-   Part of fuel feed pump 20450901
-   Confirmed across D5 and D7 fuel systems
-   Used with sealing gaskets and hose connections
-   Should draw fuel and hold prime without leakage
-   Engine type: Volvo Penta 5- and 7-litre mechanical diesel

## 🔌 Function

Manually draws diesel through the filters and feed lines to remove air and restore fuel prime.

-   Hand primer will not draw fuel
-   Fuel leakage around the plunger

## 🛠️ Service Notes

-   Part of fuel feed pump 20450901 — order the feed pump assembly reference if the priming section is not sold separately for your engine
-   Check the suction line and filter seals for air ingress before condemning the pump body, and make sure it is locked back down fully after priming, since a pump left off its seat keeps drawing air
