Volvo Maintenance Hints for 7xx/9xx - Bill Garland's Nuclear ...

used a torx bit on a ratchet with extensions to remove the screws to the valve that hangs down
in the way on the right side. I disconnected the small hoses surrounding the fuel filler hose. I
disconnected the hoses from the valve and set it aside. I disconnected the fuel filler hose from
the fuel sending unit. Using a combination of offset screwdriver and flexible driver, I
disconnected the fuel filler hose from the fuel filler tube. I then discovered that I couldn't unscrew
the clamp to the small hose and thought that I might be able to cut it off. As a last attempt before
cutting, I tugged on the small hose and it easily came off. If I had to do it again, I would tug on
the small hose before disconnecting anything else. Installing the new hose wasn't the easiest
thing in the world. The large section of hose fits tightly. Fit the hose over the fuel sending
connection. Leave it loose so that you can twist it into position to slip over the fuel filler tube. I
had to wiggle and push and finally got the hose to fully cover the fuel filler tube. When replacing
the valve, attach the hoses before tightening the screws. There isn't clearance to attach the
hose at the front of the access hatch if you tighten the valve bracket first. I would consider using
a different type of clamp for the small hose. Something easier to tighten and loosen. When I was
attempting to attach the small hose and clamp the first time, I discovered that the body dips
down and gets in the way of the clamp. A thinner clamp would be good. The hose was about
$45.00 + tax from the dealer. The part number on the new hose was the same as the original.
On my 93 960 there is a valve of some kind on the right side under the lip of the access hatch.
Its bracket is attached with two torx screws. I removed it to ease access to the small hose
connection.
