I have been reading the discussion about fuel tank systems. I fly the
Firestar 11, and found the same problems with the top fuel draw system. The
aircraft fly's with the tail high, so the tanks are not level in flight the
rear tank will run dry before the front one will, and as soon as the the
rear tank runs dry and starts to suck air the engine will stop due to fuel
starvation. So I decided to go to the bottom delivery system. I personally
did not like the rubber push-in tank grommet in the bottom of the tank, I
must say I have never heard of this system failing, but I did find this
"Tank Access Bulkhead" in CPS cat. p/n 8561for $12.95 and the "Threaded
Hose Barb" p/n 8521 for $1.59, for me to have piece-of-mind that is was
screwed together and it made it easy to add a gascolator too.
Fly safe.. Tim

Some years back someone posted of a way to empty the rear tank
first by not venting the front tank and running a fuel pickup thru the
top of the rear tank into the top of the front tank then venting only
the back tank. It will empty the rear tank first then act as the vent
for the front tank. Who ever it was said it worked fine.
Just a though!!

Not to beat a dead horse but I have a Flightstar IISC in the shop for an
annual right now. I was in the process of rewinding the bungee cords on the
main gear and had to move the fuel tap on the bottom of the tank to get
access to the left main gear. All I did was twist the push in fitting
slightly and it began to drip gas. Nothing I could do would stop it once it
had started, yet I could see no evidence of previous leakage. I drained the
tank and removed the fuel grommet. Sure enough, it was split. I guess all
it took was moving the fitting to finish off the split. Thankfully I had
new grommets in stock and it didn't happen while the owner was out flying
around as there is no fuel gauge in the aircraft.
Not that bottom taps are bad, they're just one more inspection item.
