Many ultralights have no Facet pump.
The pulse pump does the fuel feed.
I have a different issue altogether.
My CG is at 12 inches back from Leading edge.
I had to add almost 6.25 lbs of weight inside the
rear fuselage, under the stabilizer.
This moved the CG back by just 1 inch to 13 inches.
Can't afford to add any more weight.
I would still like the CG to move back by one more inch to at least 14 ".
I have a 5 gal poly tank inside the forward fuselage.
Not sure if this is what is called a header tank.
I am thinking of adding a small 1.5 gal tank behind my seat.
Unfortunately it can only be fitted inside the turtle deck
at my neck / head level. (Already ordered a small tank.)
The plan is to fill forward main tank with no more than 2 or 2.5 gal.
1.5 gal fuel is available in auxiliary tank.
I was thinking of adding a facet pump.
But on second thought, I felt it may not really be
necessary. The pulse pump should do its job.
I am doing all this by trial and error.
Has any other builder tried to solve CG issue by
dispersing fuel to the back ?
