Hi @mrmrmartin -- can we please discuss commissioning of the bladder (i.e. filling it for the first time)? Some thoughts:
Only when testing has been completed should the bladder be filled to capacity.
Hi @mrmrmartin and @Christopher-w-green. I've had some further thoughts on commissioning the bladder.
I think we should initially test the bladder by filling it with AIR, and NOT diesel fuel. I recommend:
With this done...
Only when this test passes should a test with diesel fuel (see my previous comment) be considered.
Hi @Christopher-w-green
When we first test the bladder with diesel (Sydney, next week) it could leak from one or more of the fittings -- a situation that will required the bladder to be completely emptied prior to repair. We need spare capacity in the fuel tank (and/or the gerry cans) to accept the fuel from the bladder.
Could you please consider NOT refuelling in Shellharbour and, instead, run down the fuel in the main tank. The aim would be to arrive in Sydney with minimum fuel in the tank. There is a reserve of fuel in the Gerry cans on board (80L I think). That could be transferred to the main tank if required (leaving one or more cans empty).
You will want to avoid running out of fuel during normal operation of the engine. The faulty fuel gauge is not helpful in this regard.
kind regards Steven

Ok. Not having to use the motor much. About an hour yesterday.
Got a missed call on the tablet yesterday. So that was you, then.

Hi Michael,
I've arranged for Ivan Tesvic to come to Trilogy on Monday afternoon to help with the fuel bladder. Ivan is Diesel mechanic with long experience in navy submarines. He can help with any remaining issues. Or, if everything is sorted, give it the final tick of approval.
His contact details are
ivantesvicmarine@gmail.com 0418 462 646
@pauljones17 and @Christopher-w-green will be interested. @mrmrmartin
@mrmrmartin reports that the bladder has been tested overnight with air -- no leaks. Today the bladder was tested with diesel with no leaks
This is a great outcome -- well done Michael. Closing this issue
A lot of work has been done on this by @mrmrmartin. I'll capture the email trail in comments at a later time.
