## ⚙️ Key Features

-   D13 low-pressure fuel-system connection
-   Correct thread and sealing shoulder
-   Internal bore sized for pump supply flow
-   Machined hose end prevents leakage and air ingress
-   Used with hose 21163011 and pump 22677520
-   Engine type: D13 low-pressure fuel-pump and filter system

## 🔌 Function

Provides the sealed transition between the D13 fuel pump and its connected low-pressure hose.

## ⚠️ Common Signs of Failure

-   Unstable idle, misfire or reduced power
-   Fuel leakage or air ingress
-   Injection or fuel-pressure fault codes
-   Excessive smoke, combustion knock or uneven exhaust temperature

## 🛠️ Service Notes

-   Check the bore is clear before fitting — a nipple is often the feed point or restriction for a circuit, and debris left in it will starve whatever it supplies
-   On tapered threads use the paste or liquid sealant specified for the fluid concerned, applied a few threads back from the open end; avoid thread tape on fuel and oil lines, where a shed shred travels downstream into filters, pumps and injectors
-   Where the nipple seals on a face or against a washer rather than on its thread, fit a new sealing washer instead of curing a weep by overtightening
-   Tighten to the figure in the workshop manual for your engine — these are small fittings in castings and are easily stripped, or the surrounding boss cracked
-   Support the pipe or hose so it meets the nipple square and without side load, then check the joint at working pressure and temperature
