I had a problem with the engine quitting on takeoff that had to be 
addressed.  I pulled the entire fuel system out, and started anew.  Made 
sure the tank was as close to the firewall as possible, and high enough 
that at about half a tank, the fuel was even with the fuel nipple.  
There was an impingement of the cowling near the spinner that looked as 
if it would impede airflow, so I cut that away.  Used the largest fuel 
tubing I could.  So, after improving the fuel setup, (really just doing 
what I knew was right in the first place) I've not needed pumps or any 
other razzamatazz for perfect running.  3 different engines, not a 
deadstick among them since I re-did my work.  If it ain't 
broke..............
