My 928 also used to leak petrol. Replacing the fuel lines was a 2 week
job and far from easy. My suggestions are:
1) Don't do this job unless you are an experienced mechanic with plenty
of time on your hands
2) Buy a mini pipe cutter and a pipe bending kit before you begin
3) Don't use metal flares, they leak no matter how hard you try to make
them - instead use rubber pipe ****elded on the outside with copper
piping for the joints.
4) Now would also be a good time to plan to de-rust your fuel cradle
that costs a fortune to replace.
5) Try using copper because 10 mm Cunifer was a bastard.
6) Remove battery and drain fuel tank from the line next to the fuel
pump. Note: there is a lot of petrol left in the lines even once tank
empty.
7) There are a LOT of things attached to the fuel tank! Prop up the fuel
tank using blocks of wood or a jack in order you don't rip out
lines/connectors etc.(You remove the tank by undoing the fuel cradle
bolts & disconnecting the screws holding the tank in (see workshop
manuals, I think there were 3 or 4) and undo the connectors to the tank)
8) Use the mini pipe cutter to cut a section of the steel pipes
somewhere under the car where they are no longer rotten. Then use bolt
cutters to chop out the length of pipe (remember the comment about LOTS
of petrol being in the fuel lines)
9) Replace pipe with copper/cunifer use pipe bender to make the job
slightly easier. Warn the wife/significant other/cats & dogs/kids to
expect lots of swearing. This task will take MANY hours.
10) Fix up fuel cradle - wire brush then hammerite it. Put things back
together (once again easier said than done - the tank is a very tight
fit) and voila.
Joe & others who intend to do this job - email tom (dot) Skelton (aaat)
gmx (Dot) co (DOT) uk and I'll send you my journal piece on it.
