Lethal Performance 07-09 GT500 Level I Fuel Upgrade Kit

Level I Fuel Upgrade Kit Includes:
-Fore Precision Works S197 Billet Fuel Hat
-Hat to Stock Fuel Line Adapter
-Ford GT Supercar Fuel Pumps (2)
-Fuel Level Sending Unit
-Detailed Installation Instructions

Introducing the Lethal Performance Level I Fuel Upgrade kit for your S197 Mustang. The Level I upgrade kit is the first step in eliminating the restrictions of your stock fuel pump assembly. The GT500 fuel assembly uses 2 pumps ran by individual fuel pump driver modules. This is definitely one of the most efficient ways of setting up a returnless style fuel system and is very similar to the fuel system used on the Ford GT40 Supercar.

Although the stock system is efficient and performs well we've found several things which can be improved upon. For one, the stock assembly runs both fuel pumps into a Y and out the single outlet of the stock assembly. We also know that the stock GT500 assembly uses 2 check valves. Although the check valves play a role in assisting from a cold start for they keep fuel pressure in the lines while the car is off but we we do see them to be a restriction for higher HP cars. Most of the time the side effect of these check valves is a hesitation between shifts in the upper RPM range. Just like the disruption of flow on your intake system lowers it's efficiency the check valve acts in a similar fashion in delivering fuel. One of the check valves is located inline with one of the fuel pumps just before the in-tank Y-block and the other is found on the actual fuel bar which is the white bar that sits on the pumps. The second check valve is built into the bar itself and requires a certain level of fuel pressure for it to open. Even when the level of pressure is applied it's still quite restrictive as the size of the feed is much smaller than the feed that flows fuel from the other pump.

This is where the Level I fuel kit upgrade plays it's role. The level I fuel kit uses the Fore Precision S197 Billet Fuel hat and a special billet adapter plate which allows you to still use the factory fuel lines. The main purpose of the Level I kit is the remove the in-tank restriction of the stock tank but not requiring you to upgrade anything external. This means that all stock lines and rails can be kept in place and used with no modification. By upgrading to the FPW S197 hat the flow of fuel is increased as the in-tank check valves no longer play a role.

The Fore Precision Fuel Hat is a direct replacement for your stock fuel assembly. Still utilizing the stock level sender placement. It reads fuel levels just like the stock fuel system did before. No cutting, drilling or modifying is necessary to fit the FPW hat into the tank. The Fore Precision hat fits right in and is securely fastened in the same fashion that the stock assembly does using the same stock gasket and safety ring.

The Level 1 Fuel Upgrade also utilizes a pair of the high performance Ford GT Supercar pumps. They simply slide into place on the Fore assembly and provide the fuel needed to support some hefty power levels and not needing the assistance of an external voltage booster to do so. The best part about this system is that it can be easily upgraded to the next level. So if you've got a ported blower, running a lower and upper pulley or plan on upgrading to an aftermarket blower you can purchase the components needed to upgrade the system. There's several ways to upgrade so you as the customer have the choice to do what you feel is needed for your specific goals. Whether it be adding another pump or stepping up to aftermarket lines, filter or rails upgrading the system couldn't be easier.

Jared,

What kind of horsepower will it support?

Thanks

Yep wondering the same, dual GT500 fuel pumps support up to 1000 horsepower, this is a single Ford GT pump which costs about 50% as much as what I've heard a dual GT500 setup costs.

Interesting...... I may upgrade!

Dave,

Good question. Well there definitely needs to be more testing to help answer that. In regards to the stock GT500 fuel system with no BAP, still using the 48lb injectors on our GT500 we made 726rwhp and saw low 90% duty cycles.

With this new system it uses different pumps but also has removed the 2 check valves which the stock GT500 fuel system has. So I'm going to take a pretty educated guess that since the GT pumps perform very well and we're still using 2 of them like the GT500 system does I would believe that we could atleast support the same amount of power that we did which is that low 700rwhp range. How much more than that we see with the Fore setup, being that we removed the 2 check valves but are still using the stock lines is the magic question. I'm working with Justin at Fore Precision in flow testing both the stock GT500 hat assembly and the Fore Hat asembly with 2 pumps to see how much of an improvement we see in flow from the removal of the check valves.

I do feel that those are restrictictions which the data will hopefully support. In addition to that both Justin and I feel that at the 700rwhp+ level not only are the stock check valves of the GT500 fuel system a restriction but also the fuel lines themself. By upgrading to a larger fuel line you should be able to support more power as well as take some of the load off of the pumps which will lower duty cycles.

We've got a lot of great data which we'll soon release about the BAP and it's effectiveness. There's quite a bit of info that people will be surprised to know which we feel will help them understand their fuel systems better and make the right choices when deciding to upgrade them. Until then it's 6pm and I'm outa here!

Hah Send me one ill test it!! here is my hackup job This is an old picture all the tubes are shorter and the pprv was deleted. I get 49% Duty cycle at WOT- 21 % at cruise or idle.

Twin GT pumps. Did I miss the price on that setup in this thread? So the Stock FPDM is good to run this setup? Do you have more pictures? I can't see where the crossover tube connects. I've ripped about 9 of the rubber duckbills on this setup. I found a distributor for them same ones that ford uses.

LOL... FrankenPUmps!! LMAO.. Sorry bro but I had to. The funny thing is that we used to modify hats in a similar way so I can relate to you and know how much of a pain in the *** those systems are to build. Thats what prompted me to work with Fore Precision to get this S197 hat to be a reality.

As far as the price goes the hat itself is $420.00. The level sender you have on your hat will work on the Fore one so all you need then is the hat to stock line adapter ($45) or an aftermarket line setup. In regards to the FPDM. For a long time we sold our original fuel upgrade kits with dual gt pumps and the single stock FPDM. We never had a problem nor have seen any failures on an 05+ car from doing so. It's known that the GT pumps draw more amps than your stock pumps do, and that the stock non-modified FPDM isn't made to handle that draw. However, again we've seen no failures. Our approach with this system though is to make the most efficient system ever for the S197. That means no second guessing whether the FPDM will handle the power or not. We built this system with 1000+rwhp capabilty. So we highly suggest if you want to get the most out of it, handle the power and keep duty cycles in check to run the dual pump system with the dual GT500 driver harness and FPDM's. For the triple pump system we also highly suggest the MDM module which is built around delivering the pumps what they need as well as letting them take what they need to run efficiently.

So I'll close with this. You can choose to go with 2 pumps on 1 module if you like. There's no proof of failure on the 05+ cars so it does indeed work as all of our past systems were run with success in the same fashion. However, the most efficient way to run this system is with the MDM or GT500 dual FPDM harness.
