How to change the fuel filter on a daewoo lanos
Your best choice would be to get a fuel line disconnect tool. I believe
daewoo uses the same type as those used on GM vehicles. Through
personal experience, I recommend being very careful as the plastic
disconnect on the side leading from the fuel tank can be very brittle
and easily break.
Sometimes, there is not enough clearance to use the disconnect
tool. You clamp this device around the tube of the fuel filter, and
push it up into the fitting on the fuel line. It's purpose is to
retract the 4 retaining fingers in the fuel line fitting which are
spring loaded radially. These fingers tightly grip a flange on the
filter tubing. From my own experience, I had to cut the fuel tubing at
the body of the filter with a hacksaw. Then you can see what's going
on, and maybe use the disconnect tool. I had to use a plastic sleeve
for this purpose that you can buy in a kit at an auto parts store
(about $10). Once the retaining fingers are retracted, you can pull the
end of the filter tube out of the fuel line fitting. Be prepared to
yank, pull, push, swear, curse, and maybe cry and pray. If you're
lucky, the rest of the fuel filter tube will come out, you won't break
anything, and your marriage will still be intact.
Good luck (remember rated this help).
