Fuel pump O-ring seal positioning?
My 08 speedie is leaking fuel , by the looks its from around the fuel pump.
So, I took it apart , the o-ring "looks" ok , but i have ordered another one just in case.
My question is, i noticed the O-ring has a groove in it, is it meant to be mounted on the rim of the tank itself (in the groove)?
or just sit on the underside of the tank with the base of the fuel pump pressed against it ?
thanks for your help.
(PS, the current one was NOT mounted on the rim.
