Just replacing all existing fuel lines on my Streak Shadow, and interested in peoples ideas.
The current system draws fuel from bottom tank (under cockpit) thru a filter, into a primer squeeze bulb, thru to mikuni pulse pump driven off the Rotax 582, into twin carbies. So, fuel is drawn from below engine, and the squeeze bulb is just used for priming.
Question 1: I was thinking of putting a second line around the squeeze bulb in case the bulb blocked during flight, but seeing as I only use the bulb for priming, would it be better to put a Facet cube pump (in series) in place of the squeeze bulb, as this would:
a) allow me to prime from inside the cockpit (lazy, I know), AND
b) could be used as an emergency backup for the engine driven pump.
NOTE - The primary purpose of the new Facet would be only to prime the fuel lines, and not used after engine start.
Question 2. If I use a Facet pump IN SERIES, would it be recommended to use this on takeoffs and landing as well?
Question 3.
The Streak uses clear plastic tubing as a fuel level indicator for the top tank, which sits below the engine, and also as fuel tank vents. Tubing is rock hard, and need replacing before I fly. Is there a particular (best) brand of clear tubing (about 1/8" internal diameter) I should be using as a replacement?
Thanks in advance.
