Try taking off the skit plate first. There's a drain plug on the bottom that sometime leaks.
Does it leak when it's low on gas? if yes, it's from the sending or return hose. If not, it's the pressure hose. Best is to drain the gas, clean the outside then put everything back. You can surely tell where it's leaking from.
I had a leak recently because the guy that moved my tank to the back didn't leave enough clearance ( just 1/2 in. more )so the sending nipple was pushing up on the body cross member. I just used JBweld and snipped out some metal to clear it.

With all that dirt build up, it's hard to tell where it's leaking from.
