## 🔧 Product Description

Brand-new genuine Volvo Penta/Bosch high-pressure fuel pump for TAD5 and TAD7 common-rail engines. The engine-driven pump raises filtered diesel to the rail pressure commanded by the ECU and supplies the injectors through the high-pressure circuit.

-   Volvo Penta TAD550GE
-   Volvo Penta TAD551GE
-   Volvo Penta TAD750GE
-   Volvo Penta TAD751GE

## ⚙️ Key Features

-   Matched drive interface and pumping-element capacity
-   Used with leak-off line 21156370 and hollow screw 21141582
-   Requires exceptionally clean fuel and correct feed pressure
-   Pump installation must follow timing, priming and cleanliness procedures
-   Engine type: Volvo Penta 5- and 7-litre common-rail industrial diesel

## 🔌 Function

Compresses diesel fuel to the pressure required by the common rail so the ECU-controlled injectors can meter fuel accurately.

## ⚠️ Common Signs of Failure

-   Long cranking or no-start with low rail pressure
-   Loss of power or derate
-   Metal contamination in the fuel system
-   Fuel leakage from the pump
-   Rail-pressure control or pump-performance diagnostic codes

## 🛠️ Service Notes

-   Treat cleanliness as the whole job: work in a clean area, cap every open line and port as it is opened, and let nothing enter the system on a cloth, a finger or a tool
-   Find out why the old pump failed before fitting a new one — a pump that has worn internally sends metal through the system, and a new pump fitted into contaminated fuel and lines will fail again quickly
-   Renew the fuel filters and check the low-pressure supply, tank and lines are clean and delivering properly; where contamination is found, the lines and soft hoses must be cleaned or replaced, not simply flushed through
-   Fit the pump with new seals and the drive engaged, timed and tightened as the workshop manual for your engine specifies, and do not open or attempt to adjust the pump internally
-   Prime and bleed the system by the manual procedure, then check for leaks — never slacken a fitting or search for a leak by hand on a running high-pressure system, as the fuel jet can penetrate skin
