Walbro 255lph In Tank Pump kit (BMW E30)

€ 95.00 EUR

Please read before purchase:


The E30 was fitted with two different fuel pumps during its production run, one made by Bosch, the other made by AC. While it is fully possible to make a Bosch version fit into an AC equipped car and vice versa, if possible it is recommended to take out your existing pump and identify which version you have in order to streamline the fitting process. It is seemingly not possible to determine which pump was fitted by year or model, so physical inspection is the best way to identify the model of pump.

The AC pump has a large 19mm opening for the filter.

The Bosch version has a smaller 11mm opening for the filter.
