fuel tank

[fishingwithblue]

Can anyone point me in the right direction in replacing a fuel tank in an 84 steplift cuddy. I just bought the boat and at the place where I bought it the guys were replacing the fuel bulb before the seatrial. I wondered if they spilled gas in the bilge during the process but not sure. When I looked at the tank through the inspection holes it looked original(metal) and a somewhat suspect to be leaking. Advice?

Dumb question: should I not run it until I find out if there is a leak?
