If I may, w/o having researched the circumstances myself - an important consideration may depend on the type of AN hose that you use and the method of attachment to the fuel nipples at the switching valve and pump. Oxygenated fuels (that is, fuels that contain alcohol) are aggressively corrosive and very drying to many SS hose linings, resulting in premature aging, cracking, and fluid leakage. Linings made from rubber are especially susceptible to accelerated decay. PTFE lining is, perhaps, the most tolerant of oxygenated gasoline. That being stated, it seems to me that you should research thoroughly the most suitable hose types along with safe and secure hose attachment solutions before committing to the investment and potential risk. A simple hose or fuel injection clamp may not work with all AN hose types. Another consideration is that the SS hose should be routed and secured such that it cannot rub against any other lines or wiring since the SS braid is very hard and abrasive when compared to most other automotive materials. SS braid can actually saw through adjacent steel lines and other SS hoses when allowed to rub against them for a long enough period.
