boybach wrote on Tue, 20 July 2021 02:51All the fuel lines have been changed, incl. gen so I don't think it's that. The genny usually runs just fine as it did after I gassed up. Could I have been low on gas after a 250 mile trip and a few hours of genny use? I was pushing the 403 pretty hard up the hills. What is the range of the coach?
I appreciate the float travel is limited but shouldn't I have some movement on the gauge after putting 15 gallons in? Is it normal for the fuel gauge to show true fuel level with ign off, key out and even after battery is disconnected?

Larry,
Let's look at all of this. You say you are hard pressed to make the 8~10 typically referenced. That is very believable. Let's (just for the discussion) say you were running real close to 7MPG. ~250 miles, if the tanks are the same level, then there is less than 15 gallons between them. At 7 per tank is real close to the 6-1/4 when that is the quarter tank mark. Please note: I know for a fact that the quarter tank as written is just an approximation...
If you did not carefully watch your fuel inventory, there is a very good chance that you were at less than the magic quarter tank...
And NO....
If you read the first line of what I answered to your first post of the thread, the Delco instruments of the period (and for many years after), fix where they are when the power goes away.
There is also an interesting feature in the fuel system. A consumer motorfuel dispenser (aka gas pump) spits out fuel at a maximum of about 10 GPM. If you are fueling a box stock TZE with a normal pump, between the fall from the fill neck and the pumps velocity, most if not all of the fuel added will go to the main (rear) fuel tank. I have done this myself and there was a demonstration of the fact at one of the internationals.
