refitting fuel level sensor

[grant71]

hello. i am refitting a newly bought used fuel level sensor in my 86 K100 RS.advice i need pse is: does the round rubber seal( its new ) need any kind of gasket type sealant to make the fuel sensor plate and fuel tank connection leak proof. thanks

The gasket (o-ring) itself should be enough, no sealant needed.

This pm i started re fitting my fuel pump and the rest inside the tank. For a 1 st timer what an exacting job. I have a small problem. I cannot get the thin plastic tube  from top side of tank to the bottom of the pump next to the  small sieve like filter on. Is it a train smash if i leave it off ?
