Let’s face it. You procrastinate filling up the truck at the end of the week or end of the day because it is getting more and more expensive. If you remember back to a few years ago, you could fill your truck up for $50 or $60. Now, at least for me, you’re looking at $100+. Speaking of fuel, not only is it expensive, but the components that pump and fire it are, too.
Newer 6.7-liter Power Stroke engines are equipped with a CP4 high-pressure fuel pump. If you haven’t heard, these pumps can be problematic. In fact, they’ve been known to take out entire fuel systems because of disastrous failures. Our friends over at SPE Motorsports saw the issue and have appropriately addressed it to keep our newer Super Duty’s on the road.

When you’re working with a truck that sits higher than normal, you can never have enough steps or ladders.
The CP4 is very susceptible to contamination due to its tighter internal tolerances and high operating pressures. When the pump fails, it sends its remains into the rest of the system and requires several thousand dollars in repairs. So, the SPE 6.7 Power Stroke Disaster Prevention Kit + Exofilter was born.
This kit is pretty self-explanatory. It does what it implies. It prevents the CP4 pump failure from destroying anything else. Per SPE, “This may seem like a simple concept, but other systems on the market are incomplete in our eyes. We have rewritten the book and designed a kit that has none of the installation downfalls for shortcomings.”
What Does It Do?
The SPE disaster kit bolts to the front of your CP4 high-pressure pump and changes the routing of the fuel flow so that the lubricating fuel is divided, feeding the fuel to the MPROP from the fuel filter and not from the crankcase of the pump. What this does is prevents contaminated fuel, if there were a failure, from getting into the high-pressure fuel system.
Other kits to combat this issue fall short of this, says SPE. “This is where every disaster prevention kit on the market is missing the mark. They send the contaminated fuel back to the tank, contaminating the return side of the system. This trashes the lines, fuel cooler, and tank. The ExoFilter allows the customer to monitor the system when maintaining their vehicle so there isn’t a surprise failure.”
Because you have access to this filter, you can monitor your fuel system, and when the filter is clogged, you’ll know it. The truck will have symptoms of an issue and you can shut the truck off rather than sending debris-filled fuel into the tank and passing it through the fuel filter, lift pump and engine. With this sweet feature, you can open up the filter, check for debris, and either go on your way or wash out the 20-micron, metal filter the fuel passes through.

Diesel engines are large and expensive. It is crucial for you guys to continue to instill them with the best parts available. Keeping them going and maintaining a healthy operation is important.
Our unmolested 2015 Super Duty is in dire need of some insurance protection. With several thousands of miles on the Super Duty’s odometer without issue, we better play this safe. SPE hooked us up with a disaster prevention kit and ExoFilter to show you guys how to put it on and educate you about how critical it is if you’re the owner of this model truck.
Benefits

- Black anodized 6061 billet aluminum hard parts
- Industry-first patented return side 20-micron fuel filter (reusable)
- Allows health monitoring of the CP4 pump
- Reversible (kit can be removed)
The installation of this kit begins with the removal of everything in the way. As you can see in the photos above, our technician removed the intake manifold lid which exposed more of the parts we need to reach for this to go on. Once the pump is exposed, we then prepared our new plumbing, fittings, and new filter for installation.
Each fitting and line went in their respective spots and SPE has developed this kit in a way that makes for a smooth, clean install.
Let’s Go Further, Shall We?
With the SPE Motorsport disaster kit in place, we’re done, right? Well, the high-pressure injection pump is now safe, but we want to keep the upgrades coming from the standpoint of fuel. As mentioned earlier, fuel is expensive. We want to go as far as possible without having to stop anymore. This is where our friends over at Titan Fuel Tanks come in.
This Super Duty, now that the fuel system is safe, needs something that can allow it to keep going. How are we going to do that? How about an oversize 65-gallon fuel tank. Titan’s oversize tanks are heavy-duty units that are almost identical to the factory units. This tank, specifically, is for Ford diesel pickups with an 8-foot bed and is constructed of military-grade, cross-linked polyethylene.
Included are the powdercoated or plated steel mounting straps, extruded rubber mounting bushings, and accessories. The tank features a low fuel trap design and hangs approximately 1-inch below the bottom of a stock tank shield bracket. The overall depth is 2.5-inches more than a factory one. What Titan has done is it has found every open available space under these trucks and made a tank that fits within that area.
Per Titan, its tanks provide you the freedom to chase your dreams. With double the capacity over a stock, this Super Duty can go twice as far. Backed by a lifetime warranty, and durable construction, this truck just keeps getting better and better.
Down And Out, Up And In
The installation of one of these oversize Titan tanks is pretty self-explanatory. You’re replacing the original tank with this one. Since it is an OE-style replacement tank, there are no fitment issues. Because it utilizes the factory fuel sending unit, this is a seamless job with no modifications needed. Double the capacity and double the distance while still maintaining a working fuel gauge.
To begin, the truck was put up on a lift where it could be secured. With the truck safely in the air, the factory fuel lines were loosened and removed from the tank. With nothing else keeping the tank connected to the truck, the straps were then removed, freeing the tank completely. We then brought it to the ground where it sat next to the new oversize one and you can clearly see the difference.
Obviously, it was much larger and much cleaner, but you can tell this new tank is built like a fortress. Next on the agenda was relocating the factory fuel sending unit into the new tank. With some basic tools, the lock ring that holds it into place is carefully removed and taken off. Once this was out, we sat it into its final resting place.
Configuring the pump and line connections to match the factory one, so the lines will reach still once the new tank is installed, is next. With the pump in place, up we go. Using a tall jack, the new tank is lifted into the air where it slips into place. The fuel line and electrical connections are made, and all that remains is installing the new tank straps. Tighten up the hardware and you’re ready to rock and roll.
Could you stop here? Sure. Titan offers a few other options if we want even more capacity. This includes its 15-gallon Sidekick tank, which is perfect for transporting any liquid you want in the bed of your truck. This is handy storage for nonflammables or combustibles or even Diesel Exhaust Fluid. Like its larger counterparts, the Sidekicks can help, too!
The big boy tank we used from Titan is backed by a lifetime warranty and they guarantee the durability and trust it will last us for any trip we’re on. We are extremely satisfied with how this project turned out. We’ve taken a truck with problems and addressed them with the best possible options, we’ve doubled our travelable distance with our oversize tank, and we can’t be happier.
