Aircraft Equipment Problem Less Severe; Deviation / Discrepancy - Procedural Maintenance
General Maintenance Action
Aircraft; Human Factors; Incorrect / Not Installed / Unavailable Part
[We] were assigned to Aircraft X to troubleshoot a fuel leak out of #1 Engine. We noticed a fuel leak coming out of Fuel Pressure Relief Valve on the Main Fuel/ Oil Heat Exchanger. We created a non-routine on ELB [electronic log book] to troubleshoot and [someone else] transferred [the] ELB write-up to a paper write-up with work sheet.We removed the Servo Fuel Heater per AMM and removed the Main Fuel/Oil heat exchanger per AMM. We received a new Main Fuel/Oil Heat Exchanger but it was damaged when received; so we turned over to midnight shift.
B737 Maintenance Technician reported the replacement part was damaged.
