## 🔧 Product Description

## ⚙️ Key Features

-   Cross-drilled fuel banjo screw
-   Original thread, length and internal passage diameter

-   One hollow screw supplied
-   Engine type: Volvo Penta 5- and 7-litre common-rail industrial diesel

## 🔌 Function

Clamps the banjo fitting and provides an internal passage for fuel supply or return flow.

## ⚠️ Common Signs of Failure

-   Diesel leakage at the sealing washers
-   Restricted fuel flow from contamination
-   Cracked banjo fitting from over-tightening

## 🛠️ Service Notes

-   Check the through-passage is clear and clean before fitting; a blocked hollow screw starves whatever it feeds
-   Always fit new sealing washers, one each side of the union where the original had them, and never reuse a crushed washer
-   Hold the fitting or pipe end against turning as you tighten, so the line is not twisted and the union is not pulled out of position
-   Tighten to the figure in the workshop manual for your engine — these seal by crushing the washer, not by force, and over-tightening splits the head or shears the shank
-   Bring the system up to working pressure and check for weeps before closing the space up
