need to do.

I've heard of no issues with the AD2, and it makes sense to purchase that IF you need a replacement pump as it is regulated.

 

I got my spring from Gillette Diesel. It went into the bottom of the housing, pretty straight forward install. It's a little longer and stiffer than the OEM. For 20 bucks, I'm thinkin it's pretty cool.

My truck was having NO issues and I believe it helped the dead stop acceleration when at operating temp 180 ~ 190.
