oil leak on my pto seal and gas guage is not working

[coolmike]

i have seadoo charllenger 05 rotax engine.recently I replace my carbon seal. i had to take drive shaft out to get to it. But when i put them everything back together am having an oil between pto seal and the outer circumference rubber.when i tighten the hose clap on the outer rubber will shrink.and the manual said the outer circumference should be flush with inner sleeve of to seal .Before i tighted the clamp it flush. but when i tight it won't flush and it still leak .should i push the to seal all the way engine or just flush with the outer circumference the is coming from seal is coming from between the outer circumference and seal .and my gas gauge is doing nothing
