What would be best type of fuel line to use for replacing the fuel line from front to rear on a mini .
I need to replace the fuel line from 1/4 inch to 5/8 inch and also run a return line to the tank.
Would copper tubing work ?
How much tubing would I need to do it?

Just cause it says it is for a mini ,doesn't mean it will fit a mini......

1. Do not use copper for fuel or brake lines, it work hardens with age and vibration, then cracks.
2. Surely you mean 5/16", not 5/8"...
3. I bought 4M of aluminium coated? steel tube off a roll at Robbos Spare parts years ago, I dunno who has it now. It bent pretty easy. Try someone with brains, like not Supercrap...

Is it called "bundy tubing" different to what doc said but it is good for fuel.

Respect mine and I'll respect yours.

yeah i normally use Bundy tube & then use a sheath of fuel hose over the top of that,,, keeping both ends outside each front & rear fire walls,,, that way even if somehow the bundy tube cracks/snaps/tears the fuel still can`t get into the cabin

Repco sell rolls of the tube & rolls of fuel hose

You should put your heart & soul into everything you do.
