Hi guys
My Vixen was completed in 1999 and flew just over 100 hours prior to my purchase in 2009. It now has almost 600 hours,912 UL with IVO IFA prop.
I replace hoses by taking the metal nipple parts to my local auto parts store and going into the parts room and physically matching up "formed" hoses, both with correct inside diameters and bends and elbows that match the engine shapes.
Many replacement hoses on late model vehicles can be cut up to do a nice job.
I realize these are not aviation grade but so far it has worked well. Fifty dollars buys quite a few hose pieces.
