2000 38 Lightning. Through every body's help I know my tanks are roughly 90gal and there is one for each engine. Is there only one fuel pickup or are there two? My gauges were not reading properly so I ran out of gas and when I put gas in one engine did not crank. I put 45 gallons in that side and then topped it off with 15 more gallons once on trailer. I'm no mathematical genius but that's only 60 gallons. Hence the questions for 2 pickups for fuel. Could someone please shed some light on this for me?? Thanks.

What engines do you have? For the year of your boat- the mechanical fuel pump (if equipped) is linked to the sea water pump and they are known to fail, no fuel pressure no startie

Also after running dry on fuel the filter/water separator may have to be primed if it was ran completely dry to ease with restarting, but my guess is you had a fuel pump failure.
Did both engines run out at the same time? Because that would be extremely rare, mine are never equal on fill ups.

Each has its own pick up, and fill, and they are not linked. The hoses come out in the engine bay, and may have shut off valves on them, then they lead directly to each engines fule pump. My 04 has twin 115 gallon tanks. The gas gauges are worthless.
