Dan,
Fuel Line:Summit P/N SPE-29310 - SSteel-Flex, Braided Stainless Steel, 5/16 in. Diameter, 10 ft. Length, Each$36.95
Oil Lines:Use 8AN push lok fittings. (Aeroquip work best for me)
Summit P/N Aeroquip FBM1533 - Aeroquip Socketless Hose End, 90 deg, Each $17.95.
Summit P/N Aeroquip FBM1513 - Aeroquip Socketless Hose End, Straight, Each $6.95.
Use 8AN push lok line. I purchased mine from my local Motion Industries store, LOLA+ Black Push-Lok Black Hydraulic Hose, P/N 3284-2504, paid $1.12 per foot. Good for 300 PSI with flame resistant cover.
I would not recommend using the blue Aeroquip socketless hose for either fuel or oil lines as additives in fuel cause this line to become hard and brittle and elevated oil temps cause the same thing. Remember to assemble line to socketless fittings with both hose and fitting lubed with oil.
Hope this helps!
