Walbro Hellcat 525 fuel pump is a beast – the highest flowing offering from Walbro as a drop in pump (with larger base as pictured). This Hellcat 525 fuel pump is ok for use in Gasoline and E85. This fuel pump is a great option for cars looking to make over 500hp.
Compatible with Gasoline and E85 flex fuel ethanol blends.
Not a direct fit for many applications due to the large base on the pump. Please research installation prior to ordering. No returns on fuel pumps.
