Original rebuild kit for AEM adjustable EFI fuel pressure regulators. The kit allows the regulator to be serviced and restores optimal performance without replacing the entire unit. It is an ideal solution for wear-related maintenance or as part of preventative maintenance on motorsport vehicles. The rebuild kit includes the essential wear components required to completely overhaul the regulator's internal components.
The kit includes a new diaphragm, O-ring and a large replaceable return orifice to ensure proper sealing and precise fuel pressure regulation. Replacing the diaphragm also upgrades the regulator to the latest valve design, ensuring correct operation and reliable fuel pressure control. The components are genuine AEM replacement parts designed to maintain regulator performance in EFI fuel systems using petrol, E85 and other compatible motorsport fuels.
AEM 25-392 fits several of AEM's billet adjustable fuel pressure regulators and is suitable for maintenance, repair and refurbishment of existing regulators. The kit is supplied complete, making servicing simple without replacing the regulator housing.
