Nope, one of the newer style tanks. Pick up tube and check ball have been checked.
I promise I'll update this thread once I install the on-demand valve, reposition the bulb, and replace the fuel connector with a Mercury OEM. Life has been busy and it may be a bit yet before I get back to the boat. Thanks again for all the help!
Another factoid on orientation of the bulb. I use a fuel hose with a bulb to siphon diesel fuel from 5 gallon jugs into my tank. I get the siphon started by using the squeeze bulb. The other day I was doing this and I couldn't get the siphon started with the bulb oriented facing down or horizontally. I then placed it so it was vertical at the mouth of the jug with the arrow pointing up and with two pumps it pumped fuel and started the siphon, so there is definitely an advantage to the orientation. This is not to discredit other posts here about air leaks and such, but this experiment really showed a difference in performance of the bulb.
Great thread. Been around engines all my life and still pick up on little tips and ideas from threads like this one.
I'm going with getting the bulb vertical. I had similar problems and went through three hoses and two tanks before figuring this out. The other perennial problem I've had is that the plastic gizmo that holds the emergency stop button out vibrates out of position a little so it looks like it's working but isn't. If it weren't for safety measures my engines would be perfect.
