Steps to remove your Volvo 850 Fuel Pump
The Volvo Fuel pump is located in fuel tank. Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE. On station wagon models, lift luggage compartment floor cover and fold back carpet. On sedan models, tilt right rear seat forward. On all models, remove luggage compartment carpet and right wheel housing panel.
On some versions with a soft panel, it may be sufficient to fold back a corner of the panel.
- Remove cover above fuel pump collar.
- Disconnect fuel pump connector.
- Carefully disconnect quick-release couplings on delivery and return lines.
- Remove fuel pump collar.
- Lift out fuel pump.
- Remove rubber seal.
To install, reverse removal procedure. Tighten fuel pump collar to specification.
WARNING: If the volvo fuel pump is removed for a long period of time, reinstall fuel pump collar to avoid tank swelling. If collar is not reinstalled, it may be difficult to install at a later time.

I was driving to work on Thursday and my 1996 850GLT (170,000 miles), which has always ran great, sputtered to a stop. It would turn over every time I started it but I could only go about 30 feet before it died again. I was about 50 miles form home and right across the street from a little hokey shop that I’ve bought tires from but never thought I would ever have any real work done there. They changed the fuel filter to no avail. They’re telling me it’s a sensor of some sort but still haven’t fixed it. I’m worried that they can’t handle it and I’ll end up having to get it towed back home.
