Greybeard...thanks for the confirmation.  And I understand why opjose likes his pumpers.  If you  have had success with something and it continues to work well for you, why would'nt you like it? 
When I buy I look at price as well as quaility.  Since I have decided on the Magnum .91 4s. a pump is not an option anyway.  Less than 200 bucks and I have read many posting from flyers who love their Magnums.  I have yet to read anything that says the suck.  Like all machines, a proper installation and break in is critical.  Correct me if I am wrong but in a Tiger 60 taildragger I should install my fuel tank so that the centerline of the tank is level with the carb of the Magnum.  True statment???
