In addition to that I buy Viton o-ring, Dash 247 as a substitute to the stock o-ring. It costs around $11 for five from McMaster Carr and is re usable should you have a situation out on a ride and need to get into the tank and then put the pieces together.

Are these truly reusable? Fariborz (?) has a horror story about trying to reuse the Ducati brand O ring.
