The RaggDoll Motorsports Fluxion High-Flow Fuel Pump (HPFP) is a direct-fit fueling upgrade for the Porsche 718 Cayman and Boxster 2.0T and 2.5T platforms, engineered to eliminate factory fuel pump limitations. Designed for tuned street cars, upgraded turbo setups, and track-driven builds, the Fluxion HPFP delivers approximately 23% more fuel volume than the stock fuel pump while retaining OEM drivability, factory safety strategies, and long-term reliability.
If you’re searching for a Cayman Boxster fuel pump upgrade, high-flow HPFP, or a solution to fuel pressure limitations on the 718 platform, this is the pump built to support real power without compromising how the car drives.
Unlike 911 Turbo models that utilize dual high-pressure fuel pumps, the Porsche 718 Cayman and Boxster rely on a single HPFP. As boost, airflow, and ignition timing are increased, the factory fuel pump quickly becomes a bottleneck—resulting in fuel pressure drops, lean conditions, and restricted tuning headroom.
While the stock pump is adequate at factory power levels, it lacks the reserve capacity required for higher-output builds. The Fluxion HPFP solves this limitation with an OEM-style, plug-and-play fuel pump upgrade that increases fuel delivery without wiring changes, splicing, or external controllers—providing stable fueling and consistent performance as power demands rise.
Compatible with:
Not compatible with: Non-718 platforms
The Fluxion HPFP is ideal for:
Not intended for completely stock, untuned vehicles operating at factory power levels.
The Fluxion High-Flow Fuel Pump is fully plug-and-play and does not require calibration when operating within factory ECU logic. However, proper ECU tuning is strongly recommended when increasing boost, airflow, or running ethanol blends to optimize fueling, power delivery, and long-term reliability. Always consult your tuner prior to installation.
Optional/required extras: ECU tuning, ethanol calibration, supporting airflow or turbo upgrades
Designed, tested, and supported by RaggDoll Motorsports, the Fluxion HPFP delivers the fuel volume, consistency, and confidence serious Porsche 718 builds demand. We’re not here to sell flashy parts—we build components that solve real limitations and support real performance.

Built differently—because reliability matters just as much as horsepower.
Liza & most of the time Vince is amazing...lol. Nah, kidding, these guys are awesome folks to deal with. I purchased their Stage 2 turbo, turbo inlet, intercooler, engine tune, and high pressure fuel pump for my 2018 2.5L Boxster GTS and they're products and service have been top notch throughout the entire process.
Raggdoll Motorsports set up two dyno sessions for my Porsche Turbo S. The Porsche touts a 4.0-liter built engine and head work facilitated by Sam at ByDesign. Also has the XR ByDesign turbo kit with all the supporting mods. The first session the PDK kept transitioning out of manual mode. During the second session a boost leak at the throttle body boot ended the session early. We managed 812 hp on a Mustang dyno at only 20 psi of boost.
The people behind RaggDoll Motorsports have been in the game for a very long time and really know their stuff. They have a passion for modifying cars and are enthusiasts before anything else.
I purchased a RENNEN turbocharger for my 718 T. I had a special request, which was to get the turbine housing coated with Swain Tech white lightning thermal barrier coating and RaggDoll accommodated without hesitation even though it was something new for their team.
Hey All! Shout out to Liza and @Raggdolls718. Amazing customer service, product knowledge and a top quality product. Liza went out her way to accommodate my tight timeframe and the level communication and level of detail shared was amazing.
I purchased the Raggdoll Series One turbocharger upgrade and the turbo inlet upgrade from RMS for my Porsche 718 Cayman GTS and was very pleased with both the products and the customer service from RMS!
