Please use our superior quality PTFE tape each time that you (re-)assemble screwed connections in the fuel tract in order to properly seal the connection.
As an alternative, you can use our Loctite 243 Thread Locker which will offer the added properties of protecting your connections from undoing themselves.

We strongly advise you to secure your fuel lines using our Stainless Steel Jubilee Clips.

When using an electrical fuel pump, we also advise you to equip your vehicle with an Inertia Fuel Cut-Off Switch as a safety precaution.
