Fuel System - Upgrade or not?

[prohydroracer]

Okay folks, I'm getting ready to pull my cab to do Head Gaskets, and Studs. I am still running the stock turbo and stock injectors and plan too for awhile. I don't use my truck for racing, but mostly for a daily driver and towing.

My question is, should I upgrade the fuel system while I have the cab off? And if you answer yes, which system and why?

I have done a lot of research on crossover lines, regulated returns, stage one kits, stage two kits, etc. I have been planning on doing an airdog as I like the way it removes the air from the fuel before it gets to the injectors. But due to all of the other parts I am buying, I can't afford to do a full blown regulated return and an airdog right now. And I understand that now is the time to do the fuel system as the rear of the heads will be in easy access.

I guess I'm just confused as to which way to go for now. If I was to add larger injectors in the future, they would be a small increase over stock for towing only.

I appreciate your response and help.

A regulated return or a lift pump such as an AirDog (no need for both) is more than enough for stock injectors and is sufficient for mildly bigger injector (155's to maybe 190's). If you are thinking of anything bigger (something larger than 190's), then you will need to go with a complete fuel system such as the AirDog2 to ensure you have adequate supply to keep the fuel pressure where it needs to be....

Nope, I wouldn't go bigger than 190's. I want to keep my tow-ability if that makes sense. But since I will have the cab off, I wanted to do either a crossover line, or regulated return if it would help me. Otherwise I will just do the Airdog when the time comes.
