My ship didn't come in, BUT.....

This question has been asked for years!!

The tank with the shortest hose will draw first.
The suposed way to fix this it to make both tanks have the same leanth hose and the same leanth hose for the vent. This way the perssure is the same in both tanks.

I have done this and they still don't drain the same.

I now have 3 tanks and I have put a 3 way vaue so I can switch from tank to tank.

I like this set up as I can see how much gas I use each tank, and in the case one tank goes empty I just switch to the next tank, alerting me to how much gas I have left.
