Before you start — fuel is flammable
Work in a well-ventilated area away from any source of ignition. Offer the new lines up to the vehicle and check them against the originals for length before removing anything. Drain the system, catch any spillage and keep fuel off the paintwork.
Fit using the new copper washers supplied, route without kinks or twists, and make sure every line sits in its original brackets and rubber bushes clear of the chassis and any moving parts. Bleed the system per the manufacturer's guidelines with fresh fuel, and check every connection for leaks before driving. If you are not confident, have the kit fitted by a competent garage.
Remove the original nuts and olives
On the hardline tails at the fuel tank, lift pump and injection-pump return you will find the original nuts and olives that took the OEM fuel lines. The new Pioneer 4x4 fittings use a different thread, so these must come off.
You can carefully cut the olive to free the nut, but this risks damaging the tail — we recommend fitting new parts to take the new nuts and olives.
