replacing fuel pipes

Hi guys, took my jimny 2001 model for mot today it passed ok, but the fuel pipes need replacing,
would it be ok to replace with plastic pipes?
cheers Garry.

Don't see why not, if they are rated for petrol and the correct pressure., and secured properly to the chassis.
Most people use copper or copper alloy pipes.

There are 3 fuel pipes on the jimny, 2 large and one small diameter.

A supply line under pressure, a return line and a vent line from the tank to the charcoal cannister under the bonnet.
They attach to the tank with some sort of push connector, and are a real pain to remove, the tank has to come down. The cheaters way is to cut the lines close to the tank and splice into them there.

TBH, the usual place they go is where they collect all the mud from the wheels, right at the bend under the drivers feet. You could cut this piece out and join a new section using proper clips and fuel injection rubber hose (like I have ) and it will be perfectly safe, and happily pass MOTs.

When I get A Round Tuit I will lift the body and change all the brake and fuel lines, but I suspect that that likely won't happen for many years

Thanks for your reply, i will measure them up and gets some of that HP black pipe from hydraulic supplier, i will have to cheat ,as you say the rot is along where driver is up against the chasis by footwell.
Any idea what pressure it should be?

The piece of rubber hose I have knocking around here says 225psi on it :ohmy:

Can't you just order fuel injection pipe for petrol and they supply the right stuff?

If you are going to the trouble of replacing it properly I'd use copper, you need a boxful of those plastic retainers too, you won't remove them without breaking them. (I don't trust plastic, it has a habit of going brittle and breaking after only a few years)

i though about the black plastic pipe as it has a reasonbly high pressure rating at 220bar, if copper pipe is ok and more readily available i will use that, just want to keep it neat and profesional.
