Andrew,

                    What is gates barricade hose?  Know their V belts well, but did not know they made hose?  I bought all my stuff from a sydney mob that  sold fittings and all hoses.  Cost me a few kidneys each time.

Basically a manifold with low & high pressure galleries, 2 walbro pumps, 2 filters, pressure regulator, pressure & flow senders, optical level sender in low pressure side and NC gas solonoid to allow vapour lock release (never needed yet) and fuel transfer (used to empty last fuel from tip tanks into right main tank). also bleed back from high to low side under the regulator, just a drilled hole with a jet from a carby pressed in (relieves pressure after shutdown and dumps enough fuel so regulator can still cope just in case both pumps are on).
Fuel is stored in 4 wing tanks connected to valve from a Piper aircraft. through a strainer, boost pump (standby/transfer) then into low pressure side of manifold, out from flow sensor to fuel rail. for majority of fuel lines I used Gates Barricade hose.
If boost pump is off and the solonoid valve on, it does allow fuel flow back from right main into manifold, bypassing selecter valve, strainer & boost pump. obviously this mode would only be used in an emergency.
Everyday use is very simple. select tank, turn 1 pump on. go fly. have not had to use boost pump before or during flight.
