The Lethal Performance / DivisionX mustang fuel systems are the most widely used, best performing return style fuel systems on the market. These systems come complete with everything you need to convert your car to a return style fuel system. These systems are also completely upgradable so later down the road if you need to support more power or a different fuel type all that's needed is a pump upgrade and you're good to go.
This system comes standard with pre-assembled Fragola PTFE fuel hose. This hose has a PTFE inner liner, stainless steel braid and a protective black vinyl cover so the hose will not scratch any paint or parts of the vehicle or engine. PTFE fuel hose is more durable than the standard hose and prevents fuel smell typically found when using non PTFE lined hose.We have used the standard Fragola pushlite fuel hose on several of our shop cars with both gasoline and E85 with excellent results and no fuel smell. If you would like the non PTFE hose please choose that option from the dropdown menu. If you decide to purchase this kit with the standard hose Lethal Performance will not be liable for claims of fuel smell after installation.
The Lethal Performance return style fuel systems come in two different ways. For the 07-09 cars we use a traditional style setup where the regulator is placed after the fuel rails. For the 2010 model however we use a deadhead setup which places the fuel pressure regulator before the rails and dead heads the fuel rails. We have used the system in both configurations with excellent results even in the 1250rwhp range on E85.
The fuel lines in this system come pre-assembled. Due to this, the installation of the system becomes much easier as you will not need to install any hose ends. With that said, the system is designed to be installed one way. If you try and install the lines in any other configuration then the one we designed it for you won't be able to properly install the system.
Lethal Performance is not responsible for any additional hose or fittings required due to custom installation.
Easy to Upgrade- If at any point you grow out of the system you're in and need to step up to the next system to support more hp all you need is the pumps as all of the systems are the same except for the pumps.
The Lethal Performance / DivisionX Return Style Fuel System Includes:
DivisionX S197 Dual/Triple Pump Return Style Fuel Hat
DivisionX 3V High Flow Fuel Rails - Black Anodized
DivisionX 10 Micron Fuel Filter
PTFE Teflon Lined fuel hose (pre-assembled)
Aeromotive Pro-Series 4 Port 1:1 Boost Reference EFI Fuel Pressure Regulator
(2) Walbro F90000267 Fuel Pumps (upgradeable)
Lethal Performance Dual or Triple Relay Wiring Harness
DivisionX 0-100psi Fuel Pressure Regulator
XRP and Fragola Fuel Fittings
Fragola PTFE Pre-Assembled Fuel Hose Kit
Loom Clamps, Self Tapping Screws and Zip Ties
Vacuum Hose and T- Fitting for Boost Reference
Complete Installation Guide with Diagram can be downloaded from the Installation Instruction section at the bottom of our home page.
NOTES: 2005-2009 Mustang GT's and 2007-2009 GT500's to re-use their factory level sender. 2010+ GT's and GT500's use a different level sender than the 05-09 GT's and 07-09 GT500's. Due to that all 2010+ GT's and GT500's need to re-use their stock level sender with this hat and purchase the adapter to mate the level sender to the fuel hat.

NA King
I have used all of the big name tuners before I came across Ortiz and ran the fastest times I ever have, with Ortiz. . I ran my fastest time in much worse DA as well, compared to the other 2 big names. Don't waste your money like I did and go directly to the source of the fastest NA cars around!

Installed on 2018 Taurus SHO
Pump works great. To anyone who might want to save some cash and want a plug-in play install then order this fuel pump from 1A Auto
2018 Ford Explorer V6 3.5L Turbo Passenger Side Fuel Pump Module Assembly TRQ FPA72032. Its a simple replacement. Pumps are same size, no boring/sanding ridge to make pump fit. No splicing of wires either, connector from 1A Auto is plug and play. Just reuse spacer on pump and use one of the new o-rings and your done. Took me 30 minutes. I swapped out float with OEM, explorer and SHO floats are different. Only pain is retainer on rod on housing, its plastic and you will need needle nose plyers to get it off.

LOVE THE E85 KIT!
I bought the E85 conversion kit for my 3.7 from Ortiz Performance (OP) for a couple reasons. First, they specialize in the Cyclone whereas a lot of tuners don't want to bother tuning it (...cause what's the point?). Second, I talked via email at great length with one of their tuners, Lee Ament, and he was happy to take all the time I needed answering questions with detailed answers. Because of the amount of service I received before I purchased, I was convinced that I would be in good hands. I also liked that their favored injector (in the kit) is a genuine Ford part (OEM for the GT500).
I could tell right away that the OP gas tune was superior to the canned, Bama tunes I was using previously. I could immediately feel that shifts were taking 1/3 less time to complete and I could feel a lot of throttle boost across all rpm and especially in 1st gear (low rpm). I remember asking Bama to add more throttle boost to my tune and they simply don't make changes like that.
The E85 tune was great. Instant 10%-15% power boost and response across all rpm and really fills in the gap at lower rpm. Feels like I'm using a throttle booster, but I'm not.
There's only so much you can do to a Cyclone without forced-induction and E85 is a welcome, significant improvement if you already have everything else.
Installation is straight-forward, you can find a number of videos on YouTube that show exactly how to do this.
The one important thing to note: These injectors are taller than the stock injectors and
will not fit deep enough into the fuel rail UNLESS you do not use the stock fuel-injector clips!...which is completely OK! OP and all the above-mentioned videos will also state this. You will probably need a spacer (like a washer) on the 4 fuel rail bolts to fill a small gap. (If you don't pull the injector clips, the fuel rail will make contact with the manifold.) It will also run like crap until you put your first OP tune on it.
I recommend this product.

Wonderful Service
Sent my manifolds in (USPS wasn’t sure about the address but they got there just fine), took a handful of days to do the porting and about another week to ship back but I’m very happy with the results. Customer service was polite and helpful regardless of how often I messaged them, definitely would recommend

Roush air intake SHO
The over all ordering experience was a little lack luster at start. Ordered the intake on 12/3 and it was not going to ship for sometime due to a back order, which I don’t blame the Ortiz team at for one bit. However they quickly turn the ordering experience around, with rapid and prompt reply to my emails( no matter how much I bugged them). Once it was pretty clear the intake I wanted wasn’t going to ship before the end of the year they offered me another product at no additional charge. All in all I got a better product, excellent customer service and I’m glad and proud to say my 2015 SHO is tuned and take care of by Ortiz Performance. Greta company, great people and a great over all experience.
Thanks for all your hard work over the holidays and I’m glad I was referred to you by a fellow SHO owner.
Thanks Ortiz Performance.
Shout out to Lee as well! You rock man!

Great Look!
I wish the description would have more description as to what you are ordering and the difference with/without the rear silicone boot.
It is very difficult to install the rear silicone boot on the rear turbo. I would put slightly bigger clamps where they mount on the turbos as well. But the product is top grade! Looks really great!! Performs great as well. I will be doing the hot pipes for sure from ecopower parts as well.
I recommend this product.

@murdzilla3.7 Mustang
I purchased the Custom Tunes for my 2011 3.7, and i can honestly say Ortiz is the best tuner in the world in my opinion. 7 days a week Twice on Sunday. If you want to gap v8's and rip the streets slaying the competition, you have 100% come to the right place.

@murdzilla3.7 Mustang
I purchased the Ghost Cam and Bravo 240. Hands down the best decision in my opinion. The Ghost sounds so amazing, everyone is always complimenting the idle. The drive ability is great, no issues. The Bravo is also one of my favorite things as well. As I decelerate you can literally here the bald eagles and F18's, its wild!! Seriously though it sounds like thunder with a mix of gunshots in there.. its absolutely amazing in every way. Ortiz knows best!!

Power Pack
I have been running this tune/package on my SHO for over a year. Increased performance and fuel economy...never thought you could get both. Lee’s customer support and Luis’ tuning and turnaround time was beyond impressive. Luis reviewed multiple datalogs until deciding the car was running perfectly and safely, making smooth power and shifting on point. They answered any questions and concerns almost immediately and an updated tune was sent within 24 hours. That’s what will keep me coming back.
