not really worried but just wanna know what im gettin into beforehand!

Thanks for the support.
As they say "You know what you have."

So you got me thinking and when I got gas this weekend I watched the gallons in each tank. Starboard front tank runs the center and starboard engine to fill it I put in 28 gallons. Port tank runs port engine only and it took 25 gallons. Both tanks were full before I went out last time. How does that work? I'm going to watch the gallons again next weekend when I fill it.

we had a 99 trip 42 with the same power and all 3 pulled from both tanks it is normal for one tank to take more gas .they should be connected

Did you have a total of four shut off valves for the tanks too?

Mine has 4 valves and the engines pull from all 4 tanks.

So you can run the three engines of any of the four tanks by shutting down three valves?

Yes, That is correct.
