Cant drain fuel slump (Comanche)

[Kilstorm]

Something new. During my walk around in P3Dv4.1 doing my preflight checks, I could check for water in the wing tip tanks but the main fuel slump was greyed out and I could not click on it to check for water. This is a new issue that I have never seen and have in the past been able to check that. I havent tried it again after restarting the sim but just curious if anyone knows what this is about.

I don't use P3d but I did have that problem in FSX and all it was is I didn't turn on the fuel valves in the aircraft before I did my walk around. Hope this helps.

Hi.
Tug is correct in what he is saying , if your engine fuel check is greyed out , you just need to go into your aircraft and turn the fuel valves to wings , i dont have P3D but it should be identical in all sim versions , i have FSX+ACCELERATION.

God I love accusim. That would be it. I knew it wasnt a bug but couldnt figure out what was different.

Glad that it worked. Happy flying.
