It is fuel line that is impervious to the aromatics in the fuel. In effect fuel cannot seep through it like it does in older hoses. So, good to use if you need flexible lines within the cockpit. Available for efi or low pressure (I just use the efi stuff for everything) Also they have option for submerged hose but dont need that unless hose is inside tank. Any tractor supply or Gates belt supplier can get it for you, I'd just bet they never heard of it so you have to be persistent. I use it because it just seems better quality than anything else available here, and it stops that horrible spilt fuel smell you get when opening the hangar or when first getting in the plane.

Hi. not sure if I've posted my fuel setup before, but attached is a picture of the pumps during testing prior to installation. Has been in for awhile now and seems to work well. basic idea was for semi returnless and to minimize piping & joins, as they are my nemisis.
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.
Andrew
