I have a question.

Today while flying my first take off = was=20 normal. The second take off my fuel flow

on takeoff went up to 19.0gph then = back down=20 to 12.2 after rotation then

slowly went back to normal. = Cruised around ok=20 for 15 min then back to the airport

for a couple of circuits. No = electric boost=20 pump except I turned it on for landing.

Next take off the same thing but = max Flow on=20 take off was 18.5gph for half a second then

it went back down to 14.5. Turn = on the=20 electric boost and within 2 seconds its back up to 20.5gph.

Landed and on a back track for another = circuit the=20 engine stalled. Restarted right away with

no issues. Next circuit same = issue. Up=20 to 18.0gph then down to 15.0 while rolling down

the runway, hit the boost pump and = within 2 seconds=20 all is well. On downwind switch the

boost pump off and the fuel flow stays = in normal=20 ranges. Take off left or right tank, same issue.

Fuel 25 gal in each tank.

Fuel pressure stays normal = the whole=20 time. I checked for water in the tanks and = gascolator.

I checked underneath the cowl for = anything out of=20 place.

Engine fuel pump rebuild = required?? What do=20 you think??

Any advise would be appreciated. =

Thanks
