ITP has been selling custom fuel system kits for the Ford 7.3L Powerstroke Diesel since 2002. Since then our kits have gone through several revisions in an effort to bring our customers the absolute BEST product that we could possibly offer. One thing that has never changed is our dedication to building the HIGHEST QUALITY fuel system product on the market. Our pursuit of constant improvement has resulted in a number of major improvements to our fuel system kits, the most significant of which are:

ITP Fuel System kits are built with the best quality parts available. ITP fuel system kits are assembled "in house" by ITP. Every part is inspected before assembly. Every assembly is put together by hand and re-inspected. Every kit is double checked for quality and completeness because it's our name on the label.

Our standard "In Tank" fuel modifications are 100% steel, we do NOT use any rubber hose inside the fuel tank. The pickup and return extensions are T-304 Stainless Steel tubing and the compression fittings are steel to ensure a solid "bite" into the tubing for a trouble-free, secure connection. We have NEVER used any brass compression fittings in the tank...and we NEVER will! Once you've installed our "in tank" components, we don't want you to have to go back into the tank again...unless you want to. Outside the tank we use high quality Gates "Diesel and Bio-Diesel Rated" fuel line and Stainless Steel clamps to eliminate the "quick disconnect" fittings and complete the installation.

Pre-Pump fuel filtration is very important in a modified fuel system. Whether you're installing the basic "in tank" fuel system mods or upgrading to a larger Pump & Pickup, you'll be eliminating the fine mesh screens installed in the tank by the factory. This leaves the fuel pump unprotected and can result in premature damage to the internal components of the pump as well as shortened service life of the stock filter. There is a very large selection of diesel fuel filter setups to choose from. Some offer improved water separation, lower micron level filtration and in the case of the AirDog...air removal. The prices of these filters are as diverse as the filter offerings themselves. We have chosen to use the Baldwin BF1212 spin-on filter and Baldwin filter head with our kits. This filter offers 99% filtration efficiency at 20 microns (significantly better than the stock in-tank screens) with extremely low pressure drop and better than 93% average water removel efficiency. The elements are inexpensive to replace and can be easily cross-referenced with elements from other manufacturers like Wix, etc. Of course, if you would prefer to supply your own filtration solution, we also offer our kit with no filter.

ITP Regulated Return Fuel System kits have always been built with high quality fuel pressure regulators. The Fuelab Fuel Pressure Regulator that we currently use is a solid performer with an excellent track record.

ITP High Performance Fuel Delivery Systems have a 5/8" T-304 S.S. fuel tank pickup, steel bulkhead hardware for the top of the tank, quality "Push-Lok" hose ends and enough Gates "Diesel and Bio-Diesel" rated -10 (5/8") fuel line to plumb up to a Crew Cab / Long Bed truck. They also include Gates "Diesel and Bio-Diesel" rated -6 (3/8") fuel line from the pump to the stock filter bowl or bowl delete, along with the necessary fittings to make the connections. The pump is mounted to a custom built ITP Mounting Bracket using rubber vibration/noise isolators and all necessary hardware to complete the installation is included.

It's fairly common to find low fuel pressure in stock 7.3L Powerstrokes. The factory spring/poppet style fuel pressure regulator isn't the most accurate device on the truck...to say the least. Several of our competitors are selling products that allow you to increase the fuel pressure to fix this problem (shim kits, stand-alone regulators, etc.), but these are really only "bandaid fixes" that don't address the major issues of the Powerstroke fuel system. Unlike fuel injected gas engines, the Powerstroke injectors don't use fuel pressure as a way to regulate the amount of fuel injected into the cylinder. Instead, fuel pressure remains constant and only needs to be high enough to guarantee that the injector fills properly and is ready to fire. If your truck requires high fuel pressure levels to run right, there is likely something else happening in the fuel/injection system that needs to be addressed.

Because of the poor flow characteristics of the stock "Dead Head" fuel system, a number of issues arise. Air can be trapped in the fuel rails, with the only path of escape being through the fuel injector. Injectors can be starved for fuel due to the lack of flow "through" the rail and the firing order of the engine. These situations can lead to one or more improperly filled injectors, which affects injection timing and causes noisy operation, reduction in power, reduction in economy and increases in smoke (unburned fuel).

The use of a Regulated Return type fuel system not only provides the ability to address the low fuel pressure issue, it also corrects the fuel flow through the heads and eliminates the fuel starvation and air trapping issues of the factory dead head system. With the correct fuel pressure and much improved fuel flow, every fuel injector has equal access to the fuel all the time. In reality, the "Flow" improvements made through the use of a Regulated Return system are much more important than the Pressure improvements from a simple shim kit or other fuel pressure only modification.

The factory fuel system includes a Check Valve (CV) at the inlet of each of the cylinder head fuel rails. These CVs are not designed to prevent reverse flow of fuel at shut down. In fact, they have an orifice bored through the middle of the CV that allows the pressure in the fuel rail to be relieved. It is our belief that the CVs were designed to prevent fuel rail harmonics from disturbing the feed fuel approaching the heads (possibly to prevent foaming or other air release?). We've done some "non-scientific" testing and found that the stock fuel feed lines (poorly bent steel pieces) actually caused a bigger decrease in fuel flow (more restriction) than the CVs did. Since most of our customers want to remove the CVs with an eye on total performance gain (reduction of any restrictions in the fuel system), our kits have been built to do just that. This poses no negative effects on stock or nearly stock trucks and offers the best possible flow for those seeking to go "wild".
