I done it on my GT last year, seams where gone, seems a common fault with starlets. Anyhow,
There's a few fuel lines to disconnect underneath, disconnect them at the side of the tank and not from below the seat as lines are bolted to the tank, filler neck and return, then the plug for the pump, that's under a panel below the back seat. Get the arse up and on axl stands, you may have to remove the back box but I managed to Manhandle mine out/in without doing so, definitely easier if you can split it, then it's just 4 bolts holds it in
Based on dropping my GT tank but can't see an ep91 being much different :)
