square seal for my epic

[Bananabus]

Hello transit world. Had my banana bus. Not just the engine it's a coach built on a twin axel.flat bed, and it's yellow.lol. had it about a year and been reading the site for all sorts of clues brilliant and thankyou. Can anybody please let me know we're I can get the square seal for my epic Lucas leak.
Just smelt diesel today and noticed a puddle of diesel on the floor when parked. Also it's a constant drip at the moment but also wondering how long will it stay before it gets worse. Many thanks.
