If your power goal for your S65 E9X M3 is 650whp or less and you need to upgrade your fuel system, you've come to the right place!

As these cars get older we're seeing more issues with the stock components and more demand for cost conscious fueling solutions. The new Fuel-It 650HP line of fuel system upgrades are designed with those needs in mind while maintaining a budget. They make the most of the stock components to maintain stock reliability and drive-ability but when the boost gets cranked up, the Fuel-it 650HP components kick in to support the additional fueling needs of your high horsepower car. With the Fuel-It 650HP lineup, you can upgrade your components all at one time or upgrade them as time and budget allows.  If upgrading one component at a time, we'd recommend starting with the LPFP first as that is the heart of your fuel system, without a good Low Pressure Fuel pump (LPFP) you can't supply the fuel needed to any of your other components.

What is the Fuel-It S65 650HP LPFP Upgrade?
No iDrive warnings, no EKP issues, and no sending your fuel pumps in for repair or upgrade. This new line of Low Pressure Fuel Pump (LPFP) upgrades utilizes the stock pump assembly to meet everyday driving needs but when the boost kicks in, the Fuel-it 650HP secondary pump kicks on to support those high boost fueling needs. This system requires no modifications to your stock system, including the bucket, wiring, or stock plumbing so that it is reliable and easily reversible. There is no tearing down your bucket or sending it in to be upgraded.  Install only requires adding the additional pump assembly to your fuel tank where it sits side by side with your stock pump assembly and then installing the additional wiring harness.  The secondary pump then runs in parallel with the stock pump making use of the stock capacity while adding up to 200% more capacity to your existing system.  Doing it this way eliminates any additional strain on your stock wiring and the EKP that runs your stock LPFP.

S65 LPFP Upgrade Options:
These kits are only available as an add-on assembly and you will retain your stock pump. The secondary pump requires the additional wiring harness and will require that you add two 9/64" power terminals to your tophat. 

Upgrade to a Walbro 525 fuel pump? (Add $75.00)
Our kit comes standard with the  Walbro 450 pump but for those looking for even more flow, we offer the Walbro 525 upgrade. Select it if you want the most out of your new fuel pump. 

Add a Hobb's Switch? (Add $45.00)
Your secondary pump can NOT run full time, it must only be run under boost only.  Running it full time will place additional strain on the stock system, will lead to high fuel temps, and pump or component failure.  To turn the secondary pump on under boost we recommend running a 4psi Hobb's switch.

Add an optional lock ring removal/Install tool? (Add $40.00)
Removing the lock ring can be difficult and doing it with a screwdriver often leads to a damaged/broken tophat.  For this reason, we recommend using a lock ring tool to minimize possible damage.

Included with all S65 LPFP upgrades:
• Walbro 450 pump (F90000274)
• Optional Walbro 525 pump (F90000285)
• Black Anodized Custom fitting
• Pump brackets
• 9/64" terminals and associated hardware
• Fuel line
• Replacement PITA clip
• Wiring harness
