Irates full fuel system

[4.0l sahara]

what do you mean dead head?

The fuel is regulated before it enters the fuel rails in the heads. If any air enters the heads the only place for it to go is through the injectors. In a regulated return the fuel enters the back of the heads then out the front and into the regulator.

The fuel rail feeds from one side and does not have a return. If any air gets in.... it has to go through the injectors. This causes excess noise/damage to the injectors, and typically the injectors at the end (specifically #8) get a little starved for fuel.

I believe you are incorrect. The fuel is regulated after leaving the heads. Hence "regulated return"

You fuel line comes from the tank and feeds the rear of the heads and comes foward to the regulator and back to the tank. The regulator causes a "restriction" which causes pressure. Adjusted at your will.

How much of a pain is it to do put it on?

Honestly the hardest part of the entire thing will be the fittings on the front of the head. You need to pull the turbo and loosen the accessory bracket on drivers side to make all 4 fittings much easier. Once those are done the rest is a piece of cake. Just give yourself a full day to do it slowly and correctly!

Getting to the back fittings its a bear even with a t4 mounted turbo

How about the tank fittings? Need to pull bed or drop the tank? Worth doing so?

This system leaves the stock selector valve (on an OBS). On the SD competition kit you must remove bed or drop tank to install the 5/8 pick-up tube.

How do you decide wether it's necessary or worth it on a set up like mine?

Even a completely stock truck would benefit from it.

You would love the kit.

Clean looking, much better filtration, the pump is capable of more volume.

It is a upgrade on any unit. Your injectors will love you for it

No need to pull the turbo to get to the fitting, but it would be super easy if the turbo was already out.

Are the fuel Lab pumps dependable? How about SD pumps?
