I have a Volvo Penta
md2002 from the year 1987 installed on a beneteau
first 305. I am very new to the boat and the engine
. Upon inspection
I found that there are four hoses coming out of the tank.
1. Thick rubber, on top for filling up fuel
2. Thin rubber, on top for venting
3. Thin copper, below to the engine
compartment (guessing this is the fuel
intake for engine
4. Thin copper, on top. ?????
The fourth one I don't understand what it is. It is also going to the engine compartment but it is attached to the tank on top so it must be some kind of return?
If anyone knows, I would appreciate the help! Thank you.
