I need to replace the gas tank vent hose, or whatever you call it. Where is the best place to get one and how difficult is it to replace? I was also wondering if anyone with an 855 has experienced all the locks locking when the rear hatch is shut especially when the weather is cold. I once had my 2 year old locked inside while at the recycling center, keys in ignition, phone in car, not cool. It seems to be a completely random event, happens less than half the time.

your probleem with the doors locking when the rear hath is shut,check the wiring
in the taigate near the windo washer nozzle.

How do you know it's a gas tank vent hose? If the dealer told you that, I'd be skeptical. Take it to an independent repair facility. Or better yet, just ask someone in a parking lot who owns a volvo where they take it. That's how I found my wrench (he works at my office!)

Maybe you are referring to the flame trap tube? It can cause an electronic code that signals there is a pressure drop in the fuel delivery system.

Hint: Next time take your keys with you, especially with a kid in the car.

Thanks that was a big help.

It was very careless to leave your 2 year old child in the car with the keys in the ignition.

The vent hose to the gas tank is not available as a part from Volvo - instead, Volvo will sell you a new gas tank with all the fittings ( about $400 plu $150 to $200 for installation).

There is a workaround - my indy volvo mechanic located the exact hose from , i think , a 940 Volvo.

Cost this route is about $200 - the fuel tank has to be dropped.
