So, we, Trusted Performance have created a Crossover Line kit to help equalize the fuel pressure between the two cylinders. This system is designed to balance out the heads. The 6.0 Power Stroke engines are designed to fire three cylinders on one side per revolution. So, there is great potential that the last injector in that firing order could see less fuel pressure and potentially starve.

 By connecting the two cylinder heads together, we reduce this chance of the injectors running low on fuel pressure and/or fuel. This system spares nothing.

 We manufacture stainless steel return lines that connect to the back of the cylinder heads and bring the fuel to the top of the intake manifold. We have given the design of these lines a lot of consideration. Being mechanics ourselves, we have cut a groove on the inside of the banjo fitting for an o-ring. This o-ring seals the banjo fitting to the head with very little chance of falling off during installation, unlike the normal banjo washers. If one does fall off, no worries, we include an extra o-ring just in case.

 Once the fuel has been directed to the top of the intake manifold, we use a steel braided Teflon lined hose to connect the two sides.

 The fuel line used is the standard for the automotive industry. It is made up of two different layers. The inner layer is extruded Teflon® and the outer layer is stainless steel braid. This is the ONLY line that is designed to handle diesel fuels, additives, Bio-diesel, Waste Vegetable Oils (WVO) and all additives known to us. (Teflon® is a registered trademark of DuPont Performance Elastomers.)

 This fuel line is designed to will outlast your engine and truck. The operating temperature of this line is -65 to +450 degrees Fahrenheit. That means your fuel system will still be working even when you stop no matter where you are.

 All hose ends are precision machined. These ends are designed to flow the maximum amount of fuel without sacrificing quality and risking cracking or breakage.

 All fittings in this kit feature either o-ring seals or washers. No Teflon tape is needed during installation. All fittings are adjustable allowing the fuel line to naturally run without binding or putting pressure on the fitting, which could cause failure.

 Do not be fooled by imitations. Many other companies use smaller lines and drill out the banjo bolt to increase flow. This helps, but it certainly is not a good alternative. We use the largest lines and fittings possible without having to use a reducer. In addition, our lines are specially designed for diesel fuels and additives.

 This kit does not sacrifice quality or reliability. We do not believe in that! This kit comes with a 50 year warranty against defects, leaks or anything else that comes up. The only exception is if the lines get cut, pinched and/or damaged by user error.
