    Metal fuel tank connectors, PTFE tape?

    As many others before me have done I managed to break the plastic fuel connectors on the tank.
    I have replaced them with the metal ones, but one of them is weeping petrol.
    I know petrol is a bugger and it will leak at the tiniest opportunity so do I need use PTFE tape or some other sealant,
    or just screw it in a bit tighter. I noticed the connectors had a slightly tapered thread.
    Any previous experience would be appreciated.

    Make sure the o-ring on the connector is not damaged or pinched. You should not need anything like thread tape.

    Well, after having a good fiddle around and disconnecting the fuel lines I found it was the new female fittings on the tank that were leaking.
    I tried tightening them more but still no joy so tried the PTFE tape on the threads and it worked a treat.
    The original plastic fittings would have probably 'squished' up a bit and sealed the joint but I always suspected the metal on metal threads wouldn't stop
    petrol leaking through even though they are tapered.
    Not sure how PTFE tape reacts with fuel, but I'll keep an eye on it.

    Not sure if PTFE tape is pure PTFE or not but the PTFE itself is fine with fuel and pretty much everything.
