# 3808703 Hose | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta cooling hose with a 1.25 inch inlet, weighing 0.862 kg and listed for 2 applications. It supersedes part number 3862845. Hoses 3808670 and 3809151 carry the identical 0.862 kg published weight, so the 1.25 inch inlet and the part number are what identify this one.
