The three fuel delivery brands of Walbro, Marwal Systems and Pierburg are now part of the large, multinational TI Automotive organisation and all are becoming increasingly integrated for OEM and aftermarket applications.
Traditionally the US-based Walbro company has been concerned with pump and module production for US and Far-eastern vehicles whilst European based Marwal and Pierburg have served European OEM and aftermarket applications.
The combination of these three brands now offers European customers the most comprehensive coverage of replacement fuel injection pumps and modules up to and including this year's models.
