Pm outdoinit he got one made for the same purpose he could help.

 Cheers mate

 They arent cheap, can tell you that much! Especially if just for a one off run.

Jerries, unloaded onto the beach over there could be a better option?

I can't help with the fuel bladder but for a pump, Covs have an intrinsically safe 12v fuel pump for about 50$ we used to use in the workshops.  It comes with a screw in filter, you just need inlet/outlet hoses and to extend the wires, insulate and put some fixed terminals on the end so you can wire it to a buss bar and not have sparks from alligator clips.  Don't quote me but I think it did somewhere in the realm of 100lts an hour through a 1/2" inlet/outlet.  They may have bigger/faster models also, or you may be able to use an aftermarket or bosch car fuel pump.

Otherwise covs/veals/supercheap often advertise manual drum pumps with 1" hose, dunno if they would be easily rigged to a bladder though.  We took a 44gallon drum and manual pump in the back of a hilux while helping a light aircraft from Perth to Avalon, Victoria. We had two vehicles leapfrogging to meet the plane at airstrips along the way, I was only 11 at the time but even a kid could pump out a 44gallon drum without much issue into the wing tanks.

Hope this helps.

My conclusion on fuel bladder for extended trips was that it was too costly, fuel transfer issues and possibly with half full bladder would cause additional boat roll. I ended up with 10 X 10Lt plastic jerry containers that went into the kill tank and allowed them to stand up-right to avoid any leakage and now have another 4 X 20Lt plastic jerry's that will be positioned on deck to suit weight distribution for boat handling.

 Cheers for all the input guys was hoping for a bladder for room on the boat but it is looking to hard. Thanks heaps for that Bryan defiantly goin to get one of them

Hey Matty,

Have you looked into a permanent under deck fuel tank?  Scepter/Moeller do a range of under floor tanks that are baffled(pretty sure they are) you should be able to order these from boating outlets like Chivers as I dont think the supplier(I think Perth Marine Accessories 0408 833 665) or JPW/RWB Marine in welshpool deals direct to the public. Repco in Victoria are also listed as Australian Distributors.

If you plan to use it more than once try this:

They sell the bladder and pump, comes in at just under $600 for a 100L set up.

 Did look at that a while ago Bryan but I'm planning on selling the boat so don't want to spend that much coin on it but will defently be putting one in the next tub. Mike 74 I just got a quote back from them looks like the go made to size for under $600 

I had them make a stand alone system that fits in under deck storage, has lasted just over 12 months without drama and have been very happy with it.

Enjoy the extended trips to the Montes and Abrohlos.

 Be good to have even with the new boat can never have enough fuel bring on the Monties virgin trip for me
