Complete idiot question don't make fun lol
 

I have been rerigging and repowering a 1996 38 thunder all winter. We are finally ready to fire and hopefully water test today. I sent one of the shop guys to put fuel in it up the road. When he comes back I asked which fuel tank he put it in and he wasn't sure.

On fuel gauges on the scarab/wellcraft 38 ......is 1st gauge the left aux tank? center gauge main tank? and 3rd gauge right aux tank? The left gauge is full, kind of thinking he filled the left aux tank....which brings me to question number 2...if he did fill the left aux tank do they gravity feed to the main tank? Is there a way to transfer from aux to main. Sorry last fountain simply had a left and right tank lol.

Thanks for any help and sorry so dumb on the fuel system of my own boat!!!! If all is well this weekend,, I am headed to LOTO next weekend so I need to know what is what for that trip as well.

I can’t answer your question but someone will.

How much fuel did they put in the boat?

time for a new shop guy........:D........call Dan Archer Archer Marine ( Team Archer ) on here he knows these boats

no the tanks don't gravity feed to each other. they have a valve that you switch from tank to tank it's a manifold in the engine room.
