leaky fuel tap

[twisted]

hi guys and girls any ideas please. i bought and fitted a new kingsportster tank and fuel tap to my trike but there seems to be a very slight fuel leak from the tap. i think it is from the thread and not the tank or tap itself. any ideas on a fix? do you locktight the thread, ptfe tape or rubber washers? cheers for any replies.

Hi you can try anything the main thing is that you will have to empty tank and make sure all is dry before you seal it otherwise petrol will find a way through .

if its a taper thread PTFE should do, but if it is a parallel thread and the tap has a shoulder and winds all the way in, a fibre washer is the way to go.

Mine have been the old style with left and right hand threads pulled together by a special nut. These I have used with a rubber/nitrile washer and never had a problem. Main thing is not to turn the tap when tightening.

cheers for the answers. will took it off and have a look and see what i have .

the trick with the right n, left handed threaded tap fittings is to get the threads set up evenly before putting them together its easy once you know how but hard to put into words ==just study it well

Cheers for the pointers.  Had a good look and a few tests and it wasn't the tap leaking.  It ws coming from the recessed area around where the tap goes into the tank. So drained the tank, dried it up and pushed and mold some metal putty into it. All dry and no more leaks now  thanks again.
