Hi,
Sorry, but I can't see the problem. In my 265, there never was any pressure in the
rear, i.e. the fuel lines to/from the tank. I just popped of the hoses and got the
pump out of the tank. Came a trickle just as the hoses came off, bot that's all.
Remember that the in-tank pump is just a pre-pump to the main pump located just in
front of left rear wheel. It's after the main pump the pressure builds, but that
pressure is contained from main pump and forward and doesn't kick back, and the
return hose is pressureless - more or less anyway. When the main pump stops, the
pressure drops quickly to nada..
