Product Description

Introducing the new Fuel-It! 650HP line of fuel system upgrades!

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

As these cars get older and less expensive we're seeing more issues with the stock components and more demand for cost conscious fueling solutions.  Our new FI-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 FI-650HP components kick in to support the additional fueling needs of your high horsepower car.  With the FI-650HP line up 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 LPFP you can't supply the fuel needed to any of your other components.


What is the FI-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 FI-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 the EKP that runs your stock LPFP.


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. 

Add a Hobb's Switch?

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 a lock ring tool?

Removing the lock ring can be difficult and doing it with a screw driver often leads to a damaged/broken tophat.  For this reason we recommend using a lock ring tool to minimize possible damage.

Walbro 450 pump (F90000274)

Optional Wlabro 525 pump (F90000285)
