Porsche 924 Scheiße - knackered fuel accumulator?

aaaand we now have a fuel leak on the fixed pipe:

Bollocks.

Pipe is long and NLA. It's also holed in the section that curves up next to the heelboard that you can see, then passes over the top of the rear axle, so a tricky shape.

Plan is now to buy a couple of these: https://www.screwfix.com/p/flomasta-brass-compression-equal-coupler-10mm/37293 and make up two stubs of 10mm copper pipe with flares on the end, then join to two with fuel hose and clips to remove the damaged section.

I have no flaring tool to do flares on the car, and the one I have is crap at the best of times. Not good enough for brakes, but should manage something which will stay fuel-tight here.

Was just catching up with this, saw big stillsons, bit of a fight and fixed fuel line all together in one post had a horrible feeling what was coming next - and it did. I always get the same issue with brake lines - touch it and poof, a hole appears  

Your plan looks fine though - can’t help with the diameter question, but if you do it in 8mm and you end up with poor  performance at high revs you’ll know what needs doing!

I know! Although weirdly, nothing I was fighting with would have moved the bit of fixed pipe that's leaking, so 🤷‍♂️

Anyhow, much easier to do this now than have a fuel line explode on a rainy January evening somewhere horrible. That section is really rotten, so I knew it was coming sooner or later.

This is what the shakedown bit is for, after all.

Will try to replicate in copper, but got some 20 bar rated fuel hose ready for if it's beyond my limited skillz.
