The fuel lines within the boot space are made of a hard, opaque, white nylon and exit via a union mounted on the far right of the rear bulkhead. Metal piping is then used between the union, around the rear axle mounting panel and along the underside of the chassis, to the fuel filter within the engine bay.
The filter and union just needed to be cleaned up. So the alloy body had the ultrasonic cleaning treatment to remove the fuel residue and the other parts zinc-nickel plated. Leaving the difficult part of bending the Cunifer fuel pipe ….
A 5/16″ diameter pipe is used for the fuel line so it is less forgiving than the brake pipes if minor tweaks are needed. The difficulty is that the entire section around the rear suspension cage needs to be bent into shape before it can be offered up. This involves bends in a variety of different planes, a sharper bends to then pass along the underside and ensuring the pipe passes through two retaining clips.
Fortunately I still had a slightly deformed original pipe to use as a template otherwise it would have been an altogether harder task. Again, as with the brake piping, I deviated from the original routing around the bolts for the torsion bar reaction plate. The only bit I’m not entirely happy with was the small section of pipe from the inline union in the engine bay to the filter which ought to be more horizontal. Still, it’s hidden by the vacuum tanks so shouldn’t stand out.
The good thing is that, now this pipe is in, the completed rear suspension cage can be fitted. Half way to a rolling chassis!!
Below are a few photos of the pipe routing:
