replace all small l= ines with large lines
the factory supplied small lines in the early mode= ls like mine
when over 18000 feet there is a momentary lack of fue= l flow despite high flow that at times stops the engine and cuts the pressur= ization and scares the beejesus of the passengers
the get around o= n those planes with small lines is to use high boost for 2-3 minutes but you= still get a very rich engine and roughness 
then switch tank= s and then go back to low flow is doable and does not cause a problem but at= times there is still roughness in the process
and remember you ha= ve to switch tanks every 15 minutes but i do it every 30 minutes unlike in t= he eve
so i advise to replace all lines to large ones
th= e fuel pump is inside the cabin, i guess you can place the fuel pump outside= but that was not on the plans,
