Brake & Fuel Lines - Replacement

Hi, I'm shortly going to be replacing my brake and fuel lines and am heading to the motor factors tomorrow morning to buy parts.

Can anyone please give me a list of what's needed, with dimensions too?

Supply pipe 5/16" = 8.0 mm (1 front to rear)
Return & vent 1/4" = 6.3mm (2 front to rear)

Brake pipes are 3/16, if you are changing the fuel pipes, the brake pipes will be shot too. (2 front to rear)

Boxfull of brake unions: threaded right to the end BP9 rings a bell

On mine the supply & return pipes were flexible plastic from the tank to the steel pipes, so I ended up leaving 15mm of steel pipe sticking out to join to, rather than drop the tank and discover that I couldn't connect at the fuel pump.

Fuel injection hose 1/4" ID & 5/16" ID plus clips to match

New plastic clips to hold to chassis, or some really long Zipties and as many of the old ones as you can save.

Thanks facade, good info

For the fuel lines, can I also use the cheap copper type as for the brake lines, or must I go steel?

Copper is fine, AFAIK it doesn't react with fuel. Fuel pressure is way below brake pressure.

Be careful to secure it though, as copper work hardens and snaps if it gets to wave about under vibration.

Burst a brake line at the last off road event, a pin hole just as the pipes turn above the rear spring. Cut it, hammered it flat and bent it over to get home with front brakes only.
Both pretty rusty so took them off at the weekend but disturbed a fuel line which are in a similar condition. I've ordered 10m 8mm plastic covered microbore plumbers copper pipe to replace all three. Going to try cutting a "hatch" in the floor above the fuel pump rather that drop the tank as I'm fairly sure all the bolts will be rusted and break. The two inch body lift makes it much easier.
