Walbro 350lph HP In-Tank Fuel Pump: 1g DSM

Genuine Walbro fuel pump.

This is one of the best kept secrets in the industry!  Walbro offers a whopping 350lph in-tank fuel pump with the same external dimensions as their famous 190 & 255lph pumps.  No need to go with one of the "big head" pumps and its issues with its universal install kit and awkward/customized fitment.  The 350lph HP (high pressure) pump uses the same install kit as their 190 & 255lph pumps and is just as easy to install.

We believe these pumps deliver the best bang for the buck. It is a well established fact within the DSM community that the stock fuel system is perfectly adequate for stock vehicles, but becomes increasingly inadequate as performance mods are added. In fact, even modestly modified DSMs are in danger of overburdening the stock system. This can lead to an extra-lean condition and, in turn, engine damage (up to and including complete engine failure!). It is for this reason that an upgraded fuel pump is considered one of the first essential modifications. The idea being that many subsequent modifications are only possible once the fuel pump (and the fuel system generally) have been upgraded to accomodate.

NOTE: Fuel pumps are rated by the amount of fuel they flow (under industry standard conditions) and are expressed in lph (litres per hour).

NOTE: This fuel pump is best suited to handle the demands of especially high horsepower, high fuel volume applications. As such, THIS PUMP WILL ALMOST CERTAINLY OVERRUN THE STOCK REGULATOR. Some means of controlling the fuel pressure at the rail is required. We recommend some kind of adjustable fuel pressure regulator (AFPR). We carry several.
