Hi guys,I have ver 1.22 installed and have searched through this forum and through the readme (RW fuel pump behavior) but...I'm still having a weird problem. Whenever I fuel the aircraft, no matter how much gas I put in each tank, the center fuel tank empties down to zero. I am stumped for an answer. Any help would be greatly appreciated.

Try manually putting the sim on pause first before changing the fuel. This should force the panel to reinitialize the (externally modelled) fuel system with the new quantities when it comes out of pause.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Will do, thanks. FYI, I noticed that when I refuel during a flight, there is not a problem, so what you suggest makes sense. I'll let ya know. This is an AWESOME airplane!!! Thanks for the help!

I have the opposite problem. If I try to reduce the fuel from full to a lesser value, when I return to the flight the center (or wing) tank fills back up of it's own volition. The only way I can to make it stop is to change the value in the fuel percentage window rather than the value in the pounds window.

The TM II is a bit tricky to fuel, like some other addons I have. Many times I get an error message that the quantity must be between XXXXX and XXXXX lbs...even when it is. One thing I've done is to use the percentage number exclusively. I make ONE change, then click "OK", then re-open the fuel window for the next change. Works most of the time.

The panel reinitializes the fuel system (which is modelled externally) when it sees the sim coming out of pause. The fuel system is actually modelled independently of FS and every 5 sec or so the panel writes the new fuel quantities out to FS to get the w/b right.The percentage window may or may not work, same as the lbs selection. But changes made in pause mode should be reliable.CheersBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Works most of the time.Yes, this is a FS bug...believe it's a function of fuel quantity computations being rounded. But 100% can do the same thing. If I have the problem, I drop the qty about 10 lbs below the listed max and that seems to work OK.CheersBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Yep, definitely an FS bug and in no way the fault of all the fine addons which experience it! Vic
