Just wondering about something here. When you say "3 blinks in a row", are you looking at the ENTIRE blink scenario? That is, in most cases, the blink sequence is followed by a short "pause" then, there is another set of blinks then, a long "pause" then, the sequence starts all over again. I just want to make sure we're on the same page here.
When I had issues with my Onan 7.5QD shutting down prematurely, it also blinked three times. But, it blinked three times and, like stated, a short pause, then another set of three. When I went to the Onan trouble shooting manual, that was a code "33". And, that code had various remedies. For mine, it was called an "over heat" condition which, Onan gave many possible cures for it in the manual.
But, none of the cures was the problem. On mine, and many, many other Onan 7.5 and 8.0 units, it's a faulty temp sensor.
Anyway, just trying to help analyze your issue here and make sure you're reading the blink-code system correctly. If you are and, your unit is actually shutting down because of low fuel when in fact, you DO have a half tank, then yep, some investigating is in store for you.
How long have you owned the coach? This question pertains to, if your gauge is accurate, then you know what the tank is supposed to hold. And, let's say you fill it, then, travel long enough to put an estimated amount, based on what the gauge says it is at the time. Let's say it's a 100 gallon tank, like ours. Then, you drive it for say, long enough to have that gauge read 1/2. Well, now you should, for the most part, be able to put 50 gallons in it, plus or minus just a couple.
So, see what I'm getting at? If you've drove this coach long enough, you should be able to estimate real close, just how much fuel you're going to put in, based on where ever the gauge reads at the time. That should tell you how accurate your gauge is. Good luck.
