Walbro high volume in-tank electric fuel pumps are the most reliable, powerful, and widely used fuel pumps on the market. Whether you just need to replace your stock fuel pump, or need additional fuel delivery capabilities for all the modifications you've done, a Walbro fuel pump will do the job for you. Customers with performance parts often forget about buying a new fuel pump, which is a critical part of keeping your engine running optimally. This is true especially if you have a turbocharger or supercharger kit, which usually only come with bigger fuel injectors, but not a bigger fuel pump.
There are three different basic pump models we offer in terms of performance: A 190 LPH, 255 LPH, and 255 LPH-HP. The letters LPH simply stand for Liters Per Hour, which is a measure of how much a fuel pump can "flow" (the higher the number the more fuel). The HP stands for High Pressure, and just means that the fuel pump is designed to operate efficiently at higher pressures, which are commonly needed on turbocharged/supercharged applications.
The Walbro 255 LPH-HP pump is a very strong pump and it can support up to about 600 horsepower. The 255 LPH is most commonly used for light to medium boost turbocharged/supercharged applications, and the 190 LPH is recommended as an excellent replacement for your stock fuel pump that is suited for use with all common bolt-on combinations (intake/header/exhaust/ECU/etc.).
Key Features:
- Rock-solid reliability.
- Superior in every way compared to your stock fuel pump (and less expensive!).
- Fits right in your stock fuel tank for best performance, durability, and ease of installation.
Important Application Notes: The Walbro fuel pump applications for most BMW 3 Series M3s include a direct-fit hardware kit that makes the installation easy. On newer BMW 3 Series M3 applications you may need to convert your fuel system to a "Return Type" system. On these applications, some custom work is required, and not all the parts in the installation kit may be used.
