Whichever way you go, do a complete flow test when the system is installed. You'll want at least 1.5 times the max gallon per hour flow rate that you expect the engine to need at full throttle in any flight attitude. If you get that it really doesn't matter what we think. That's the only thing needed to keep the engine running. :-) Larry Flesner
