HS4 - 1500 - slight problem

Share this page

My fuel line is routed that way. A small clip was added to the air cleaner to keep it in place.

David,

Very neat!
I'll have to do something similar.

BTW, I've calculated that in less than 5k miles the cost the new carb will be recuperated in fuel saving. (assuming the mpg goes from the 22 mpg with the ZS to 30 mpg with this new SU and gas is $2.80/gal) Plus it has a lot more pep!

Cheers
 
Copper tubing is considered a no-no on brake and fuel lines. Copper wear hardens with vibration resulting in cracks and failure. You'r o.k for a little while, but I'd switch to steel. Better safe than sorry.
 
Kelly, I can see the concern over copper where it is supported at one or both ends in a rigid compression fitting. If the copper is secured at each end by rubber fuel hose would the same fatigue issues occur?

I've seen quite a number of brake line kits that are some form of copper-nickel alloy. I assume it must behave more like steel.
 
Kellyguy,

Thanks for that observation.
As Doug pointed out it might be OK if both ends are supported by rubber hose - the connecting piece for the HS6's on my TR3 is a big loop of copper tubing (as supplied by The Roadster Factory)

Next time I'm at the auto store I'll pick up some steel tubing though.

Cheers
