Walbro Motorsport GST400 400L/h high flow fuel pump for BMW série 3 E46

Here is our 400L/h high flow fuel pump from Walbro Motorsport . It is planned for BMW series 3 E46

As soon as an engine is optimized or prepared, it often happens that the original fuel pump is completely overwhelmed by events and therefore it no longer manages to deliver enough fuel. You should know that the consequences can be really very disastrous, with in the worst case an engine failure following too much excessive knocking (lean mixture, overheating).

If you install a fuel pump from Walbro Motorsport with a flow rate of 400 litres/hour, this will be a good way to make your mechanics more reliable.

Note that a high flow fuel pump alone does not increase the power of your vehicle. It will allow you to replace a tired or insufficient original pump in terms of flow, it can also meet an increased need in terms of fuel flow for applications subject to high turbo pressures, larger injectors, or any other changes.

This pump is compatible for: BMW series 3 E46

Compatible engine codes: M54B22, M54B25, M54B28, M54B30, S54B32
