One of the leading original equipment fuel pump suppliers, Walbro fuel pumps set the industry standard for quality and dependability. Walbro has entered into the performance world with the hottest selling and most frequently used performance pumps on the market.

There are actually quite a few different Walbro pumps that are manufactured. There are the 190lph, the 190lph-HP, the 255lph, and the 255lph-HP. To provide a greater number of fitments, the "flipped" versions are offered. The 190lph, the 255lph, and the 255lph-HP (no 190lph-HP) all have the inlet rotated 180 degrees from the inlet.

With these 7 pumps, Walbro can fit numerous vehicle applications. Each pump model is the same in terms of fuel flow characteristics.
