2012 S40 How to replace a fuel pipe?

Post by v4vlv »

I noticed yesterday that my Volvo’s D4162T (1.6 turbo diesel) engine has been attacked by mice (or any other kind of rodent)! They have eaten the insulation foam of a fuel pipe. Even the pipe itself has marks from their teeth!
Probably it took place at holidays during last summer, but I noticed it just yesterday.
If I’m not mistaken the part number is 31355833 and you can take a look here:

(number 21 on image).

I’m thinking to replace it myself. What measures should I take to avoid excessive fuel leak during replacement?

Remove the fuel relay and crank the engine 2 or 3 times to burn off any pressured fuel in the fuel system.

As mentioned, there could be some resilient pressure inside the fuel lines. Sometimes having the car rest for a few hours will have the pressure released. On gasoline vehicles there is also a pressure releasing valve near the fuel rail. Just have a rug or even a can when disconnecting the line, there should not be too much diesel pouring. Watch for your eyes, glasses are a must. If you have particular questions about the diesel engine, you may also try on an european forum, such as http://volvoforums.org.uk/ .

Thank you both for your replies. For the escaping fuel I'm thinking to use an open can and collect it if the pressure is low as mentioned. I want to avoid emptying all fuel lines and allow air entering in a places which is difficult to bleed.
While I was searching for this (bleeding air from the fuel lines) I found that others have used a hand vacuum pump connected to the output of the fuel filter and suck the fuel all the way out. This is OK for the fuel lines before the fuel filter. What about those after? How should I bleed them? Probably a small amount of air will enter the circuit after the fuel filter during the pump connection.
