## ⚙️ Key Features

-   Supersedes 6605038
-   Old number was listed only as a spare part
-   49 applications across six engine series
-   Fuel System group part

## 🔌 Function

Seals the joint between two fuel system faces so pressure is held and air cannot be drawn in.

## ⚠️ Common Signs of Failure

-   Fuel seeping from the joint face
-   Hard starting or an uneven idle from air entering the system
-   Gasket found hardened, cracked or flattened out of shape on removal
-   Witness marks or fretting on the mating faces

## 🛠️ Service Notes

-   Treat as single-use and renew whenever the joint is disturbed
-   Clean both faces back to bare metal before fitting, as old gasket residue is the usual cause of a repeat leak
-   Fitting 76753 at the same time is worthwhile if the fitting itself has been disturbed
