Kevin,
I can tell you that you do NOT want even the
smallest air leak in your oil pickup. If you do the pump will find it
easier to suck air than oil.
Another aspect is that early rotary pioneer
had his engine seize because he was using an 18-24" length of rubber hose
for his oil pickup. It normally took a long time (approx 60
sec) for his oil pressure to come up after engine start and one hot day
the combination of the hot oil and hot temps softened the hose sufficient that
the pump sucked it closed - no oil to the bearings and the engine seized.
Fortunately, it happened after he was on the ground (after several flights that
day). It shook him up to the point he removed the rotary engine - although
it was really no fault of the engine.
I personally would only have metal or a proven
part in my oil pickup assembly.
FWIW

Subject: [FlyRotary] bad oil pickup
example
on the renesis engine I bought, the prior
owner (I forget his name) built a custom oil pan. this was the mod for
the oil pickup. I doubted that fiberglass would do well in a 200 degree
plus oil bath environment. with a cut-off wheel and a screwdriver the
fiberglass literally popped off. that would have not been too cool when
flying! I'm glad Bruce did the overhaul.
